About

A renovated sento (spring 2010) about a minute from Numabukuro Station in Nakano, using soft water throughout. It has a mist sauna and a rock rotenburo (open-air bath) on the men's side only. Both soft and hard water can be taken home, the women's side has a free recycle corner, and the men's side has a smoking room. Other features include jet and bubble baths, a reclining bath, hot baths, a garden, and mosaic-tile artwork in the bathing room.
