An alkaline simple thermal spring blended at Gero Onsen's distribution pumping station, of the classic Japanese beauty-water family. At pH 9.1 the water is alkaline with a noticeably slippery, skin-smoothing feel, while its light mineralization (374 mg/kg dissolved solids) keeps it gentle on the body. The bath is diluted with water, reheated, recirculated, and disinfected with sodium hypochlorite before reaching the large bathing hall.

About

Ogawaya has been taking guests at Gero Onsen since 1949. The five communal baths cover a range of styles: a large tatami-floor bath (the floor is woven rush, soft underfoot), an outdoor rock bath along the Hida River where you can hear the water and the frogs at night, an indoor bath, a spa room with a carbonated water pool, and a milky-white open-air section. Nine private baths are available for those who want time alone with the spring. Premium rooms have in-room onsen baths. Day use is open to outside guests on most days.

67. Ogawaya Onsen Hotel, Gero Onsen Went with a tegata for higaeri (listed Tue-Thu from 13 to 14, other days from 12 to 14). In the indoor zone there's a large bath with a smaller one inside it. The large one is hot, the small one is just warm. There's a cold water bath. Water is clear, mild smell. View through the window via a wooden lattice. The indoor bath is very cozy, spacious, and comfortable — probably the best indoor bath in Gero that I visited. The outdoor zone consists of two small baths. One is a stone bath, the other is square. Water is hot, clear, mild smell. View of the riverside promenade, but it's narrowed by a reed screen — because of this, wind barely reaches the outdoor bath area, so you can comfortably stand outside and look at the promenade during a break between soaks. The rest area has beds. Recommended for a visit, especially for the indoor bath.
