Hakone Retreat Fore
Rooms with private open-air spring bath

Kanagawa — 箱根温泉
7 stays with a private bath · About 85 min from Shinjuku by Romancecar limited-express train
Steam over the valley, cedar on the wind — and Tokyo close enough that you can be in the water by lunch.
426 dining spots and 458 places to stay are counted in 足柄下郡箱根町 — the bath is one part of the evening, not the whole of it.
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.

Rooms with private open-air spring bath
Rooms with open-air bath
Three free garden private open-air baths fed by the Kowakudani source (the room baths are not onsen)
Suites with private hot spring bath
Every bath here is private: the indoor and open-air onsen are reserved for one group at a time, about an hour in the evening and 45 minutes in the morning
Two reservable baths — one indoor, one open-air — free for staying guests and open around the clock. The milky water is natural onsen drawn from Owakudani.
Only three special rooms have a private bath — an indoor onsen bath in a 95 m² lake-view suite. The other rooms use the grand baths of the historic main building next door.
