About Koganeyu
"Koganeyu" is a long-established sento in Sumida, Tokyo, founded in 1932. A 2020 renovation transformed it into a one-of-a-kind designer sento with a DJ booth and beer bar. Its greatest highlight is the authentic sauna and cold plunge bath in the dedicated sauna area. The men's bath features a high-temperature sauna with automatic löyly every 15 minutes, while the women's bath offers a self-löyly sauna scented with Japanese-grown hinoki cypress. The spacious cold plunge bath, with a depth of over 90 cm, is filled with crisp underground water that envelops your entire body, and when combined with open-air bathing under the city sky, it leads you to the ultimate state of totonou.
