Kinugawa Onsen 鬼怒川温泉 — Tochigi
Reservable private bath
Gosho-no-yu is one of the biggest reservable baths in the Ooedo group — a hall of a bath that fits about twenty people, rented by the session.
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.
