Musashi Koyama Onsen Shimizu Yu

Musashi Koyama Onsen Shimizu Yu is a beloved, authentic neighborhood bathhouse in Tokyo that uniquely features two distinct types of natural hot spring water. Guests can soak in the therapeutic, amber-colored Kuroyu (black water) rich in organic minerals, and the golden, iodine-rich Ogon-no-yu. It offers an incredibly local, unpretentious Sento experience complete with open-air baths and saunas.
