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.

This Onsen rests alongside a verdant gorge carved out of rocks， where the roar of the Kinugawa River cuts through the stillness. Enjoy a splendid view of the gorge， beautiful mountains and great nature! Most of the inns located around the lake and along the valley have open-air baths (roten buro) and there are many scenic sites around the area. The Onsen welcomes many tourists during the seasons of fresh green foliage in mid-May， autumn colours in mid-October and “New Soba Festival” in November.

"Nikkozan Yumoto Onsenji Temple" is a branch temple of the world heritage site "Nikkozan Rinnoji Temple". Its history dates back to 788 when Shodo Shonin, the founder of mountain worship in Nikko, discovered a hot spring and enshrined Yakushirurikou-nyorai (the Buddha of healing) to alleviate suffering. Since the Meiji era, it has been known as a hot spring resort for common people seeking recovery and longevity.   While traditional sutra copying or Buddha tracing involves transcribing the entire sutra or drawing the entire image, Onsenji Temple offers original templates designed to be completed in approximately 15-20 minutes. For the Onsenji 16-character sutra copying, you will trace a section of the Yakushi Sutra written in light ink using a brush pen. For Buddhist image copying, you will trace the outline of a Buddha drawn in light ink using a brush pen.   Both practices allow individuals to connect with the Buddha, receiving their blessings and promoting mental and physical relaxation. The time spent engaging in sutra copying and Buddha tracing, fostering a deeper connection with the Buddha and oneself, is truly invaluable. As a token of your experience, participants who complete sutra copying or Buddha tracing and offer their work will receive a special temple stamp. Note: Brush pens are available for rental.   【About the Hot Spring】 Color of the hot spring water: Milky white Note: The source water is colorless, it turns milky white due to oxidation. * Be cautious as the colorless spring water is very hot.
