How it works
The operator, holder of the Kumanoyu trademark, lists two baths, Hekiraku and Suigyoku, each with a hinoki indoor bath and rotenburo, swapping between men and women daily at 12:30pm (cleaning 10am-12:30pm). The water is a sulfur calcium-sodium bicarbonate-sulfate spring, 63°C at the source and 43°C in the bath per the operator, with no heating, circulation or disinfection. Day bathing takes guests 12:30-3:30pm on weekdays and until 3pm on weekends and holidays, may be refused when busy, and was paused on September 29-30, 2026.
Day bathing paid at the front desk, no booking.
