Umaji, Kochi

Yuzu grows here because almost nothing else can. The village of Umaji, folded into Kochi's mountain interior, sits where the forested slopes leave almost no flat ground — rivers run through, peaks rise on all sides, and the rain comes in quantities that few lowland places ever see. That geography, once isolating, became the logic of the village's economy: the citrus that thrives in wet, steep terrain, the cedar — Yanase sugi — that the forests have produced for generations.

The yuzu is everywhere in processed form: as *gokkun Umaji-mura*, the concentrated juice drink that became a nationally recognized brand, as vinegar, as jam, as miso, as preserved relish. This wasn't accidental — yuzu processing began in the mid-1970s as a deliberate act of collective self-reliance, a strategy the village calls its own. At Umaji Onsen, which opened in 1979 and serves both day visitors and overnight guests, the yuzu drinks appear at the counter almost as a matter of course.

Older layers sit alongside this. The Yakushido at Kinrinji temple dates to the Muromachi period and carries national cultural property status. Near the onsen, a former forestry railway freight car stands in display — a remnant of the Yanase Forest Railway that once moved timber through these mountains. The Kumano Shrine holds its grand festival across both the Yanase and Umaji districts. These aren't monuments set apart from daily life; they occupy the same narrow valley floor where the village simply continues its work.
