Water handling

The hotel's current bath page explicitly describes the water as natural and free-flowing. Its main configuration is one indoor bath for each sex; another hotel bath page describes a larger hotter pool and smaller cooler pool. Current pages do not list a full bath-by-bath breakdown of water addition, heating, recirculation or disinfection.

Day use is 15:00–20:00 year-round; adult admission ¥600 and child admission ¥350. Morning is reserved for cleaning. A ¥500 gallery discount is not treated as a current standard benefit because the hotel homepage says gallery access is for overnight guests. Do not assume a free shuttle for ordinary day visitors. Tattoo rules are unconfirmed.
