Nazuna Hakone Miyanosita

Twenty-four hours a day, Nazuna Hakone Miyanosita keeps its private onsen villas accessible in the wooded Kiga hills above the old post-town of Miyanoshita, a five-minute drive from the Hakone Tozan line and the switchback road up to Owakudani. Free parking suits drivers arriving from Tokyo without a rail transfer.

Each villa pairs its own cypress or stone bath with a private garden, so bathing hours are set by the guest rather than a shared schedule. Room service replaces a communal dining room for evening meals.

The five-star property draws couples and families seeking a self-contained soak over Hakone's larger resort hotels.
