Tsukisamu Onsen

What we don't check

We don't check same-day availability, how busy it is, unscheduled closures and this onsen's private bath. Policies can change without notice — please confirm with the onsen when you book and when you arrive. onsen pass provides information only: we don't make bookings, and we can't guarantee you entry.

For the water's stated health effects and contraindications, please read the notices posted at the onsen — we don't cover them. You can report an error in anything listed here.
