Gensen Kakenagashi Onsen, also called Sakura Yu, is located in Shōwa, Yamanashi prefecture. The bicarbonate water, pH 8, rises at 40°C, feeding an indoor bath, an open-air rotenburo and a sauna.
Insider tip — Gensen Kakenagashi means the spring flows directly from the source without recirculation or additives, the gold standard of Japanese onsen quality. The Sakura Yu cherry blossom spring in Showa-cho draws this pure bicarbonate water from the alluvial fans at the foot of the Southern Alps west of Kofu.
