The first signs of a typhoon (taifū) rarely reveal themselves in violence. Along the Kuroshio coast, seasoned fishermen know that it often begins with color: a faint pale-yellow haze spreading across the evening sky, an early and distant omen. At such times, skippers still speak calmly. What unsettles them is the sudden appearance of wa-gumo—thin, looped cirrus clouds shaped like a horse’s lifted tail. When those clouds darken in a particular quadrant, it means the storm is no longer a rumor but already on its way. If the wa-gumo hangs low on the horizon, one may still breathe easily. But when it forms directly overhead and vanishes almost at once, it is a sign of imminent danger. The sky then begins to burn in unnatural shades of red-black, before turning as dark and dense as spilled ink. A cold, beating rain arrives in pulses—the sabui ame that fishermen recognize as the advance guard of the taifū. Under its weight, the calm surface heaves into sudden swell. Typhoon waves do not rise gradually; they erupt, sharpening into triangular peaks. By the time the sea has taken on that shape, the boat is already within the storm’s domain.
Accounts collected in the early 1990s by Hidaka (1994) describe similar scenes of atmospheric volatility along the Kuroshio coast. In one such recollection, Tanigawa Shigeyoshi, a veteran skipper, guided the Shōkai Maru into the uncanny stillness at the center of a typhoon. Only hours earlier, the vessel had been battling heavy seas; now, as the story goes, it floated in an immense hollow of pale light, encircled by ragged walls of cloud. Younger fishermen aboard had never witnessed anything like it. While two crewmen swam ashore to secure the mooring rope, Shigeyoshi is remembered as instructing them with a lesson passed down through generations: when “the sky splits open” (ten ga hogatta), a fierce following wind will arrive; the wind’s root will shift, and the backlash will strike with terrifying force. Moments later, the outer wall of the storm collapsed. Wind and rain returned in a single violent rush, tearing across the deck and shaking the wooden hull exactly as he had warned.
For Hayashi Tetsuo, then a fifteen-year-old kashiki (apprentice crew member) aboard the Shōkai Maru, this episode marked the first time he had witnessed the interior of a storm. In those days, fishermen did not speak of an “eye.” Instead, they said that “the sky has opened” (sora ga aita) or that “the wind’s root is shaking” (kaze no ne ga yurete iru). The term taifū no me—the eye of a typhoon—had not yet entered maritime speech. What Western meteorology would later conceptualize as the “eye,” Kuroshio fishermen had long described through the notion of ne: the wind’s axis, its source, the direction toward which its force gathers and from which it returns. The naoi kaze (a sudden, forceful storm wind) is said to have raged for nearly two hours, but the Shōkai Maru held fast. When the storm finally weakened, the wind faltered into intervals, exhaling briefly before going still. Fishermen described this moment as the time when “the wind begins to breathe” (kaze ga iki o shihajimeru). Afterward came the mawashi kaze, a confused turning wind blowing from all directions—the final remnant of the storm and an indication that the sea was releasing its tension.
Stories like this were never told in isolation. Along the inlets of Kagoshima Bay and the capes of southern Satsuma, skippers spoke of a whole repertoire of winds that shaped their days. The gentle summer southerly that blows into the bay from the East China Sea each afternoon, known as irebae, is said to calm by nightfall, “like a couple that quarrels by day and makes peace before bed” (hiru wa kenka shite, yoru wa nakanaori suru kaze). But when that same wind refuses to die down and continues to whip the water through the night, it is renamed shikebae, the storm-making south wind, and every boat crew tightens its guard. Elsewhere, cumulonimbus clouds towering over the open sea are called takantarō—a name that captures both their bulk and their personality. Around Cape Kaimon, skippers watch the volcanic cone of Mount Kaimon (Kaimon-dake), respectfully addressed as Kaimon-sama, as if it were the chief forecaster of the region. When a mouse-gray cap of cloud, nezun, settles over its summit like a hunting cap tipped into the wind, people say rain is on its way. On the mountain’s western side, elders describe the same cloud as if it were nibbling at the peak; on the eastern side, skippers say the mountain is “wearing a hat” (bōshi o kabutte iru). In both cases, the cloud is read as speech (Hidaka 1994).
Every morning in the fishing community of Shioya, as recalled in earlier ethnographic accounts such as Hidaka (1994), an elderly fisherman like Kayama Kinosuke would wake before dawn, just as he had since boyhood. He waited for the first light while working quietly in the yard, then stepped outside to greet Kaimon-sama. Only after bowing toward the mountain and taking a small cup of sake would he pronounce—almost casually—whether an umbrella would be needed that day. Children and young people came to ask him, and he would answer with phrases such as: “The mountain has nezun today; it will rain” (kyō wa yama ni nezun ga kakatte iru kara, ame ga furu). As noted earlier, nezun refers to the gray, mouse-colored cloud cap that settles over a mountain summit as a sign of approaching moisture. Offshore, a narrow vertical shaft of rain rising directly from the sea—hinoko (“sparks” or “fire-grain rain”)—was understood to announce strengthening winds and an increasingly rough sea. In this way, mountains, clouds, and even distant rain showers entered everyday discourse not as passive scenery, but as communicative actors in the practice of forecasting.
The stories of wind and weather along the Kuroshio coast are only one strand of a wider tapestry that stretches across Japan’s shores. On the Sanriku coast in the mid-1990s, Kawaguchi Yūjirō (1995) recorded a different, though closely related, repertoire of experiential meteorology in the fishing settlements of Yamada and Funakoshi. Visiting the poet Nakamura Toki in Funakoshi, he found that memories of sea-product processing were saturated with local weather. Nakamura recalled early-summer days when sea-urchin vendors arrived “under blinding sunshine” (mabushii hizashi no naka de), carrying buckets of cold water in which the yellow uni flesh floated, and how her mother would rise from the lunch table at once because the quality of the uni depended on light, heat, and the speed with which it was laid out to dry. Squid had to be split and salted through the night on straw mats spread directly over the beach, the women’s hands keeping pace with dropping temperatures and shifting night winds in an era before refrigeration. The processing of manbō (“ocean sunfish”), whose cartilage was prized for its “ice-like translucence” (kōri no yō ni sukitōtta), likewise hinged on whether the air remained dry enough and the breeze steady enough to ensure proper curing. Meteorology here is not a set of measurements but the felt medium in which labor unfolds.
Weather also frames local memories of wartime shipwrecks. In April 1945 a naval requisition vessel, Irago Maru, drifted off Funakoshi through a bitterly cold night; thirteen crew members died of exposure. “Because it was the season of rapeseed blossoms, we picked flowers and offered them to the bodies” (nanohana o tsuminde nakigara ni sonaeta), Nakamura remembered. The scene is anchored in a specific atmospheric contradiction: late-spring fields bright with blossoms, sea and air still cold enough to kill. A few months later, in July, another vessel, Eikan Maru, was torpedoed offshore and more than 130 soaked survivors came ashore in Tano-hama, wearing headbands inscribed with “certain victory” (hisshō). In village records the women’s association noted not only the attack but also the “great washing” (ō-sentaku) that followed, carried out in a place with very little fresh water in the height of summer heat. In such recollections, weather is inseparable from the moral drama of rescue, mourning, and exhaustion (Kawaguchi 1995: 105–22).
In nearby Orikasa, Jaishi Yaeko—married to a fisherman who also painted—described how afternoon light, tides, and wind together determined when squid and other catches could be hung to dry along the river mouth. The sight of drying surume (“dried squid”) swaying in the west wind against a marshy, reed-covered inlet told her, at a glance, both the day’s weather and the village’s livelihood. She spoke of saving every scrap of her children’s crayons and paints in a wooden box, dreaming of the day she could sketch the shifting colors of sea and sky. For Yaeko, as for Nakamura, atmospheric variation was at once a technical constraint, an aesthetic resource, and a register of memory: the same winds that cured fish also shaped how the coast could be seen and painted.
Nearly two decades later, in the aftermath of the 2011 tsunami, Kawaguchi returned to Sanriku with a different vantage point. When he visited Kosode—a small coastal hamlet in Kuji City, Iwate Prefecture—in 2013, he found the town wrapped in an unexpected cold rain, the sort that belongs more to midwinter than to early May. “The mountains were blooming with sakura, yet streaked with white, as if winter had forgotten to withdraw” (yama wa sakura ga saite iru no ni, shiroi suji ga nokotte ite, fuyu ga sashizotta yō datta): a landscape suspended between seasons. The wind that blew in from the Pacific carried an edge that felt older than the date, a lingering pulse of the ō-tsunami (“big tsunami”) (Kawaguchi 2013: 36). Along the narrow beaches between Funakoshi and Kosode, gusts pushed drifting strips of konbu (“kelp”) onto the sand, where villagers stooped to retrieve what the currents had delivered overnight—hiroi-konbu (“picked kelp”), a small but telling indicator of recent sea conditions. The water was dark and unsettled, textured by shifting turbulence and a low resonance rising from the rocks whenever the wind changed angle. Here, as on the Kuroshio coast, weather was not background but an active presence that revealed, remembered, and warned.
For the ama of Kosode—the women divers often described as “the northernmost ama” (kitagata no ama)—the sea’s behaviour served as both forecast and companion. Clear water meant visibility and a safe descent; nisemizu, the faint milky haze near the bottom, signaled awkward, unpredictable currents. A sudden cooling of the air, the tilt of whitecaps, the way gulls rose higher into the sky—these were practical indexes of risk. “You hear the wind before you see it” (kaze wa oto de wakaru), one diver told Kawaguchi (2013: 37). Their season unfolded according to atmospheric rhythms: bright, steady days that favored demonstration dives; the intrusive yūran breeze that shortened time underwater; the heavier winds of late August that quietly closed the ama season. Standing above the cliff paths, on the steep jūnimagari (“twelve bends”), Kawaguchi felt the upward rush of salt wind, slow veils of fog rising from the surface, and the uncanny stillness that precedes a shift in weather. His account, written in the long shadow of the 2011 tsunami, captured not only the coastline but the ways in which weather continued to shape the lives of those who remained.
Farther south, on islands of red earth that dry and crack after the long nagashi of the rainy season has drifted north, people look for different signs. In midsummer, when fields split and the sea itself seems to give off heat, a cool, slanting rain sometimes sweeps briefly across the land. In southern Kyūshū this fleeting shower is called sada—a rain that wets only one sleeve. Taxi drivers watch it race across city streets as a bright curtain of water that one can drive through in seconds, emerging almost immediately back into sunlight. Older women call it “hooked rain” (hikkake ame), as if it were poured from an upstairs balcony onto passersby. On Yakushima and Amami Ōshima people say, with only slight exaggeration, that “it rains thirty-five days a month” (tsuki ni sanjūgo-nichi wa ame ga furu). Somewhere on the island, every day, a shower is falling. The ancient cedar groves known as Yakusugi—trees that can exceed a thousand years in age on Yakushima’s high, mossy slopes—are often said to owe their endurance to this surplus of water. Loggers once spoke of rain as a gift sent specifically to the trees. Before felling a centuries-old trunk, they would lean an axe against it; if the axe did not topple, they took it as permission from the spirit within. Rain here is not only meteorological fact but divine delivery, soaking stone and bark with the same care. Other rains are more intimate. In the southern islands, sudden summer showers are known as natsushigure or nachigui: local words for “summer drizzle” that falls only on part of the landscape. Folk songs compare these brief, intense bursts of rain to a lover’s tears, calling them “sad yet tender rain” (kanasha ame). To those who have left the islands for the mainland, such showers become a kind of inner weather, a memory of home that falls invisibly in the mind.
Out on the open ocean, far from these villages, fishermen encounter phenomena that land-dwellers rarely see. For decades, skippers like Hayashi Tetsuo kept meticulous diaries, noting not only catches but also unusual skies, distant haze, the sting of akayu—the reddish dust blown from the Asian continent and settling on decks like colored snow. On the “weather-testing day” (tenki tameshi no hi) of the second lunar month, they would watch the sky to judge whether the coming year would be a “wind year” (kaze-doshi) or a “rain year” (ame-doshi). One summer night in the early 1960s, aboard the Tokuju Maru en route to the Miyako and Yaeyama fishing grounds, Tetsuo found his vessel enveloped in an otherworldly glow. The sea around them erupted in blue-white light as if countless fireflies had been scattered below the surface. The hull itself reflected the brightness. For more than an hour the boat ploughed through a belt of intense bioluminescence—an immense mass of yakōchū (Noctiluca), floating at a frontal boundary in the Kuroshio. By the time they reached the fishing ground, a quarter of their live bait had died, suffocated in the water they had pumped aboard from within that glowing sea. Fishermen also listen for what they call kaze no oto, the sound of the wind under water. Days before a distant taifū arrives, small swells—kai no ko, the “children of the sea”—begin to move across the surface. Divers say that the very bedrock appears to sway, that “the root stones are shaking” (neishi ga yureru). In those times, unfamiliar noises travel through the water—high, thin chirps and low rasping sounds that cannot be heard from the surface. Dolphins alter their leaps, falling back belly-up rather than headfirst when a storm approaches. The sea’s acoustic and animal signs join the visible ones, forming a layered grammar through which fishermen anticipate hazards that instruments may detect only later (Hidaka 1994).
In the estuarine waters of Ise Bay, another repertoire of vernacular meteorology unfolds, this time along the muddy flats and river mouths of Mikumo. Elder fishermen there recall a time when eel fishing and seaweed cultivation were tightly braided with the rhythms of rain and typhoon. “When the typhoon has passed, both eels (unagi) and river crabs come down from the mountains” (taifū ga sugiru to unagi mo zugani mo yama kara orimashite na), they say. If only a little rain falls and a true storm has yet to arrive, the eels hold back upstream; but once a major typhoon has swept through, “they all rush down at once” (issho ni daratto orite kuru). From the abundance or scarcity of that post-storm catch, fishers would judge whether “this year’s typhoons are finished” (mō kotoshi wa taifū wa owari ya) or whether “another typhoon is still coming” (mada taifū ga kuru zo). Here, the movements of unagi and zugani become barometric, their migrations providing a living forecast of what the season still has in store (Umi no Hakubutsukan 2005: 121–25).
Storm knowledge in Mikumo also extends beneath the water’s surface. After heavy rains, the current in the Kumozu River runs so hard that the sandy bottom ripples into ridges and hollows. Night fishing with the long wooden paddle known as a kai relies on sensing these fine changes. During the eel fishery called zuzuko, fishers explain that “eels rest in the shaded hollows of the sand” (unagi ga kage ni tomaru), and the kai is used not only for propulsion but as a probing instrument. Lowered straight to the riverbed, it feels for the slight resistance that signals a resting eel. As one fisherman puts it, “the bottom keeps moving, so we have to search for the shadows again” (soko ga ugoku de mata kage o sagasan to akan). Touch, current, and bedform together compose a micrometeorology of the river in flood (Umi no Hakubutsukan 2005: 121–25).
Seaweed cultivation brings the wind into this same field of practice. Producers of nori (“seaweed”) insist that “green nori grows best with the west wind at its back” (aonori wa nishikaze o se ni uketa hō ga ē), whereas “black nori grows best with the north wind at its back” (kuronori wa kitakaze o se ni uketa hō ga ē). A strong wind taken head-on tears the delicate fronds, so the orientation of racks and nets is continually adjusted to seasonal airflow. The distinctive taste and softness of Mikumo nori are attributed to “the good freshwater of the Kumozu River” (Kumozu-gawa no mizu ga ē), a quality elders say was damaged when agricultural chemicals and herbicides began to wash downstream. They also remember the coastline that existed before Typhoon No. 13 in 1953, “when the tidal flats were still wide and alive” (higata ga mada hiroku ikite ita koro), and how, after the storm killed eight people, concrete seawalls were built that “changed the coast completely” (kaigan ga kanzen ni kawatta). In their telling, the sudden failure of ao-nori seeding in subsequent years is linked not only to runoff but to “the bitterness of cement” (semento no aku), a way of naming how engineered shorelines and altered water flows disrupted an older balance between river, sea, and crop (Umi no Hakubutsukan 2005: 121–25).
Far to the north along the Sea of Japan, Kazama Mitsu’s Ai no kaze wa ikite iru (“The Ai Wind Is Alive”; 1988) traces a different weather-world on the Echigo and Sado coasts. Niigata Prefecture stretches for nearly three hundred kilometers between mountain ranges and sea, its winters marked by the deep snow and fierce winds of yukiguni, “snow country.” Kazama describes powder snow lifting from the ground, squeaking kyu-kyu beneath one’s feet, while offshore the waves bare their white “teeth” (shiranami ga kiba o muite) and roar throughout the day. For fishermen in sandy places like Yamakita and Igarashi-hama, the sea’s moods were once read through a dense local lexicon of winds: the cold easterly yamase that blows from high pressure off Sanriku; the long-lasting gale called dashi—sometimes hatsuka-dashi, the “twenty-day dashi”—feared as a kazan fū (“headache wind”) and kainan fū (“shipwreck wind”); the downslope Arakawa-mon that arrives hot and dry like a foehn; the nocturnal arashi blowing down from the mountains; and the summer evening ai no kaze, a north-northeast breeze about which people say, Fūfu genka to Ai no kaze wa yoru ni ha ireba yamu—like a quarreling couple, the ai wind dies away once night comes. Even as television weather maps, radar, and satellite images spread across Niigata, Kazama notes, some coastal fishers continue to match these national forecasts with their own kaze no na—wind names, changes in shiome (“tide lines”), and the glint of kōbi (“bright cloud rims at sunrise or sunset”) to judge whether to go to sea. In her depiction, local climate knowledge is both fragile and persistent, a “flickering lamp” (fūzen no tomoshibi) of inherited weather wisdom that still guides decisions along snowbound shores (Kazama 1988: 43–47, 69–72).
Stories like these circulate widely along Japan’s coasts. They are not merely tales of danger and survival, nor romantic embellishments. They constitute a dense archive of experiential meteorology: a system of knowledge in which mountains, clouds, winds, rains, animals, and even luminous plankton participate in a shared interpretive field. For the fishing communities who live with them, the sea is not a neutral expanse but a communicative, storied presence, and the atmosphere is not an abstract “background” but an active medium of relation. Weather is neither a purely physical process nor a passive setting for human action. It is a historically situated and multispecies field of practice, in and through which people apprehend their surroundings, calibrate risk, organize work, and imagine futures at sea and on shore. Precisely because it can be approached at once as material process, semiotic system, embodied experience, and narrative resource, weather resists reduction to any single analytic lens. It occupies a central position in inquiries that range from environmental perception and maritime skill to cosmology, ritual, and political economy, while continually unsettling the conceptual boundaries between “nature,” “culture,” and “climate” that often structure academic discourse.
The “weather question” thus encompasses both a tangible, physical dimension and an imaginative, symbolic realm. It concerns, above all, the ways in which weather is perceived, described, and represented. Local knowledge of weather emerges from sensory experience and material interaction with the environment, but also from individual and collective reinterpretations articulated through cultural practice and narrative expression. The meteorological knowledge of Japanese fishermen—shaped by the feel of wind on the skin, the color of distant clouds, the sound of surf and underwater kaze no oto, the sight of mountains aligning with waves—exemplifies the deep entanglement of weather, imagination, and livelihood. Their practices reveal not only how communities respond to meteorological forces, but how they co-create meaning with the very elements that sustain and threaten them.
This book begins from that world, and from the proposition that to understand weather is also to understand a particular way of living with uncertainty at the edge of the sea. It contributes to the advancement of knowledge regarding the interplay between atmospheric conditions and meteorological phenomena, highlighting their role as products of a multifaceted cultural process. Specifically, it explores how local epistemologies of weather intertwine with technical, economic, social, and ecological dimensions. Employing a phenomenological and relational approach, the book focuses on the ecological interconnectedness of practices, experiences, and cognition within the realm of local weather perception among Japanese coastal and island communities.
Parts of this work draw on a series of earlier articles by the author—published between 2012 and 2020—which are here substantially revised, expanded, and recontextualized, and which inform in particular Chapters 2, 3, and 5 (Bulian 2012, 2015, 2017a, 2017b, 2017c, 2020). Building on these foundations, and combining them with new ethnographic material, historical sources, and multi-sited fieldwork, the book examines the empirical relationship between traditional knowledge and local weather: the discernment of subtle changes in the atmosphere, the interpretation of seasonal cycles, the forecasting of weather events, and the development of decision-making practices in the context of maritime risk prevention. By adopting this perspective, the book investigates the connections between the physical experience of weather and the practical dimension of everyday activities—connections that take intricate economic and cultural forms, shaped by the interpretive lens of individual and collective experience, and that acquire cultural significance as they intersect with other domains of human life.
This thematic approach underscores the limitations of abstract or universal cognitive frameworks that are detached from the practical contexts in which they emerge, as well as of analytical perspectives confined exclusively to a macroscopic scale. In contrast, the book privileges a fine-grained, processual focus on the myriad microlevel interactions through which successive generations of fishermen and fisherwomen engage in networks of relationship that generate cultural meanings, local identities, and practical skills. From this micro-analytical vantage point, the book traces the dynamic interplay of symbolic, cultural, ecological, and economic factors that collectively contribute to the complex cultural construction of weather—a process examined in the following chapters through sustained dialogue with micrometeorological perspectives and across multiple spatial scales (macro-, micro-, and meso-).
At the macro-level, the intricate orographic configuration of the Japanese archipelago, together with its geographical position, produces a distinctive climatic profile shaped by a combination of factors: a broad latitudinal range, rugged topography resulting from relatively recent and intense endogenous processes, monsoonal circulation patterns, highly fragmented relief, and the pervasive influence of surrounding ocean currents. Together, these elements generate a remarkable diversity of climatic conditions. Within this diversity, wind plays a pivotal role, despite often being treated as secondary in climatic typologies. It is an indispensable parameter of any climatic milieu and one of the atmospheric agents that most closely interacts with human existence. Its influence is palpable in everyday perception, through direction, speed, and the weather it brings—acceleration, drought, humidity, heat, or cold. Under the pressure of these atmospheric and geoclimatic conditions, Japanese fishermen and farmers have historically developed distinct systems for categorizing, interpreting, and explaining the action and consequences of local weather agents. When examined from a climatological standpoint, local climates and microclimates reveal a highly intricate panorama in which social practices, cognitive processes, and individual adaptations converge. This includes activities ranging from the anticipation of seasonal traits to the acquisition of place-specific knowledge about microclimatic variation, as well as the assessment and mitigation of atmospheric risks through practical measures.
At the micro-level, the book centers on the relationship between communities and their surroundings within highly specific local contexts. This second research trajectory rests on a focused ethnographic approach, aimed at elucidating the connections between diverse coastal and island communities in Japan and their respective territories. From this perspective, the relationship between local communities and the land is interpreted as a dynamic process, continually reshaped within particular historical conjunctures. The overarching objective is to contribute to the exploration of the subtle interplay between modes of action and cognitive activities. To this end, the book engages several key themes derived from the ecological theory of culture: skills, behavioral responses to weather phenomena, local knowledge systems, and the emotional and evaluative dimensions associated with the dynamics of local weather. By developing an anthropological account of traditional forecasting practices within Japanese fishing communities, the book highlights both the climate-related capacities embedded in locally situated cultures and the complex web of relations between society and meteorological phenomena. In doing so, it seeks to clarify the multiple factors—symbolic, ecological, economic, and political—that converge in what cultural geographers have described as the “social–climate complex.”
Japanese fishing communities, shaped by generations of environmental adaptation, have developed a refined linguistic system that plays a vital role in interpreting maritime conditions and structuring local understandings of land, weather, and seasonal change. This book foregrounds the linguistic dimension of such knowledge, on the premise that the relationships encoded in language reflect the same spatial and ecological logics that underpin settlement practices. Proverbs, folk classifications of weather, and regionally specific terminology function as interpretive tools, revealing the perceptual and cognitive frameworks through which communities engage with their environment.
A nuanced grasp of wind within the tradition of meteorological observation—kantenbōki—requires more than empirical recognition of atmospheric patterns; it also involves the precise articulation, classification, and transmission of wind-related knowledge. At the core of this system lies the naming of wind directions, or fūi koshō. While directional names typically correspond to cardinal or intercardinal points, their exact orientation often varies by region. In some cases, even fishermen from the same harbor may employ different terms for the same wind, underscoring the highly localized nature of these systems. Moreover, fūi koshō are not always anchored to fixed compass bearings; they frequently accommodate contextual variability. Some names describe shifting winds or are tied to specific times of year, reflecting a sensitivity to seasonal rhythms and transitional phenomena. This variability illustrates the flexibility and depth of traditional classification systems, shaped not by abstract standards but by practical, embodied engagement with weather and seascape.
In a manner analogous to the once-codified systems of star nomenclature, the fūi koshō exhibit highly localized structures preserved through long-standing coastal traditions. Unlike astronomical naming systems, which in many places have largely disintegrated in contemporary practice, these wind conventions remain operative in numerous fishing communities. Despite the advent of advanced digital technologies in marine industries, the capacity for immediate, sensory-based environmental assessment—particularly in reading the wind—continues to be regarded as indispensable. When examined individually, the names associated with wind directions reveal distinct distributional patterns. Some terms display a broad, quasi-standardized presence across Japan, while others are confined to specific geographical areas or even particular localities. The coexistence of multiple designations for a single wind direction indicates a multiplicity of perspectives and interpretive frameworks, much like the regional diversity found in star-naming traditions. Regions with more extensive ethnographic or historical documentation tend to show intricate taxonomies of wind, whereas areas with less systematic recording pre-sent simpler, more uniform systems. Beyond the lexical dimension, wind-related local knowledge encompasses a substantial corpus of proverbs, beliefs, and superstitions. While some expressions are highly place-specific, others recur across disparate regions, suggesting cultural diffusion facilitated by mobility and intercommunity exchange.
The spatial distribution of such lore must therefore be examined not only as a function of environmental adaptation, but also within the broader context of social interaction and transmission. The act of naming and categorizing local winds, wave patterns, various forms of rain, and cloud formations encompasses strategies deeply entwined with practices related to the inhabiting of a particular territory. While there is a close analogy between these strategies and practices, they are brought even more effectively together by the continuous projection of profound symbolic values onto the Japanese maritime landscape. Similarly, an examination of the vernacular linguistic heritage brings out some crucial elements constituting a sort of “meteorological grammar” that continues to underpin contemporary weather forecasting practices. The book ultimately aims to show how contextualizing the practices and linguistic categories of Japanese fishing communities can help us understand certain weather categories, which reflect not only “weather morphology” but also the sociocultural and emotional meanings attributed to various local weather dynamics.
Finally, by operating at a meso-level, this book makes a contribution to the anthropological examination of the combination of global scientific knowledge and local expertise within the context of small-scale fisheries in Japan. The primary objective is to shed light on the intricate ways in which Japanese fishermen engage with weather patterns, employing a hybrid approach that harnesses the strengths of both traditional and scientific systems of knowledge. At first glance, the advanced technology and weather reports associated with the scientific discipline of meteorology in Japan may appear to have made traditional knowledge superfluous. This book seeks to challenge such an assumption by foregrounding the intricate interweaving of global scientific knowledge and deeply entrenched local know-how among Japanese fishermen. Meteorology and climatology, enmeshed within a value system closely linked to a particular physical and symbolic organization of space, move in and out of scientific treatises to insert themselves into daily activities, thereby highlighting their internal patterns.
The book thus seeks to unravel the complex dynamics that exist between these knowledge systems and explore how they are synergistically combined in order to manage and forecast weather hazards at sea. While meteorology has undoubtedly provided invaluable insights and advancements in the anthropological understanding of weather patterns, local knowledge systems have evolved over generations through observation, intuition, and lived experiences. This traditional meteorological knowledge is closely tied to the natural environment and encompasses a comprehensive understanding of the subtle signals that precede weather changes. Moreover, it is intricately interwoven with cultural beliefs, customs, and practices specific to each fishing community. The book will delve into case studies and interviews conducted with Japanese fishermen, illuminating how they engage with both global science and traditional knowledge to make informed decisions while at sea. It will explore the selection process employed by these fishermen as they discern which aspects of global meteorological knowledge align with their observations and experiences. This dynamic interplay between the scientific and the local serves as a foundation for their weather forecasting and hazard management strategies, ensuring their safety and enhancing their effectiveness in a constantly changing natural environment.
This book intervenes in the anthropology of weather and in the study of coastal fishing societies in Japan. Its empirical base is necessarily uneven, reflecting both the historical layering of available sources and the contingencies of my own fieldwork trajectory. Three regions provide the principal ethnographic points of reference: Kuzaki (Mie Prefecture), Kamishima (Mie Prefecture), and the Oga Peninsula (Akita Prefecture), supplemented by research on local materials in other sites such as Suō-Oshima (Yamaguchi Prefecture) and Sajima (Kanagawa Prefecture). In these localities I combine participant observation, semi-structured interviews, and the collection of oral histories concerned with wind nomenclature, forecasting practices, and everyday engagements with weather at sea and on shore. These contemporary materials are read alongside a broader corpus of Japanese-language scholarship in folklore studies, marine biology, environmental science, and climate history, producing an account that is necessarily multilayered in both temporal depth and disciplinary provenance.
The uneven distribution of the available evidence deserves brief clarification. Along the Sanriku coast, the Kii Peninsula, and parts of Kyūshū, earlier researchers—both academic and nonacademic—compiled extraordinarily detailed accounts of fishing livelihoods and traditional weather-forecasting practices. Their writings on wind nomenclature, cloud reading, and sea conditions often exceed what could realistically be generated through temporally bounded fieldwork alone. Accordingly, many of the detailed examples discussed in this book draw on these primary folkloristic sources alongside my own ethnographic research. This combination reflects the historical depth of Japanese fisheries research and the character of the available evidence. The ethnographic perspective advanced here is therefore intentionally composite, integrating direct fieldwork with historical and ethnographic records rather than relying exclusively on long-term residence in every locality under discussion.
A related issue concerns the temporal framing of the ethnographic present. Although Japan constitutes the overall field of analysis, the materials on which this book draws span several decades and, in some cases, more than a century of change in coastal fisheries. Much of the historical evidence derives from twentieth-century folklore collections, local monographs, and fishermen’s diaries, whereas my own fieldwork was conducted primarily during the 2010s and 2020s, in communities where digital navigation systems, mobile communication, and institutional weather forecasting have become part of everyday fishing practice.
Rather than treating this temporal difference as a simple opposition between “traditional” and “technological” forms of knowing weather, the book examines how inherited forecasting practices are retained, reinterpreted, and combined with contemporary meteorological infrastructures. The question, therefore, is not whether traditional knowledge survives unchanged in technologically dense environments, but how experiential, vernacular, and scientific forms of knowledge are articulated in practice. Wherever possible, these dynamics are explored through the juxtaposition of archival descriptions with contemporary observations from Kuzaki, Kamishima, and Oga. The book is not intended to provide a systematic nationwide ethnography of twenty-first-century forecasting practices. Instead, it should be read as an ethnographic reconstruction of historically layered cultures of weather in which contemporary practices continue to unfold in dialogue—sometimes continuous, sometimes uneven—with inherited forms of environmental knowledge.
The breadth of geographical coverage—from Hokkaidō to the Nansei Islands—introduces an additional set of constraints. Although examples are drawn from many coastal and island regions, the book neither aspires to exhaustiveness nor maintains the same empirical density across all sites. One of the guiding methodological choices has been to privilege depth over breadth wherever possible. Accordingly, the analysis progressively narrows to a smaller number of communities where both historical documentation and my own fieldwork are particularly substantial. Rather than providing a catalogue of local terms and practices, the book concentrates on the processes through which weather-forecasting knowledge is produced, transmitted, adapted, and reconfigured in specific settings. Descriptions of some regions are therefore intentionally schematic, serving as comparative reference points rather than as fully developed case studies.
This diversity of sources also shapes the analytical strategy. Ethnographic fieldwork, archival materials, historical scholarship, and contributions from marine biology and environmental science are read together to connect situated practices of reading wind and sea with broader environmental, economic, and technological transformations. Bringing these different strands into dialogue allows the analysis to move across multiple temporal and disciplinary scales while acknowledging the historically contingent character of the reconstruction presented here.
Finally, this book does not foreground recent climate change or its broader implications to the same extent as a dedicated climate-anthropological study. This reflects both the nature of the available sources and the analytical focus adopted here. Much of the historical material concerns twentieth-century practices of weather forecasting and environmental interpretation preserved in folklore collections, local histories, and fishermen’s narratives, while my own fieldwork was conducted in communities where digital weather forecasts, satellite imagery, and oceanographic bulletins have become part of everyday fishing practice. Rather than examining climate change as an explicit scientific or political category, the book explores how fishermen interpret weather variability through historically sedimented frameworks of experience. References to “strange seasons” or “unusual winds” do emerge in contemporary contexts, but they are generally understood through inherited interpretive repertoires rather than through the language of global climate change.
Within this broader framing, the first chapter introduces Japanese fishing communities as socially, economically, and environmentally situated actors whose livelihoods have long depended on close and continuous engagement with local weather and sea conditions. Through ethnographic narratives from the Kuroshio coast and historical sources, the chapter shows how weather is not approached as an abstract variable but as a lived, sensorially experienced medium that shapes daily decision-making at sea. It examines the ways in which fishers read winds, clouds, mountains, currents, and seasonal rhythms, highlighting the practical and affective dimensions of forecasting embedded in everyday work. At the same time, the chapter situates Japanese fishing communities within a wider Asian and Asia-Pacific context, where small-scale fisheries continue to rely on hybrid knowledge systems that combine experiential observation with institutional forecasts. Comparative studies from South and Southeast Asia have shown that fishers across the region routinely integrate local ecological knowledge with scientific meteorology to cope with environmental uncertainty, climate variability, and livelihood risk. Against this backdrop, the Japanese case emerges not as exceptional but as part of a broader regional pattern in which traditional forecasting practices continue to coexist with modern technologies and institutional forms of weather knowledge. The chapter introduces the relationship between local forecasting knowledge and modern meteorology not as a simple opposition between “tradition” and “science,” but as a historically evolving field of interaction shaped by technological change and transformations in coastal livelihoods. Drawing on the concept of kantenbōki—a vernacular framework encompassing empirical observation, divination, calendrical knowledge, and embodied skill—it traces how traditional practices have informed navigation and fisheries, how they were documented within Japanese climate folklore (tenki no minzoku), and how they persist within communities facing demographic aging, economic precarity, and environmental transformation. Particular attention is given to the role of the lunisolar calendar in structuring fishing seasons and risk assessment, and to the contributions of Japanese ethnology in framing weather not merely as a physical phenomenon but as a cultural and experiential domain embedded in maritime life.
The second chapter develops an anthropological analysis of how Japanese fishing communities classify and interpret weather phenomena. By examining vernacular meteorological vocabularies—particularly the naming and differentiation of local and seasonal winds—the chapter shows how fishers construct a finely textured understanding of atmosphere and sea through long-term engagement with specific maritime environments. Particular attention is given to the ways in which weather is conceptualized through local categories, linguistic distinctions, and culturally embedded modes of perception. The chapter explores how named winds, atmospheric conditions, and seascape features become meaningful elements within broader systems of environmental knowledge, contributing to locally grounded understandings of risk, seasonality, and navigation. In doing so, it highlights the richness of vernacular meteorological knowledge and the role of language in shaping relationships between weather, landscape, and maritime life. Local wind names and classificatory schemes do not merely describe atmospheric movement but encode experiential knowledge of risk, seasonality, and productive timing, offering a form of practical meteorology that operates alongside, rather than outside, scientific forecasting. This analysis is further situated within the broader climatic context of monsoon Asia. Japan’s vernacular meteorologies emerge in relation to the East Asian monsoon system, seasonal wind reversals, and the interaction of warm and cold currents that structure fishing grounds across the western Pacific. By linking local wind classifications to monsoonal rhythms and regional atmospheric circulation, the chapter highlights how Japanese fishing communities participate in a wider Asian tradition of weather knowledge while articulating it through highly localized linguistic and perceptual frameworks. Through ethnographic cases and historical sources, the chapter ultimately shows that meteorological classification is not simply a linguistic exercise but a cultural practice through which fishers negotiate uncertainty, assess risk, and align daily decision-making with environmental variability and the practical demands of maritime life.
Building on this, the third chapter shifts the focus from classificatory vocabularies to the practical work performed by forecasting knowledge—that is, how winds, clouds, currents, and seasonal transitions are translated into decisions concerning safety, timing, and livelihood. Through two interconnected ethnographic strands, the chapter shows how coastal residents read atmospheric change as a dynamic configuration rather than as a static or abstract “forecast.” In Sajima, on Sagami Bay, fishers follow an approaching typhoon through a recognizable succession of local winds, attending to their order, direction, and intensity in order to infer the storm’s position and likely trajectory. Further south and west, the chapter examines forecasting as a form of skilled observation of cloud formations and land–sea relations: practices such as takayama and okite link mountains, offshore islands, lenticular “umbrella clouds” (kasa gumo), and recurrent seasonal wind patterns into locally authoritative assessments of impending risk. The chapter then turns to Kuzaki, on Ise Bay, where forecasting is inseparable from the economic organization of small-scale fisheries and from the gendered division of maritime labor. Here, shifts in wind direction and sea conditions shape decisions about where lobster nets are set and when ama divers can safely work the seabed. Across these sites, the third chapter argues that what may be described as a form of “local science” does not stand in opposition to meteorology. Rather, it constitutes a situated mode of inference, grounded in sustained attention to micro-variations and articulated through vernacular models of danger and opportunity—one that frequently intersects with, supplements, and at times informs official forecasts in the management of everyday maritime risk.
In contrast, the fourth chapter approaches local weather perception through Japanese meteorological proverbs (tenki kotowaza), treating them not as residual folklore but as operational forms of environmental reasoning. Focusing on how small-scale fishers and coastal navigators read winds, clouds, visibility, and seasonal transitions, the chapter shows how proverbs condense long-term observation into portable heuristics for anticipating risk and coordinating practice. It traces these sayings across multiple scales, from hereditary compilations such as the Tenkimiyō—which systematizes sky- and seascape signs into tested rules of thumb—to regional proverb corpora from particularly hazardous waters, including the Tsugaru Strait. In these contexts, named winds (such as yamase, kudari, and tamakaze) and landmark-based cues function as shared points of reference that guide decision-making under conditions of uncertainty. Read in this way, proverbs operate as semiotic maps of the weatherscape: concise linguistic devices that encode place-specific meteorological taxonomies, sensory attunements, and culturally sedimented memories of danger and safety. At the same time, the chapter shows how meteorological proverbs continue to function as practical and interpretive resources, linking long-term environmental observation with everyday decisions concerning navigation, fishing, and safety at sea.
The concluding chapter explores the relationship between sensory engagement and traditional forecasting knowledge within Japanese fishing communities. It examines how weather is apprehended through embodied perception—listening to wind and waves, reading changes in light and color, sensing shifts in air and water—and how these sensory skills inform decision-making at sea. Through ethnographic examples, the chapter shows that forecasting practices such as kantenbōki are grounded in lived experience and sustained through memory, everyday practice, and close attention to changing seascapes. Weather emerges not as a passive backdrop but as an active medium through which work, risk, and livelihood are negotiated. The chapter also examines how sensory forms of environmental knowledge continue to coexist with contemporary forecasting practices and navigational technologies, illustrating the ongoing dialogue between inherited experience and scientific meteorology. In doing so, it foregrounds weather as a lived, relational phenomenon and emphasizes the continuing relevance of historically grounded meteorological knowledge within contemporary small-scale fisheries. Weather, here, is understood as something felt, interpreted, and acted upon—an integral part of life at the edge of the sea.
