From Hokkaido to Yamagata: Japan’s Ambitious Plan to Grow Coffee Outside the Tropical Belt
April 19 - 2026

On a crisp March afternoon inside a plastic greenhouse in northern Japan, bright red coffee berries stand as an unlikely testament to agricultural ambition. Here in Yamagata, nearly 400 kilometers north of Tokyo, some 40 coffee trees have grown to two meters tall—a quiet revolution taking root far from the tropical belt where the world's coffee has traditionally been born.
As climate change threatens to slash suitable coffee-growing land in half by 2050, Japanese farmers and researchers are pushing the boundaries of where coffee can be cultivated, turning to advanced greenhouse technology to nurture Arabica varieties in regions more famous for cherries and rice than for espresso.
Japan ranks as the world's fourth-largest coffee consumer, with approximately 400,000 tons consumed annually—roughly one cup per person per day. Yet nearly 100% of that supply comes from overseas. That dependency, combined with growing concerns about climate-related production declines in traditional coffee belts, has sparked a wave of domestic cultivation experiments reaching as far north as Hokkaido.
"Global coffee demand continues to climb, and areas suitable for cultivation are projected to be halved by 2050," says Kosuke Yamamoto, 66, president of Okayama-based Yamako Farm, which has been providing seedlings and technical expertise since 2020. "We're now receiving inquiries from as far north as Hokkaido and Tohoku."
Traditional domestic coffee production has been concentrated in Japan's warmer southern regions—Okinawa's Yanbaru region, the Ogasawara Islands, and parts of Kagoshima and Miyazaki—with roughly 30 farms in Okinawa alone producing small-batch, high-quality Arabica varieties like Yellow Bourbon and Typica. Total domestic production remains modest at an estimated 10 tons.
But climate change is rewriting the map. In Yamagata, Bankoku Coffee, a local food wholesaler, began cultivating coffee trees on leased farmland in 2020 as part of employee education and regional development initiatives. The project initially struggled—half of about 150 trees withered and died. But after implementing greenhouse temperature controls during winter months, the farm achieved its first harvest in 2024.
"It's still not enough to process into beans, but the yield is better than last year," says Hiroyuki Akatsuka, 55, the official who manages the farm. "We're making progress step by step."
Following a staff tasting session, Akatsuka described the results as promising: "The coffee had a smooth mouthfeel and a well-balanced tangy orange-like acidity." The company now aims to commercialize production and open an adjacent cafe "where people can enjoy the flowers and experience the harvest firsthand."
Further north on Japan's main island of Hokkaido, where winter temperatures regularly drop below freezing, researchers are exploring whether advanced greenhouse systems can make coffee cultivation viable.
Hokusei Gakuen University in Sapporo, in cooperation with Rakuno Gakuen University, has been conducting a three-year study on cultivation methods. At Yuumu Farm in the town of Shintoku, researchers utilized surplus heat generated from biogas power production to keep seedlings alive through the harsh winter. The experiment succeeded in growing seedlings up to one meter tall.
"The research ended at the end of March, but the facility continues to grow the seedlings," says Masatoshi Yuasa, 47, of Yuumu Farm. "It opens up possibilities. There's a long road ahead, but it is worth the challenge."
In Fukushima Prefecture, the Hirono Town Promotion Corporation began its own coffee cultivation experiment in 2020. While many trees have died, the corporation persists, adjusting watering frequency and volume.
"I want to succeed in cultivation and contribute to efforts to recover from the Great East Japan Earthquake," says Hirofumi Nakatsu, 68, a representative of the corporation.
The urgency behind these experiments is not lost on industry observers. Traditional coffee cultivation requires average temperatures of around 20 degrees Celsius, significant daily temperature fluctuations, and annual rainfall of 2,000 millimeters—conditions found primarily in the equatorial "coffee belt" spanning Central and South America, Africa, and Asia.
Yet a U.S. private research institute predicts that by 2050, rising temperatures and decreased rainfall will cut suitable growing areas for Arabica—the world's most popular coffee variety—by half. Meanwhile, global consumption continues to rise, projected to reach 10.16 million tons in fiscal 2026, a one-million-ton increase from a decade ago.
China's emergence as a major coffee market adds another layer of pressure. According to a U.S. Department of Agriculture report, China's coffee consumption tripled from 120,000 tons in 2010 to more than 360,000 tons in 2024.
For Japan's northern coffee pioneers, commercial viability remains distant. Coffee trees typically require three to five years to reach full production, and greenhouse heating costs in northern regions are substantial. But with each passing season, the berries grow a bit redder, the yields improve, and the possibility inches closer to reality.
As Akatsuka put it while surveying his Yamagata greenhouse: "We're making progress step by step."
In a warming world, Japan's coffee future may depend less on latitude than on innovation—and the willingness to grow something new in unlikely places.
