Savor a luxurious moment that will fill your heart—where ever-changing scenery, breathtaking baths, and exquisite cuisine come together. We sincerely look forward to welcoming you.

  • I stayed on a day when the Gono Line was suspended due to bad weather. Luckily, there was a bus from Hirosaki to Ajigasawa Station.I arrived earlier than my train would have, but they accommodated the change with their shuttle service, so I was able to spend the day relaxing in the hot springs. The booking center staff were also very reassuring over the phone.Soaking in the open-air bath while watching fierce winds whip up foaming waves on the Sea of Japan was a memorable experience. The water felt silky and gentle on the skin, making me want to bathe again and again.Everyone, from the front desk and shuttle staff to the dining staff, greeted me with genuine smiles and warm hospitality, making my stay very pleasant.My only concern was that the slippers provided for walking around the property were very difficult to walk in. I would have appreciated another footwear option, preferably disposable, although I realize that would be less eco-friendly. My own shoes were trekking boots for my upcoming walk around Juniko, and they were a hassle to put on and take off, so I used the slippers.On the shuttle ride to the station the next day, the driver said, “You'll have a wonderful walk around Juniko today.” Just as promised, the sun came out in the morning, and I got to see the beautiful Aoike Pond.It was a short stay, but I was able to relax. Thank you very much.

  • On our first trip to Aomori, we stayed the night before the Nebuta Festival for the first time, and everything—the meals, drinks, service, and Onsen—was excellent. Our three-generation family was very satisfied when we left. If I had to ask for one thing, a massage chair would make it even better. We were completely satisfied and truly enjoyed Aomori. Thank you very much.

Onsen
Natural thalassotherapy benefits: “Fossil Seawater Onsen”

The open-air bath overlooking the majestic Sea of Japan features a rare natural Onsen fed by ancient seawater known as “fossil seawater.” Long ago, seawater trapped deep underground matured over 300,000 years into this restorative spring. Rich in fossil seawater, it has a high salt content that helps retain warmth and moisture, so you stay comfortable longer after bathing—like a natural form of thalassotherapy (marine therapy).
