Shizuoka — 土肥温泉
4 stays with a private bath · On the Toi coast of Nishi-Izu, on the western side of the Izu Peninsula
Every property listed here has a private bath — a reservable private bath or an open-air bath in your own room — so tattoos are a non-issue, and so is privacy.
Shizuoka · Getting there: On the Toi coast of Nishi-Izu, on the western side of the Izu Peninsula
18 of the 26 rooms have their own open-air bath, and every one of them is fed directly from the source — free-flowing Toi Onsen water facing Suruga Bay
15 rooms have their own open-air bath, all free-flowing source water — a quiet inn built around soaking after dark, with Suruga Bay in front
16 rooms have an open-air bath filled with natural Toi Onsen water, available around the clock. The source water is piped in and partly circulated for disinfection, so it is not fully free-flowing
Fully renovated and reopened in July 2026 on the Toi coast: rooms with open-air baths plus a reservable private onsen bath at ¥2,200 for 60 minutes, all on free-flowing Toi Onsen water
