Sway
Tokyo, Japan
About
Sway is a private-room sauna in Minami-Aoyama, Tokyo, booked by the hour rather than shared with strangers. Each of its four rooms has its own Finnish stove, self-service aufguss and cold plunge. Two rooms allow mixed-gender use in swimwear, and a women-only powder room is available after checkout.
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.
- 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.
Hours
- Mon-Fri 09:00-05:00
- Sat-Sun/hol 07:00-05:00
Closing time is 5am the following day; the site notes hours may change and occasional maintenance closures occur.
