Tama Sakai Tennen Onsen Mori no Irodori

Tucked away in Tokyo's Machida area, Mori no Irodori is a tranquil natural hot spring retreat surrounded by lush greenery that makes you forget you are in the metropolis. It is highly regarded for its mineral-rich, amber-colored 'Kuroyu' (black water) baths, authentic steam-saunas with auto-löyly, and open-air baths with forest views. Expect a modern, exceptionally clean facility featuring bedrock baths, massage services, and a traditional restaurant.
