About

A hot-spring facility inside a fitness club in the basement of Otemachi Financial City Grand Cube, directly connected to Otemachi Station's C2c exit and reachable via underground passage from Tokyo Station. Otemachi Onsen, a sodium chloride strong salt spring drawn from 1,500m underground, feeds separate men's and women's baths; the men's sauna is a Finnish-style loyly sauna and the women's is a mist sauna.

Day visitors (non-members) may use the facility between 10:00 and 19:00 (must exit by 19:00), choosing from plans such as bath-only, Runner's Station, or full-facility use.
