Enjoy a relaxing moment in a heavenly Onsen resort village at an altitude of 1,800 meters.

A Resort Hotel at an altitude of 1,800m, where you can enjoy one of Japan's finest highland Onsen with breathtaking views. Soak in the open-air bath with the scent of sulfur and milky white waters while admiring the majestic mountains. At night, experience a mystical moment under a sky filled with countless stars. Choose from three restaurants: Japanese, Western, and buffet-style dining. In winter, enjoy activities such as skiing on powder snow slopes or playing at the kids' park.

  • The food is delicious. There is crab, but that’s not all. The roast beef, cheese pasta, and special mapo tofu are freshly made and tasty. The other dishes are also very satisfying.Breakfast is well prepared and satisfying too. If you stay here, we recommend booking a plan with both dinner and breakfast included.The Onsen has pleasantly cloudy water.

  • Manza Onsen is a sulfur spring I had always wanted to visit. I went by car in early November, but it seemed to have snowed the day before, and the general road from Nagano was closed due to ice! When I tried another route, it was also closed! The only option was the Manza Highway, so getting to the Hotel was quite challenging. As I got closer to the Hotel, the scent of sulfur filled the air, and my excitement grew! After having dinner first and relaxing in my Room, I headed to the Onsen. Since I went late at night, the open-air bath was practically private, and as expected, the water quality was amazing! It seems you can also use the hot springs at Kogen Hotel across from here; next time I'll come earlier and fully enjoy it!
