Ishinomaki Tennen Onsen Genki no Yu is located in Ishinomaki, Miyagi Prefecture, on Japan's northeastern coast. Its sodium-chloride water reaches 41°C, with an indoor bath, sauna and massage service available.
Insider tip — Ishinomaki Tennen Onsen Genki no Yu draws naturally occurring saline spring water in a coastal city that rebuilt itself after the 2011 tsunami. The sodium-chloride baths are deeply warming and particularly welcome in the cold, damp winters of the Sanriku coast. The facility became an important community gathering point during the region's recovery and continues to hold special significance for local residents. Pair a visit with a trip to the nearby Mangattan Museum celebrating the city's manga heritage.
