Origins.
Where Japan grows
and roasts its coffee.

We spent a month reading the Japan Times, Sprudge, Dig the Tea, Coffee Geography, and a stack of producer websites that had never been compiled in one place. The result is a structured record of 16 Japan-grown coffee farms and 25 of the country's leading specialty roasters. Every cell is source-cited. The raw data is openly licensed.

§ II · The Farms

Sixteen producers, seven prefectures.

Most of Japan's coffee comes from Okinawa — Yanbaru's low mountains, the Motobu peninsula, and the smaller islands. Newer trials in Aso, Yamagata, Hokkaido, and Fukushima are pushing cultivation past the tropical belt with greenhouses and geothermal heat. Click any farm for the full record.

How we compiled this

  1. Seeded the producer list from the Sprudge, Japan Times, and Perfect Daily Grind regional overviews — then deepened each entry by visiting the producer's own website or a primary feature article.
  2. Cross-referenced cultivars and altitudes between English-language coverage and Japanese-language sources (translated). Where any single source claimed a number, we listed the value but flagged the region-typical range so readers can spot anomalies.
  3. Built the roaster list by combining the Coffee Guide JP “10 notable names” framework with The Way to Coffee's Japan guide, then expanded with regional Sprudge and Brian's Coffee Spot pieces for coverage of Tokyo, Kyoto, Osaka, Nagoya, Fukuoka, and Okinawa.
  4. Every numeric claim (altitude, year, tree count, yield) is paired with the source URL in the JSON sibling file. Null fields are explicit rather than fabricated.
  5. Data ages fast in coffee. Year-stamped sources are noted on each record. We refresh this dataset every six months. The next refresh window is 2026-11.
