Hiroshima Hiroshima City

"Super Sento Unmono no Sato" is a super sento in Kurose-cho, Higashi-Hiroshima City, Hiroshima Prefecture. It uses groundwater in all baths, infused with black silica from Hokkaido (Kinkanseki), creating a gentle, mellow water that feels soft on the skin. It features two saunas: a high-temperature far-infrared sauna and a low-temperature sauna where self-löyly is possible, plus an ice-cold cold plunge bath using groundwater that leads you into a deep state of totonou. The indoor baths include an electric bath, massage bath, and reclining bath, while the open-air area offers a stone bath and waterfall bath. A background painting of Mount Fuji by a bathhouse mural artist adds a nostalgic atmosphere.
