Akazaru
Tokyo, Japan
About
Akazaru occupies a former ryotei in Kagurazaka, Tokyo, now converted into a sauna. The second-floor public sauna is men-only, with staff-led aufguss, a cold plunge and an outdoor rest space overlooking a courtyard. A separate ground-floor private room, bookable by phone, adds a cypress-wood bath and can be taken for the day or overnight.
Good to know
- Runs aufguss sessions: a guided löyly ritual where an attendant fans the steam around the room on a schedule.
- Cold plunge available on site: use it between rounds for the classic contrast cycle.
- 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.
- Urban venue: it sits inside the city rather than at a coast or lake. A session fits into a day in town.
