Hidden away in primeval forest, this Onsen is known as the last secret hot spring in the Kanto region. Four hot-spring facilities (Kaniyu, Teshirosawa, Nikkosawa and Haccho-No-Yu,) can be found here. Car traffic is restricted to the Onsen-kyo amidst the ancient beech woodland. Visitors can take pickup services arranged by inns or walk about 90 minutes to get there. At the moment two inns offer pickup services, and three inns (not Teshirosawa Onsen) are open to day visitors. Take your time to relax and unwind in these hidden hot spring villages.
