At an altitude of 1,550 meters, unwind with a refined escape at a highland resort overlooking the lake.

—Harmony with nature, cherished in the Nordic lifestyle.— Even in those extraordinary moments of travel, we want you to relax and experience Tateshina’s beautiful nature as if it were part of everyday life. On Wednesday, January 21, 2026, our Hotel was reborn as a Nature Resort Hotel where you can feel the nature of Tateshina while staying indoors.

  • We stayed here for our family trip at the end of summer vacation. It was a special Room—the only one of its kind in the Hotel. It had the space of two Rooms plus a living area, and an exceptionally large bathroom—about the size of another Room—with a spacious bathtub where you can fully stretch out, as well as a separate shower room. The bubble-bath function had been removed, but features such as the marble flooring gave it a very luxurious feel. There were also private stairs, a ramp, and an exclusive corridor leading to this special Room, with outstanding attention to privacy. From the Room, we enjoyed breathtaking views over all of Lake Megami and the surrounding mountains. There were three large TVs, which delighted our children, and we could use the air conditioning as well, so we stayed comfortable throughout our visit. The public bath included an open-air bath and even two saunas, and the lockers were clean. From the open-air bath we could look out over Lake Megami and the mountains while relaxing in the Onsen. We enjoyed cooling off in the cold bath, watching clouds drift by, and taking our time to fully appreciate Tateshina Onsen. As it was peak season, both dinner and breakfast were buffet only; while there weren’t many items overall, each dish was truly delicious. The coffee did not seem to be freshly drip-brewed from a machine like those found at some buffets, so having a coffee machine would be nice. Next time we are very much looking forward to trying kaiseki cuisine at the basement-level restaurant as well. As an IKYU.com Diamond member benefit I requested late check-out; unfortunately it wasn’t possible due to peak season demand. Still, this is such a wonderful Hotel that we wanted to stay even longer—the Room was beautiful, spacious, and impressive in every way. Thank you also for the Diamond member gifts (a bottle of wine and souvenirs from Nagano). Since in Parking Lot No. 1 the wheelchair-priority space is shared with EV charging spaces, I think it would be better to separate them so that enough spaces can be secured to meet nighttime EV charging demand while keeping accessible parking available at all times. We arrived at 11:00 and completed check-in procedures first; the front desk staff were excellent. We requested early check-in but it wasn’t possible due to peak season; however when keys became available before 3:00 p.m., they were handed out in order of completion of procedures—so arriving early was worthwhile for us after all. We will be staying in this same Room again in the future as well; thank you in advance from our whole family for your continued hospitality. Thank you very much to all staff members.”

The lobby has been transformed into an open, lounge-style space where you can feel at one with the nature just outside the windows. Inspired by Nordic values of comfort, coziness, and tranquility, the gentle warmth of the fireplace soothes away travel fatigue.
