Water handling

The inn drilled its own spring in 1996 and lists indoor baths, a rock-lined outdoor bath and a reclining bath. Day-use plans combine a meal, bathing and a private room. The regular bathing hours for overnight guests should not be treated as fixed day-use hours.

Day-use plans require at least three adult guests in a private party. Lunch plans start at ¥9,350 on weekdays and ¥9,900 on weekends and public holidays. Weekday evening plans start at ¥11,000; ask about weekend evenings. Reservations are by phone. These prices cover a meal, the onsen and a private room, not bathing alone.
