Tokyo Sumida City
Located in Sumida, Tokyo, Spa & Capsule New Wing is a men's only spa featuring three types of authentic saunas and two types of cold plunge baths, along with a bath using Futamata calcium hot spring water, creating an ideal sequence of heat, cold, and warmth. The Bona sauna ensures stable high-humidity sweating, the Karakara sauna provides intense heat at around 110°C, and the Thermae Kai sauna allows for self-löyly to create a customizable heat experience. Cool down with two cold plunge baths at 18-20°C and 15-16°C. With an adjoining capsule hotel (124 rooms) and an in-house lounge, this facility offers a seamless experience from sauna relaxation to rest and sleep.
An artificial hot spring that dissolves the mineral deposits from Futamata Onsen in Oshamambe, Hokkaido. It enhances the bathing effect to promote blood circulation, warming the body to the core and providing a bath experience that retains heat well. Despite being an urban capsule hotel, it combines hot spring ambiance with high heat retention, making it a 'signature bath'.
A self-löyly system where you pour a ladle of aromatic water onto sauna stones, instantly raising the perceived temperature with rising steam. The steam fills the room, creating a heat curtain, allowing you to customize your preferred heat and humidity range with changing aromas. This 'customizable' sauna allows you to create peaks of humid heat at short intervals.
Equipped with a Bonatherm heater under the bench for even heating, it automatically adds water to aromatic stones to generate steam. This sauna reduces the dry sensation that can irritate the nose and throat, enveloping you in heat and humidity to induce deep sweating. Its air design minimizes heat unevenness, making it a 'core' sauna where you can sweat effectively from the beginning of your stay.
A large cold bath set at 15-16°C. With enough space for 15 people, you can even dive and swim after pouring water over your head. This main cooling facility induces a deep state of 'totonou' by rapidly switching the autonomic nervous system with a strong temperature contrast.
Set at a moderate cold range of 18-20°C, it's easy to use as the 'entrance' for cooling down right after the sauna. With a capacity for 3 people, it allows for good turnover and moderately controls heat dissipation.

Achieves intense heat of approximately 110°C while ensuring breathability through a calculated air intake and exhaust structure. The dry heat warms the body core quickly, making it ideal for the first or final session to create a sharp 'contrast' in temperature.
