Kosai no Yu, in Chino, Nagano Prefecture, offers bicarbonate water at 40°C. The bathhouse features an indoor bath, an outdoor rotenburo and a sauna, at the foot of the Tateshina mountains.
Insider tip — Kosai no Yu at Tateshina Onsen serves the Chino plateau in the shadow of Mount Tateshina (2,531m) — the perfectly conical volcano dominating the Yatsugatake range above the Suwa basin. The Tateshina mountain resort complex at 1,700 metres elevation is one of Japan premier summer highland retreats where ancient beech forests, alpine meadows, and volcanic lava flows of the Yatsugatake volcanic zone create a landscape dramatically different from the flat Suwa basin below, and the Tateshina lake district offers crystal-clear mountain air that has drawn health-seekers from Tokyo for over a century.
