A Tranquil Forest Retreat with Historic Cultural Property Villas

Niigata Prefecture/Agano City

A serene Accommodation with just 9 rooms, nestled in nature across 6,000 tsubo.

Stay in a historic building registered as a tangible cultural property, where all meals and Onsen experiences can be enjoyed entirely in your Room from check-in to check-out. Experience a private space that feels both nostalgic and fresh, harmonized with nature, and enjoy a deeply relaxing moment.

  • Although we arrived in rainy weather, we were warmly welcomed by many staff members, making for a wonderful start that almost felt more than we deserved. The building, designated as a Tangible Cultural Property, has a rich sense of history, yet it is meticulously maintained throughout, allowing us to relax in complete comfort. In addition to the pleasantly warm and soothing Onsen, the cuisine was truly outstanding. On departure, they even took a complimentary commemorative photo and later sent it to our home—such a thoughtful gesture that made this an unforgettable memory. Everything was exceptional, including the hospitality, and this is an Accommodation we would love to stay at again. Thank you very much.

  • I booked through IKYU while traveling to Niigata to watch a rugby match, thinking I might as well enjoy an Onsen. Honestly, I expected nothing more than a simple soak, but it turned out to be deeply satisfying.The Accommodation sits spaciously on expansive grounds, and the interior is covered with tatami mats throughout. The walk to the large public bath is a bit long, but there are flower arrangements everywhere, and both the building and gardens are maintained with remarkable care. The exterior feels historic, yet the guest room was roomy and comfortable, and the garden view—surrounded by trees—was wonderful.Above all, the food was outstanding. The kaiseki course featuring seasonal ingredients from the foothills of Mt. Gozu had rich dashi in every dish, and everything was truly delicious. I also won’t forget the Koshihikari rice at breakfast—not only its sweetness, but especially its just-cooked aroma. I couldn’t help thinking, “This is genuinely amazing.”Rather than being flashy, every detail—the building, gardens, cleanliness, and cuisine—felt thoughtfully done. Niigata isn’t somewhere I visit often, but if I ever have another reason to go back, this is an Accommodation I’d want to include in my plans. That’s how memorable it was.

Warm natural materials

Warm natural materials

The entire facility, from the Rooms to the hallways, is covered with tatami flooring. You can comfortably enjoy your stay barefoot or in socks without needing slippers. We cherish the traditional design of Japanese homes and use natural materials such as solid wood and earthen walls for construction. The scent of wood, the texture of tatami, and the breathability of earthen walls—these natural elements gently soothe both your mind and body.

Onsen & Bath

Onsen & Bath

We offer a rare high-concentration radium Onsen, provided directly from the source without any added water. Despite being colorless and transparent, it is highly effective and is the only Onsen recognized for its benefits for gout. In addition to five guest rooms with private Onsen, we also have a large public bath and private baths available for your free use.

Cuisine

Seasonal kaiseki cuisine unique to the region and time of year. We focus on using locally sourced vegetables and seafood from the Niigata coast, ensuring you can savor the flavors of Niigata with ingredients procured daily. Each seasonal dish is served individually in your Room.

As you pass through the cedar-lined path, a charming and serene building comes into view. Step inside, and you'll find yourself in a world far removed from the hustle and bustle of daily life. Surrounded by birdsong and the gentle rustling of trees in the breeze, time flows quietly and peacefully.
