Yakumo Onsen Oboko-sou

We are proud of the large open-air bath full of wildness and the hot water that is known to make your skin glow.

The popular large open-air bath has a wild atmosphere with the dynamic rock surface and the Namarikawa mountain stream running nearby. The ochre-colored water is rich in iron and warms you well. The indoor bath, which is famous for its soft water as a "hot spring of beauty," is also made of rocks, giving you a feeling of openness. After taking a day trip to the baths, you can relax in a special resting room.
