A Kochi hot spring inn with a signature open-air shio-yu overlooking the Pacific and an authentic sauna
Kochi Nakatosa, Takaoka District
Black Current Honjin (Kuroshio Honjin) is a hot spring inn in Nakatosa Town, Takaoka District, Kochi Prefecture. It boasts an outstanding location with panoramic views of the vast Pacific Ocean below and the twin islets listed among the Tosa Ten Views. At the signature open-air bath guests can enjoy shio-yu, a saltwater bath made by boiling seawater, while the indoor bath offers hot spring water heated from an underground cold spring. After working up a sweat in the authentic dry sauna, you can refresh yourself with an exhilarating cool-down in the outdoor rock-built cold plunge bath while feeling the sea breeze. A uniquely refreshing experience awaits, one that makes you feel at one with nature.
TypeNatural Hot Spring
There are two large communal baths, a white granite bath and a rust-colored stone bath, which alternate between men and women daily. They use water drawn from an underground cold spring that is heated, and through the large windows you can take in sweeping views of the Pacific and the twin islets. Time spent soaking while admiring the spectacular scenery is truly special and deeply restorative.
TypeSpecialty Bath
The inn's signature open-air bath uses shio-yu, a saltwater bath made by boiling seawater drawn from the Pacific. Overlooking the ocean below and accompanied by the sound of the waves, guests can enjoy blissful moments. The saline water helps firm the skin, and the warm feeling after bathing lingers.
