Naganuma Onsen (Venus no Yu) is located in Tome, Miyagi Prefecture, in northeastern Japan. The sodium-chloride water reaches 41°C, pH 7.3. The facility offers an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Venus no Yu serves Tome City in northern Miyagi where the Kitakami River basin opens into broad rice paddies flanked by the Ou Mountains. The former Toyoma district of Tome preserves remarkable Edo-period samurai estate architecture from the Date clan domains, and the regional cuisine features hittsumi wheat-paste dumplings in hot broth that have warmed northern Miyagi farming families through long winters.
