Tokyo Minato City
Located in Akasaka, Minato Ward, Tokyo, Sauna Tokyo is one of the most advanced men's urban sauna facilities. It features five different sauna rooms offering a wide variety of steaming experiences. The cold plunge baths come in three types—very cold, medium-cold, and lukewarm—and the cooling sequence is clearly designed. The relaxation area offers more than 60 seats, and the facility's convenience is enhanced by its location a 1-minute walk from Akasaka Station and 24-hour operation.
A low-light sauna enveloped in silence and darkness. With light minimized, you can focus on the rhythm of your breathing and heartbeat. The temperature is slightly moderate, but the heat gently envelops the body, giving a sensation as if thoughts are melting away. It's a "quiet sauna" that calms the mind.
A self-löyly sauna using Finnish "kelo wood." In the fragrant wood, you perform löyly yourself. With high humidity, the perceived temperature exceeds 100°C. It's an "immersive" sauna where you can experience a time of quietly confronting the heat and sweating profusely in a short time.
A low-temperature steam sauna that recreates the steam baths of the Edo period in modern times. Sit in a space like a wooden box, with steam rising from your feet. The temperature is about 60°C and gentle, but the humidity is high, and sweat seeps out slowly. It's a "healing steam bath" that warms the body from the core and moisturizes the skin.
The main sauna and the symbol of Sauna Tokyo. A massive löyly sauna that can accommodate up to 40 people, with lighting, sound, and ventilation controlled by DMX. When the auto-löyly activates, steam, music, and light become one, enveloping the body in heat. It is a unique "experiential sauna" that stimulates the senses.
Recreating the traditional high-temperature dry sauna. The heat from the near 100°C infrared heater thoroughly bakes the body. Wrapped in dry heat, you can enjoy the nostalgic atmosphere of a Showa-era sauna. It's a classic-style room where you can relax while watching TV.
The cold plunge bath set at the lowest temperature. With an ultra-cold specification of around 8°C, it rapidly lowers body temperature right after the sauna, allowing for a sharp cool-down experience.
The cold plunge bath with the highest temperature. Set at 22°C with a vibra feature. It's easy to enter even for those who "aren't fond of cold plunge baths," providing a gentle option for the cool-down path.
Positioned as the medium-cold zone, entering after Frozen maximizes the cold-hot alternating bath experience. Set at 15°C, it maintains a moderate coolness, allowing for "longer stays."
Unavailable for use from 7:45 AM to 9:00 AM due to cleaning

Most of what we surveyed never even made it onto this site. This book is a further cut from what did. Our editor bathed in every onsen and sauna in it, and wrote only what they confirmed on the ground.
