About

A men-only sauna specialty facility (18+) in a building in Iwamotocho, Chiyoda-ku, a 3-minute walk from Iwamotocho Station on the Toei Shinjuku Line (Kanda x Akihabara location, grand-opened April 13, 2026 as the brand's second location after its original in Fukuoka's Tenjin district). Guests alternate between two rooms: a "deep-body-temperature sauna" with continuous humidification via auto löyly, a humidifier, and auto aufguss, and a "peripheral-body-temperature sauna" styled after a traditional Finnish footrest stove. The cold-water area offers three ergonomically designed floating cold baths. The rest area, called "Shiagaru-mu," is a windowless, conversation-free space with original background music built around the 528Hz solfeggio frequency. Admission is time-based (60/90/120 minutes), with rates that vary by time slot on both weekdays and weekends/holidays, and payment for admission is by credit card only, prepaid at booking (no cash). Towels and toiletries are provided free so guests can visit empty-handed, though toothbrushes and razors are not supplied. Tattoos are generally not permitted, but guests may enter if they can fully cover them with tattoo-concealing stickers or waterproof cream.
