  • I stayed in the hot-spring therapy Accommodation.The meals were also hot-spring therapy style, but very delicious—the seafood miso soup was outstanding.The staff were friendly and provided thorough explanations, and I was able to fully enjoy the Sennin Bath. I’d like to visit again in winter.

  • The Onsen was excellent, with nothing to complain about.The healthy hot pot dinner was very delicious.The property also had a charming atmosphere, but I could clearly hear noise from the hallway at night, which bothered me a little.

Hiba Sen'nin Bath (Japan's largest mixed-gender bathhouse)

The iconic "Hiba Sen'nin Buro" of Sukayu Onsen spans approximately 160 tatami mats and utilizes four distinct hot spring sources. There are two baths: "Netsu no Yu" and "Shibun Rokubun no Yu." "Netsu no Yu" is a hot spring where water wells up from beneath the bath, designed to maintain around 41°C through its depth and size. The warmth persists even after bathing, hence the name "Netsu no Yu." Inside the bathhouse, there is a Shinto altar, indicating that this onsen has been cherished for a long time.

Seasonal natural scenery and activities

The area surrounding the Sukayu Onsen is enveloped by beech trees, offering vibrant fresh greenery in spring, deep green hues in summer, and stunning autumn foliage in fall, providing a variety of scenic views. During winter, the breathtaking sight of frost-covered trees emerges. Uniquely for a Property with an Onsen, Sukayu Onsen employs nature guides as specialized staff. From summer to autumn, activities such as mountain climbing tours and historical and natural tours around the Hakkoda area are available, while in winter, guided backcountry skiing tours are offered, tailored to the season. Additionally, limited-time activities like autumn foliage viewing and apple picking are also held.

The Onsen Property with the most snowfall in Japan

Located in Towada-Hachimantai National Park, Hakkoda-Sukayu Onsen is also known as a heavy snowfall area. Snow begins to fall annually from late October, and in January and February, snow accumulation reaches about 3-4 meters, with fluffy powder snow attracting skiers from around the world. Spring skiing can be enjoyed until early May. The "Snow Corridor" between Sukayu and Yachi Onsen, which opens from April 1, is also a symbol of spring.

History and Tradition - The Inheritance of Hot Spring Culture -

About 300 years ago, an Onsen was discovered, and since then, many people have traveled from afar to visit for therapeutic bathing. Even as the culture of therapeutic bathing fades with the passage of time, this Property still accommodates long-term stays for such purposes and retains Facilities like communal kitchens for therapeutic bathing. Additionally, Sukayu Onsen is a place where Tatsugoro Shikanai, affectionately known as the "Hermit," worked for 60 years, contributing to mountain rescue operations and serving as a mountain guide. The world-renowned woodblock print artist Shiko Munakata also visited and his works are displayed within the Property. Furthermore, Keizo Miura, the honorary lifetime advisor of the "Association to Preserve Mixed Bathing Culture," and his son, Yuichiro Miura, both cherished and frequently visited Sukayu.

Notice from the Accommodation

  • Our autumn set menu is now available.

    Since last week, more days have seen highs below 20°C, and it’s starting to feel like autumn may arrive this year without any lingering summer heat.
    Although heavy rain has continued across Aomori Prefecture in recent days, Sukayu has avoided the kind of damage seen in lower-lying areas, and we are operating as usual as we welcome our guests. We sincerely hope there will be no harm to anyone and that crops nearing harvest, infrastructure, and daily life will not be affected.

    From Tuesday, September 15, our dinner set will switch to an autumn menu. Dishes featuring sweet potato tofu salad (shira-ae), Pacific saury, and Takekimi corn will add seasonal color to your meal—bringing you the flavors of an Aomori autumn. For those who would like even more seasonal specialties, we also offer recommended à la carte items such as Takekimi corn tempura and salt-grilled Pacific saury. Of course, we also have a wide selection of local sake—and this autumn we will be serving Houhai with a Sukayu original label from Miura Shuzo in Hirosaki City.

    Please take your time and enjoy Aomori’s autumn flavors at Sukayu Onsen together with the fall foliage of Mt. Hakkoda.

  • Hakkoda Community Center “Route” Now Open

    The former café “Buna-bayashi” inside Sukayu Onsen has been reborn as the Hakkoda Community Center “Ru-to.” Here, we introduce Hakkoda activities and Sukayu’s traditional hot-spring healing culture. We also serve Sukayu Blend Coffee (500 yen).

    “Ru-to” is named after the English word “Root,” meaning a presence like roots that invisibly connect people, nature, and the local community. Surrounded by Hakkoda’s rich natural environment, we hope this will be a place where Onsen bathing, therapeutic stays, activities, and交流 with others come together naturally, fostering new value and relationships.
