Hachimantai Onsen-go — relief & relaxation | Compare & book inns

Overview

Hachimantai Onsen-go is a collective term for the hot spring areas within Towada-Hachimantai National Park, straddling the border of Iwate and Akita prefectures. At altitudes exceeding 1,000 meters, you'll find a scattering of onsen with their own unique sources and histories, including Fujishichi Onsen, Fukenoyu Onsen, Goshogake Onsen, and the renowned Tamagawa Onsen, known for having the most acidic spring water in Japan.

Blessed by volcanic activity, the region boasts an abundance of hot water with a wide variety of mineral compositions. It has long been cherished as a 'toji' (hot spring cure) destination, attracting visitors for therapeutic bathing and health promotion. Hachimantai offers unique bathing experiences that let you feel the raw power of nature, such as mud baths, steam baths, and geothermal rock saunas. Rejuvenate your mind and body amidst stunning scenery of beech forests and alpine flora.

Iconic Spring Types and Benefits

The most distinctive feature of Hachimantai Onsen-go is its unique spring types: sulfur and acidic. Sulfur springs, with their characteristic aroma and milky-white water, are said to promote silky skin by improving circulation and softening the skin. Acidic springs, on the other hand, have strong sterilizing properties and are believed to be beneficial for various skin conditions. As each facility has different water, onsen-hopping is a great way to enjoy the area.

• Atopic dermatitisThe sulfur springs found here are known to promote blood circulation and are said to have a detoxifying effect. These actions may help alleviate the chronic inflammation and itching common with this skin condition.
• Psoriasis vulgarisThe circulation-boosting effects of sulfur springs may help improve nutrient delivery to affected skin areas. This is thought to be beneficial in managing the inflammation and rapid skin cell buildup associated with psoriasis.
• Chronic eczemaThe hydrogen sulfide in sulfur springs is believed to dilate capillaries and improve circulation. This enhanced blood flow to the skin may help manage persistent inflammation and support the skin's natural healing process.
• Dry skin
• Diabetes mellitus
• Poor peripheral circulation

Water Characteristics and Best Seasons

Many establishments offer 'gensen kakenagashi'—baths fed by a continuous flow of pure, high-temperature spring water. The waters vary in appearance and feel, from cloudy sulfur baths to tingling acidic ones. There are also many facilities geared towards long-term stays for 'toji', allowing you to fully immerse yourself in the onsen's benefits.

The best times to visit are from late May to June for the brilliant fresh green foliage, and from late September to mid-October for the spectacular autumn colors that paint the mountainsides. While some roads close in winter due to heavy snowfall, an outdoor bath surrounded by a snowy landscape ('yukimi-buro') is an exceptionally magical experience. The cool highland climate also makes it a popular summer retreat.
