About Natural Hot Spring Yudonburi Sakaeyu
"Natural Hot Spring Yudonburi Sakaeyu" is a continuously evolving natural hot spring sento in Taito City, Tokyo. Every drop of water in the facility, from the faucets and showers to the baths, uses a mildly alkaline natural hot spring rich in metasilicic acid. Its signature sauna is known for introducing the industry’s first auto heat wave system, combining automatic löyly and fan-driven airflow, for intense heat and refreshing exhilaration. In addition, the "Bihou" cold plunge bath, with its fine bubbles enveloping the whole body, offers the perfect balance of the spring water’s smooth softness and chiller-based cooling. It is a must-visit sacred place for sauna enthusiasts, where downtown charm and state-of-the-art facilities come together.
