Tokyo Inagi City
"Inagi Natural Hot Spring Tokinoirodori" is a day-use hot spring facility surrounded by nature in Inagi City, Tokyo. Its greatest appeal is the chance to enjoy the skin-beautifying water that springs from 1700 meters underground in luxurious free-flowing stone baths and reclining baths. The sauna area offers two types of sauna: a dry sauna equipped with powerful automatic löyly, and a herbal steam sauna where you can enjoy mud packs and salt. After the sauna, the cold plunge bath is crisp and refreshing, and outdoor air baths in the open-air area lead you to an exceptional state of totonou while feeling the fresh Tama breeze. With four types of bedrock baths and a dining area as well, it is a place where you can spend a richly colorful time to your heart's content.
