An adults-only all-inclusive Onsen accommodation chosen for its cuisine

We offer a "Full Order Style Dinner," where you can enjoy freshly prepared dishes served one by one, unlike buffets or all-you-can-eat options. Each dish is crafted with the quality of fine Italian cuisine by our former Executive Chef of Palace Hotel Tachikawa. You can savor your favorite dishes freshly made each time, creating a unique dining experience tailored just for you. The onsen features the renowned Sarugakyo Onsen water, known for its skin-beautifying properties. Enjoy it as much as you like during your stay. From rooms with semi-open-air baths to casual accommodations, we provide guest rooms suited to your preferred style of stay. Immerse yourself in the tranquility of nature while indulging in exquisite cuisine and relaxing onsen. *Please note that we do not accommodate guests who are preschool-aged or younger.*

  • My parents and I had a very comfortable stay.They said they would like to come again, which made me happy as the one who gave them this trip as a gift.All the staff were very courteous and attentive to every detail.We relaxed with coffee in our Room, warmed up to the core in the free-flowing Onsen, and slept soundly.Every dish was delicious.The acqua pazza, in particular, was the best I have ever had.

  • We stayed here to celebrate my husband’s birthday, and it turned into a truly wonderful stay.We don’t drink alcohol, and when we mentioned that, they kindly replaced the drinks in the Room refrigerator with non-alcoholic options. We really appreciated such thoughtful attention.At dinner, they also gave my husband a single rose as a birthday gift. We were deeply moved by this unexpected and lovely gesture, and it became a great birthday memory.From the open-air bath in our Room, we could look out over the lake—the view was absolutely stunning. Soaking in the open-air bath while enjoying the expansive scenery was incredibly relaxing, and being able to enjoy the Onsen at our own pace whenever we liked felt like a real luxury.Dinner was delicious as well—especially the pizza! It was so good that we ended up having two.If I had to mention one small concern, since it’s surrounded by nature there were quite a few insects. When we tried to use the open-air bath at night, many bugs (like stink bugs) had gathered there, so unfortunately we gave up bathing at that time.That said, I think that’s simply part of staying in such a natural setting. More than anything else, what stayed with us were the view from our Room, the Onsen, the food, and the staff’s warm hospitality.We were able to celebrate my husband’s birthday in a wonderful way and made lasting memories. Thank you very much.

Remarks
The Onsen is Sarugakyo Onsen, also known as a “beautifying hot spring.” Its clear, colorless water has a gentle feel on the skin and is easy to soak in for long periods without feeling tired, allowing you to warm up slowly and comfortably. In fact, some guests have traveled from far away specifically for our Onsen after experiencing skin concerns, and have even enjoyed a Multiple Night Stay. Many guests with delicate skin conditions—such as minor cuts or easily dried skin—often find it “mild and easy to bathe in” thanks to its low irritation. Enjoy this high-quality water with an excellent pH balance as many times as you like during your stay, without worrying about the time. Spring quality: Sodium-Calcium Sulfate-Chloride Spring (Hypotonic, mildly alkaline, high-temperature spring) Benefits: Beautiful skin, neuralgia, muscle pain, joint pain, frozen shoulder, sensitivity to cold, fatigue recovery, and more. *Please note: The baths switch between men and women from 22:00.*
