Water handling

The inn identifies natural spring water in the large bath and garden outdoor bath. Current official pages do not publish treatment details for each pool. The outdoor bath attached to the day-use room and the ¥5,000 private bath are explicitly not onsen.

Day bathing is ¥1,800 for adults and ¥900 for children, 11:00–22:00, last admission 21:00; towel rental is ¥300. Tattoos are not allowed in the public bath or outdoor bath. The 60-minute private bath costs ¥5,000 and is not an onsen. The older association record uses a different spring classification and is not used to fill current data gaps.
