Kotohira Onsen 琴平温泉 — Kagawa
Reservable private bath
Six different private baths filled with Konpira Onsen water, free for staying guests and open around the clock until checkout
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.
