The Teacher & the 38-Degree Slope

The story of Coco Farm & Winery begins in 1958, in a special needs junior high school in Ashikaga City, Tochigi Prefecture, where a teacher named Noboru Kawada faced a question that would define the rest of his life and the lives of thousands who followed him. His students — boys and girls with intellectual disabilities, then called by cruder names, marginalised by a society that had no clear idea of what to do with them after they finished school — were approaching graduation. In post-war Japan, there were few options for such children: some would remain at home, dependent on aging parents; some would enter institutions; some would simply disappear from society's view, untrained, unproductive, unacknowledged. Kawada could not accept this. He believed that his students, regardless of their cognitive limitations, possessed something essential — the capacity to work, to create, to contribute, to find meaning in the transformation of raw material into something useful and beautiful. And he believed that the conventional measures of intelligence and capability were not the only measures, that a person who could not solve an equation might nevertheless possess a patience, a physical stamina, a capacity for repetitive, careful labour that the academically gifted lacked.

The solution Kawada devised was radical for its time and remains radical today: he would teach his students to farm. Not merely as occupational therapy, not as a charitable make-work project, but as serious, productive agriculture — the cultivation of grapes on land that conventional farmers had abandoned as too steep, too rocky, too difficult to work. The land he chose was a hillside on the outskirts of Ashikaga, with a slope averaging 38 degrees — a gradient so precipitous that machinery could not operate on it, that a person standing upright risked losing balance, that soil and water ran off almost as quickly as they arrived. The bedrock beneath the thin layer of topsoil was Jurassic — 150 million years old, formed in the ancient seas that covered this part of Japan when dinosaurs walked the earth. The rock was hard, fractured, and unforgiving: clastic sedimentary stones, chert, basalt, and mélanges — the chaotic mixtures of rock types that form at tectonic boundaries. No sensible farmer would plant vines here. Kawada, with his students, did it anyway.

The work was brutal. The students — teenagers with intellectual disabilities, some with physical limitations as well — had to clear the scrub and stones by hand, to break the rock where they could, to build terraces where the slope allowed, and to plant vines in holes chipped into the bedrock with hammers and chisels. The soil they had to work with was minimal — 20 to 100 centimetres of loam over solid stone — and the nutrients it contained were leached away by the rain that ran down the slope before it could be absorbed. But Kawada and his students persisted, year after year, planting, pruning, harvesting, and learning. The grapes they grew were not initially for wine — they were table grapes, sold at local markets, providing the students with an income and a sense of purpose. But Kawada had larger ambitions. He believed that his students could make wine, real wine, wine that could stand alongside the products of the great wineries of Europe and Japan. And he believed that the quality of the wine would prove the capability of the makers — that excellence in the bottle would silence prejudice against the hand that held it.

The path from table grapes to wine was long and complex. In 1980, Kawada established Coco Farm & Winery Ltd. as a commercial entity, creating the structure that would allow the enterprise to grow beyond the school and to employ adults with disabilities in a sustainable, long-term way. In 1984, the winery obtained its license to produce wine — a milestone that transformed the operation from a farm into a winery, from an educational project into a commercial enterprise, and from a local curiosity into a producer with national ambitions. The Kokoromi Gakuen — the welfare facility for adults with intellectual disabilities that Kawada established alongside the winery — became the permanent home for the workers who had begun as his students, and the model for a new kind of social enterprise: one in which the product was not charity but quality, and in which the workers were not recipients of aid but participants in a craft. The motto that Kawada inscribed on the heart of the enterprise — "Put all your strength into something that will ultimately disappear" — was not a counsel of despair but a declaration of faith: that the value of work lies not in its permanence but in its doing, that the act of creation is its own reward, and that a wine drunk and gone is nevertheless real, and the labour that made it is nevertheless meaningful.

At Coco Farm & Winery, the winemaking philosophy is grounded in two uncompromising commitments: the use of wild yeasts for fermentation, and the rejection of herbicides and chemical fertilisers in the vineyard. These are not merely technical choices; they are moral positions that reflect the enterprise's broader philosophy of naturalness, honesty, and respect for both the material and the people who work with it. The wild yeast commitment means that every fermentation is initiated by the indigenous yeast populations that live on the grape skins, in the vineyard air, and on the surfaces of the winery — microorganisms that have evolved in symbiosis with the Ashikaga environment, adapted to the steep slopes, the Jurassic bedrock, and the continental climate. These yeasts are not selected for their predictability or their neutral aromatic profile; they are allowed to ferment according to their own logic, producing wines that express the specific microbiome of the Coco Farm terroir. The result is wines of extraordinary vitality and complexity — wines that change from vintage to vintage, that evolve in the bottle, and that carry the living signature of the place where they were made.

The rejection of herbicides and chemical fertilisers is equally fundamental. The thin soils of the Jurassic slopes are vulnerable to erosion and depletion; the use of synthetic chemicals would damage the fragile microbial ecosystem that has developed over millions of years and that is essential to the health of the vines and the character of the wine. Instead, Coco Farm builds soil fertility through composting, cover cropping, and the natural cycling of organic matter — practices that are labour-intensive but that produce a vineyard ecosystem that is self-sustaining, resilient, and expressive. The steep slopes, paradoxically, assist in this approach: the rapid drainage prevents waterlogging and reduces fungal pressure, and the constant air movement inhibits the development of the pests and diseases that thrive in still, humid conditions. The vineyard is not merely a grape factory but a living system — a polycultural landscape where fruit trees, native plants, and beneficial insects coexist with the vines, creating a habitat that supports biodiversity and produces grapes of natural health and concentrated flavour.

The influence of Bruce Gutlove — the American winemaker who came to Coco Farm in 1989 at Noboru Kawada's invitation — has been transformative for the winery's technical development and international reputation. Gutlove, who had trained in California and established himself as one of Japan's most respected wine consultants, brought to Coco Farm the practical knowledge of how to make stable, delicious, commercially viable wine using natural methods. His influence is visible in the fermentation management, the blending decisions, the quality control systems, and the overall approach to winemaking that distinguishes Coco Farm from more improvisational natural wine producers. But Gutlove did not impose a foreign style on the winery; he worked with the specific characteristics of the Ashikaga terroir, the specific qualities of the Japanese grape varieties, and the specific capabilities of the Kokoromi Gakuen residents to develop a winemaking approach that is both technically sound and philosophically coherent. The wines that emerge from this collaboration are unmistakably Japanese — made from 100% Japanese grapes, fermented by Japanese wild yeasts, and expressing the mineral character of Japanese Jurassic bedrock — but they are also wines of international quality, recognised and served at the highest levels of global diplomacy and commerce.

The 100% Japanese grape commitment is a defining characteristic of Coco Farm's production. Unlike many Japanese wineries that import grape juice or bulk wine from abroad to supplement domestic production, Coco Farm uses only grapes grown in Japan — from its own estate vineyards and from a network of contracted growers across seven prefectures. This commitment is not merely patriotic; it is practical and philosophical. Japanese grapes, grown in Japanese soils and fermented by Japanese yeasts, produce wines that express the specific character of the Japanese archipelago — its volcanic and ancient geologies, its monsoon climate, its distinct seasons, and the agricultural traditions that have shaped its landscapes for millennia. The varieties cultivated include both indigenous and international grapes adapted to Japanese conditions: Koshu, the ancient variety of Yamanashi; Muscat Bailey A, the Japanese hybrid; Delaware, the American variety that has found its home in Japan; and international varieties such as Chardonnay, Merlot, and Cabernet Sauvignon that have been grown in Japan long enough to develop distinctly Japanese expressions. Each variety is handled according to its specific characteristics, with fermentation and ageing protocols designed to preserve its natural qualities rather than to transform it into something it is not.

The winemaking at Coco Farm is therefore a unique synthesis: the social mission of Noboru Kawada, the natural philosophy of wild yeast and organic viticulture, the technical expertise of Bruce Gutlove, the labour of the Kokoromi Gakuen residents, and the specific terroir of Jurassic bedrock and 38-degree slopes. The white wines — Koshu, Chardonnay, and others — are fermented cool to preserve freshness and aromatics, aged in a combination of stainless steel and neutral oak, and bottled with minimal filtration to preserve their vitality and texture. The red wines — Muscat Bailey A, Merlot, Cabernet Sauvignon, and blends — are fermented with gentle extraction, aged in French oak barrels, and blended with the intuitive skill that comes from decades of experience. And all of them share the Coco Farm signature: the mineral backbone from the limestone fragments in the mélanges, the chalky texture from the chert-derived soils, the complexity of flavour that comes from ancient bedrock and patient, attentive labour. These are not wines that shout; they are wines that reveal — slowly, quietly, and with the depth that comes from 68 years of continuous production by hands that have learned, through repetition and care, to understand the material they work with.

To understand Coco Farm & Winery, one must understand that it is not merely a winery; it is a social welfare corporation — a legal entity in Japan whose primary purpose is not profit but the welfare of its members. The Kokoromi Gakuen, the facility that houses and employs the adults with intellectual disabilities who make the wine, is not a charity or a sheltered workshop; it is a community of workers who produce a product of recognised excellence, who earn wages for their labour, and who participate in the full cycle of agricultural production from planting to harvest to bottling to sale. This is not a tokenistic inclusion of disabled workers in a marginal role; it is a genuine integration of people with cognitive differences into the core productive activity of the enterprise. The residents prune the vines, harvest the grapes, operate the presses, clean the tanks, label the bottles, and pack the cases — not under constant supervision but as members of a team, working alongside professionals, contributing their specific skills and capacities, and learning through doing the crafts of viticulture and winemaking.

The philosophical foundation of this approach is Kawada's radical belief that cognitive difference is not deficiency — that a person who learns slowly, who thinks concretely, who requires repetition and patience, possesses capacities that the cognitively typical lack: the capacity for sustained attention to repetitive tasks, for physical stamina in difficult conditions, for loyalty to colleagues and institutions, for finding joy in the simple pleasures of work well done. The steep slopes of Coco Farm, which make machinery impossible, are not merely a viticultural challenge; they are a social opportunity — a workplace that requires exactly the qualities that the residents of Kokoromi Gakuen possess in abundance. The hand-worked vineyard is not a nostalgic throwback to pre-industrial agriculture; it is a modern, intentional, socially progressive form of production that leverages human diversity rather than marginalising it. The wine that emerges from this labour is not a charitable product to be purchased out of pity; it is a competitive product to be purchased because it is excellent — and the excellence is the proof of the social model, the evidence that cognitive diversity, when properly supported and directed, produces results that uniformity cannot match.

The diplomatic recognition that Coco Farm wines have achieved — the G8 Summit, the prime ministerial dinners, the Apostolic Nunciature, the JAL first class cabins — is not merely commercial success; it is political and social validation. When a wine made by adults with intellectual disabilities is served to heads of state, to cardinals, to business leaders flying between continents, it carries a message that transcends the liquid in the bottle. It says that quality is not the exclusive property of the cognitively gifted, that excellence can emerge from unexpected places, and that the conventional hierarchies of human value — which place the intellectually brilliant above the intellectually limited — are not merely unjust but factually wrong. The diplomats and dignitaries who drink Coco Farm wine are not performing an act of charity; they are enjoying a product of genuine excellence, and in doing so, they are unwittingly participating in a radical social experiment that challenges their own assumptions about capability, worth, and the distribution of human potential.

The future of Coco Farm & Winery is tied to the continuation of this dual mission — the production of excellent wine and the employment of adults with intellectual disabilities — in a world that is slowly, unevenly, but unmistakably moving toward greater recognition of cognitive diversity. The winery's scale — 250,000 bottles annually — provides the economic foundation for the social mission, demonstrating that the model is not merely viable but scalable, not merely sustainable but replicable. The technical expertise that Bruce Gutlove and the professional winemaking team provide ensures that the quality continues to improve, that the wines remain competitive in an increasingly sophisticated market, and that the recognition that the winery has achieved continues to grow. And the Jurassic bedrock, the 38-degree slopes, the wild yeasts, and the ancient varieties continue to produce grapes of distinctive character — the material foundation that makes everything else possible.

In an age of industrial wine production, of homogenised flavours and marketing-driven branding, Coco Farm & Winery stands as a radical alternative — not a small, romantic, underfunded project but a large, professionally managed, commercially successful social enterprise that proves natural methods and cognitive diversity can produce wines of international excellence. Noboru Kawada, Bruce Gutlove, Hideki Ishii, Toyoichiro Shibata, and the residents of Kokoromi Gakuen are not merely making wine; they are making a case — that work has value regardless of who performs it, that quality is not the property of the privileged, that steep slopes and ancient rock and human hands can produce something finer than flat land and machines and chemicals, and that a wine drunk by a head of state and a wine drunk by a farm worker are both real, both meaningful, and both the products of labour that deserves respect. The 68-year tradition, the Jurassic bedrock, the 38-degree slope, the wild yeast, the social mission, and the diplomatic table: all united in one bottle, one enterprise, one unanswerable argument for the dignity of all who work.
