Yamanashi Fruit Onsen, operated as Pukupuku, is located in Yamanashi city, in Yamanashi Prefecture, an area known for its orchards. Its sodium-chloride thermal water is kept around 40°C (pH 7.3), with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Yamanashi city (山梨市) sits in Japan's premier fruit-producing basin — peaches, grapes, cherries, and plums ripen on the sun-drenched slopes rising from the Kofu Basin floor, with Mt. Fuji's snow cap visible to the south. 'Fruit Onsen Pukupuku' (the playful name evokes bubbling water) offers seasonal fruit-themed baths: peach baths in July, grape baths in September, with local fruit extracts mixed into the artesian sodium-chloride water. The Enzan wine district with its ancient Koshu vines begins just east of the city.
