Saitama Saitama City

"Saitama Seiganji Onsen" is a day-use hot spring facility in Saitama City, Saitama Prefecture. Its biggest draw is the luxurious free-flowing use of sodium chloride spring water that gushes from the grounds as gensen-yu, with no heating or dilution. The sauna features a dry sauna with far-infrared effects that warms you from the core, and after cooling down in the deep cold bath made with binchotan charcoal, you can enjoy outdoor bathing while gazing at the elegant bamboo grove spread out before you, creating a blissful moment. It is a soothing space where you can forget the bustle of the city and feel united with nature.
