Enjoy the nature of North Karuizawa in a private villa with a stunning view of Mount Asama.

Nestled in the heart of nature, "Asama Sorayama" is a private villa resort designed under the supervision of world-renowned designer Junko Koshino. Spanning over 60,000 square meters, the property features 16 accommodation villas, the restaurant "Tenku Dining," the hot spring facility "Tenku Spa," a lounge, and a dog run. Each villa offers breathtaking panoramic views of Mount Asama, allowing guests to immerse themselves in a glamping-like experience with their beloved pets amidst stunning natural surroundings. Enjoy a private and extraordinary stay with your family, partner, or friends as if visiting your own vacation home.

  • The Room was spacious and uncluttered, so it felt like pets wouldn’t be able to get into mischief. It also felt reassuring even with a baby. There was a large trash bin, and being able to throw everything away in one place was more convenient than having multiple small bins.Meals were great as well—BBQ was prepared for each Room, so we only had to grill. The meat was very delicious, and the rice had already been cooked in advance, which showed how thoughtfully everything is arranged. There is very little direct interaction with staff, but if you need anything and call, they come quickly and help.The in-Room bath was wonderful, and there is also a large public bath where you can enjoy different types of baths. The large public bath was almost private during our stay.Each Room also has a cart, making it easy to get to the large public bath. Driving the cart was a fun bonus.There are many insects outside, but measures are taken so they don’t get into the Room or onto the balcony, and there were none at all in the large public bath. A lot of insects fly around outdoors, but it’s impressive how well they prevent them from coming inside. Insect repellent is also provided, which made us feel fairly at ease.It’s an Accommodation I’d like to visit again—next time for a Multiple Night Stay.

  • We stayed for 3 nights and 4 days with our dog. There was a large terrace with a mosquito-net-style insect screen, and when it wasn’t raining we ate our meals there. It felt close to nature, the views were great, and it was wonderful. The only minor downsides were that it was a bit inconvenient to wash in the small shower room and then soak in the bath, and it felt wasteful that towels were replaced every day even though we didn’t need them changed.
