Sennennoyu Koman
Two free private baths in the annex, filled with source water (room baths are not onsen by local ordinance)

Kinosaki Onsen 城崎温泉 — Hyogo
Reservable private bath
A small inn with two reservable onsen baths, free for 45 minutes — apply at check-in and soak in private before the sotoyu round.
Willows over a canal, wooden inns along one street, and everyone out strolling in yukata after dark. The private bath works like this: you book it, it's yours. Door closed, steam up, nobody else's schedule anywhere near you. Take the late slot — night air on wet skin is the whole point.



Private-bath and water facts were checked against the property's official site and Japanese booking pages in November 2026. Room plans change — confirm the private bath is included in the plan you book.
