About

An urban spa inside OIMACHI TRACKS, a complex directly connected to JR Oimachi Station. The men's bath features Japan's first "Tram Sauna," inspired by the train depot at Oimachi Station: a space recreating the interior of a wooden streetcar, where pressing a button by your seat releases steam along with the scent of Western red cedar.

The other sauna, the "Wöyly Kelo Sauna," uses rare kelo wood from the benches to the walls, with a unique structure in which water running down the walls releases fragrance each time it touches the kelo. The women's "Woven Sauna" arranges herbs, medicinal plants, and flowers in woven baskets and flasks, so the steam gathers up their scents.

The men's side has two cold plunges, a "single" bath below 10°C and one at around 15°C, allowing guests to enjoy "cold-cold contrast bathing" between plunges of different temperatures. The building also houses a coworking space where you can head straight to your desk after the sauna, and a restaurant that carries on popular dishes from its sister facilities.
