A famous hot spring in Fukagawa where tradition and modernity blend
Tokyo Koto City
"Fukagawa Onsen Tokiwayu" is a long-established bathhouse in Koto City, Tokyo, with 80 years of history. A full renovation in 2023 transformed it into a modern, spotless space while preserving its traditional miya-zukuri exterior. Its biggest draws are the amber-colored natural hot spring and the high-purity soft water used throughout the entire facility. The men's bath features a sauna equipped with powerful automatic löyly every 20 minutes, and its intense hot air creates a stimulating sweating experience that is very popular. Add in the crisp, cold soft-water cold plunge bath and the expansive open-air rest area, and you can enjoy an ultimate totonou time while taking in the atmosphere of old-town Tokyo.
