SodiumChloruresBrome
Yuami, in Yoshikawa, Saitama Prefecture, is fed by natural sodium-chloride hot-spring water at 41°C. An indoor bath, outdoor rotenburo and a sauna are available on site.
Insider tip — Yuami serves Yoshikawa City on the Motoarakawa River in Saitama Prefecture, celebrated throughout the Tokyo metropolitan area as Japan catfish (namazu) capital where local fishermen have harvested freshwater catfish from the Edo River and Arakawa wetlands for centuries. The Yoshikawa Namazu Festival each autumn celebrates the catfish cuisine tradition that established this river city as Japan foremost catfish restaurant destination, and the city waterways preserve the ecological character of the pre-industrial Tokyo lowland river system where catfish, carp, and eels sustained riverside communities for a thousand years.
