The luxury of natural hot springs throughout the facility, and the soothing retreat brought by an authentic Rocky Sauna
Tokyo Shinagawa City
"Nakanobu Onsen Matsunoyu" is a luxurious sento in Shinagawa Ward, Tokyo, where natural hot spring water is used throughout the entire facility. From the faucets and showers to every bath, soft-on-the-skin natural hot spring water flows generously. Its signature Rocky Sauna has a log-house-style design made from stacked cypress logs, and the automatic löyly performed every 5 minutes maintains a comfortable level of humidity. The cold plunge bath also uses natural hot spring water, creating a mellow cooling experience. There is also an outdoor air bath area overlooking a Japanese garden, letting you enjoy the feeling of a full-fledged hot spring trip right in the middle of the city.
