The verdict
Private sauna rooms in Akasaka, each with self-poured löyly, an auto-Aufguss fan and its own filtered cold bath at 14 to 17 degrees; tattoos are no problem.
Ninety minutes in your own room
Two reviews, from 2025 and 2026, paid ¥6,000 for 90 minutes. Each room has a sauna with self-löyly and an automatic Aufguss fan, a cold bath kept at 14 to 17 degrees by a chiller, and a rest area.
Mixed pairs must wear swimwear, which you can rent for ¥700; sauna hats are ¥300. Morning slots in the VIP room, for up to four, now run 180 minutes for the 120-minute price.

Akasaka Sauna scores 6: a 4.7 from 225 reviews, the sauna, the cold bath and prices on its own site.
