Kakureyu no Sato Shingenkan
Kanagawa Prefecture／AshigarakamiA hidden hot spring associated with Lord Shingen, just 90 minutes away, offering an open-air bath where you can relax in beauty-enhancing waters while surrounded by nature.
Just a 90-minute drive from Tokyo, visit Shingen's hidden Onsen. Nestled by the clear streams of the Tanzawa mountain range, the establishment features traditional Japanese Sukiya-style architecture. The Onsen, an alkaline spring with a pH of 10, is renowned as a beauty-enhancing bath, both for its external and internal benefits. There are six bathing areas, including an open-air bath with views of the clear stream and mountain nature, offering a tranquil escape. We provide three types of private baths free of charge. Enjoy rustic countryside cuisine made with seasonal ingredients, paired with Ashigara's renowned local sake.
My partner and I stayed for one night and two days. Surrounded by rich nature and wonderful hospitality, it was a truly healing trip for both body and mind. What impressed us first was the beautiful view of the Kouchi River from our Room. Opening the window, we could hear the soothing sound of the flowing water, and just watching it made our everyday fatigue melt away. The water was so clear and pristine that we even ended up playing in the river like kids again. The Onsen we had been looking forward to had excellent water quality that left our skin silky smooth after bathing. With three private baths available, we were able to relax to our heart’s content in a private space without worrying about others. Dinner in the evening was also incredibly luxurious and delicious—an absolute blissful time. Being soothed by the sounds of nature, soaking in a renowned hot spring, and enjoying great food—this is a wonderful Accommodation I will definitely visit again to Clear my mind regularly.
Yahoo!トラベルユー... 6/2/2026I found Shingenkan while planning a trip to Oyama Afuri Shrine and to try matcha tiramisu.The three private baths and the large public bath were all spotlessly clean, and the hot spring water was wonderful. The dinner dishes were beautifully presented, and everything tasted excellent as well.My senior colleague who traveled with me praised it highly too, saying they’d like to visit in every season. I will definitely return.
