Tennen Onsen Hot Kamo, in Higashihiroshima, Hiroshima prefecture, has sodium-chloride water at 41°C, with an indoor bath, an open-air outdoor bath and a sauna.
Insider tip — Hot Kamo serves the Kamo town area of Higashihiroshima, a university city whose Saijo district produces some of Japan most celebrated sake. The spring water draws from sediments beneath the Bingo Plain, and a tasting tour of the Saijo sake breweries pairs naturally with a long, relaxing soak.
