About
Sustaina Sauna is a one-group, private-hire wood-fired sauna at a fixed site in Kiwadashima, Nikko. Booking covers the whole cabin for up to eight people, with a self-service löyly and an outdoor rest deck.
Good to know
- Wood-fired heat: softer, heavier löyly than electric, and the smell of the stove is part of the room.
- Set up outdoors: weather is part of the experience, so dress for the walk between cabin and water.
- Bookable as a private session: rent the room for your group rather than sharing with strangers.
- Set in nature, away from the city, so bring a car or plan the transfer in advance.
