About Kasukabe Yumoto Onsen
"Kasukabe Yumoto Onsen" is one of the largest day-use hot spring facilities in the Kanto region, boasting a vast site in Kasukabe City, Saitama Prefecture. A major renovation in 2023 significantly upgraded the sauna and bathing facilities. The alkaline simple spring that gushes up from underground has a soft, gentle feel and lets you fully enjoy the appeal of the natural spring water. The sauna features a massive stadium sauna that can accommodate more than 30 people. Daily aufguss events let you experience powerful steam and wind from skilled heat bath masters. With a crisp, refreshing cold plunge bath, outdoor bathing in the open-air area, and even a large swimwear-friendly pool called Thermes, it is a leisure hot spring spot where you can spend the whole day having fun.
