About
A 5-minute walk from Tokyo Metro Marunouchi Line Yotsuya-sanchome Station, or 7 minutes from Toei Shinjuku Line Akebonobashi Station. Opened on February 27, 2026, this men-only sauna-only facility sits down a back alley of Arakicho, a former geisha district, at Arakicho Gardens 103. Built around a "deep sea" concept, it offers a "Deep Dive" sauna room wrapped in quiet darkness and shimmering blue light, along with a cold plunge kept at 15-17°C. Hours are 13:00-23:00 on weekdays and 11:00-23:00 on weekends/holidays (last admission 21:50), with no fixed closed day. Pricing is hourly, from ¥1,800 on weekdays and ¥2,100 on weekends/holidays (each additional 30 minutes adds ¥500), with a face towel and bath towel lent free of charge. Cash is not accepted; payment is by credit card, transit IC card, or QR-code payment only. There is no on-site parking; nearby coin-operated parking lots are suggested instead.
