  • The Room, meals, bath, and service were all extremely satisfying.The water was so delicious that I drank too much—on the way home, you may want to be careful as you might need to use the restroom more often.

  • We stayed for one night during summer vacation as a family of three. The food was delicious, and the bath was great. The Onsen kept us warm for a long time and helped relieve the fatigue from a long drive. Although dinner was buffet-style, we ate in a separate room from where we picked up the food, so we could enjoy our meal in a relaxed setting. The toasted marshmallows were also delicious. It’s close to the ropeway, and we received a discount, which felt like a great deal. The Accommodation Fee also felt very reasonable compared with other areas. We would definitely like to stay again!

The resort's concept is "Act and Rest." Based on the idea that a comfortable mind and body "Rest" begins with fully engaging your senses through "Act," we offer activities that connect you with nature. Using the natural spring water "Onogawa Spring," selected as one of Japan's Top 100 Famous Waters, as a starting point, we explore the natural environment of Urabandai at an altitude of 1,040m. We propose experiences that actively immerse you in nature while unintentionally stirring your senses and curiosity. After moving your body and mind extensively, retreat with meals featuring local ingredients, Onogawa spring water, Onsen, and refreshing mountain air. Despite being active all day, you'll feel lighter than spending a weekend at home. At EN RESORT Grandeco Hotel, we offer such rejuvenating moments for you to enjoy.
