A hidden Karuizawa Hotel where you can rejuvenate your mind in a space inspired by natural stone

The Ancient Hotel began its history in 2011 in the Karuizawa National Park with the concept of "Rejuvenation and Refreshment of the Soul." Amidst the vast nature that changes with the seasons, forget the daily hustle and the city's noise, and enjoy irreplaceable moments. Please relax and enjoy your stay.

  • We had a truly wonderful stay.We stayed for two nights with our 1-year-old daughter.Dinner and breakfast were included, and the food was outstanding. They thoughtfully accommodated our child’s meals, taking her egg allergy and the size of the ingredients into consideration, and she was very happy. The staff also looked after her throughout, so we could enjoy our meal with peace of mind.The Room has special touches that help you forget the busyness of everyday life.Thanks to that, we were able to enjoy an extraordinary experience we don’t usually get to have.We would love to return again next time.

  • Everything—the Facility, the service, and the meals—was outstanding, making this an unforgettable stay. First, regarding the Facility: because it is located in the forest, the air is wonderfully fresh, and you are surrounded by greenery as far as the eye can see—a truly refreshing environment. You can sense wildlife you would never encounter in the city, such as wild birds, squirrels, and stag beetles, and feel close to nature. The Onsen has a clean, refreshing quality to it, and there is also an open-air bath where you can soak while looking out over the forest. As for the Room options, there are several with different themes and atmospheres; we stayed in a corner Room on the first floor. From every window we could see lush green trees and fully enjoy a forest-bathing experience. (Our Room faced the Shiraito Highland Way, so there was some traffic during the day; if that might bother you, it may be worth checking availability for a Room not facing the road. For reference, there were almost no cars early in the morning or at night—only during daytime.) The service impressed us with hospitality that ranks among the best of any Hotel we have stayed at. My wife was pregnant and also left-handed; without us having to mention anything, they thoughtfully took care of details such as loungewear sizing as well as providing cushions and blankets and adjusting table settings accordingly. Thanks to their attentiveness, we were able to relax and enjoy both our stay and our meals with peace of mind. The meals were also the best we have had among all Hotels we’ve stayed at so far. The dishes were based on Japanese cuisine—we thoroughly enjoyed Shinshu vegetables—and even the main meat course was truly delicious. It was such a wonderful Hotel that we didn’t want to leave—and it made us want to come back again soon. Next time I’d like to bring more family members and stay longer.
