Onsen Tengoku Sakura Yu is located in Kōriyama, Fukushima Prefecture. Its sodium-chloride water, at 41°C, fills an indoor pool and an outdoor rotenburo, with a sauna rounding out the facilities.
Insider tip — Tengoku Sakura Yu, the cherry blossom heavenly spring, rises in Koriyama, the commercial hub of Fukushima Prefecture. Lake Inawashiro, one of Japan largest, and the Ura Bandai highland wetlands are close by, and Tsurugajo Castle at Aizuwakamatsu is easily reached for a day of samurai history.
