Jindaiji Tennen Onsen Yumori no Sato is located in Chofu, in the Tokyo area. Its sodium-chloride water surfaces at 41°C. The site offers an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Jindaiji Tennen Onsen Yumori no Sato draws a natural sodium-chloride spring from deep beneath the Tokyo metropolitan area, a rarity amid the urban density of the Musashino plateau. Located near the historic Jindaiji Temple and its famous soba district, the bathhouse integrates effortlessly into a day of cultural exploration. The deep Kanto aquifer salt water delivers strong warming retention, and the post-bath heat lingers noticeably longer than in tap-heated sento. The facility's large rest hall and garden encourage guests to extend their stay well beyond the bath itself.
