Not Busy Sauna & Cafe
Etajima, Japan

About
Not Busy Sauna & Cafe is a Finnish-style community sauna on Etajima Island in the Seto Inland Sea. It is built around a low-temperature triangular sauna, a cold plunge fed by groundwater and a café serving Finnish beer, wine and coffee. Guests pour their own löyly, and small groups can book the place privately.
Good to know
- Set up outdoors: weather is part of the experience, so dress for the walk between cabin and water.
- Cold plunge available on site: use it between rounds for the classic contrast cycle.
- Runs aufguss sessions: a guided löyly ritual where an attendant fans the steam around the room on a schedule.
- Bar on premises: drinks alongside (or after) the session, and the venue isn't dry like most outdoor sauna setups.
- Right on the sea: expect saltwater dips between rounds, cold even in summer.
Hours
- Tue-Wed closed
