Sukayu Onsen — relief & relaxation | Compare & book inns

Overview

Sukayu Onsen is a single-inn hot spring resort located at an altitude of about 900 meters in the Hakkoda Mountains of Aomori Prefecture. Its history dates back to 1684 in the early Edo period. It was originally named "Shika-no-yu" (Deer's Bath) after a deer was seen healing its wounds in the spring.

In 1954, in recognition of its excellent therapeutic properties and rich natural environment, it became the first hot spring in Japan to be designated as a National Hot Spring Health Resort. The culture of "toji" (hot spring healing), which focuses on the curative power of the springs, is still very much alive, with many visitors staying for extended periods for physical and mental recuperation. The area is also known for its extremely heavy snowfall, offering a magical snow-viewing bath experience in winter.

Spring Quality & Benefits

The water is classified as an "acidic, iron- and sulfur-containing, aluminum-sulfate-chloride spring," characterized by its strong acidity with a pH below 2.0. The milky-white water has a distinct sulfur smell and is said to have high sterilizing properties. This potent water quality has long been sought after to help with various skin conditions.

• Atopic dermatitisThe spring's strong acidity provides a sterilizing effect, which is traditionally said to be beneficial for skin diseases. This action may help soothe the inflammation and irritation associated with atopic conditions.
• Psoriasis vulgarisThe water's highly acidic and sulfurous properties are believed to help manage chronic skin conditions. Its sterilizing effect may assist in alleviating the symptoms of psoriasis, a long-standing indication for this onsen.
• Chronic eczema
• Impaired glucose tolerance (Diabetes)Bathing in sulfur-rich springs is a traditional therapy for this indication in Japan. The minerals in the water are thought to have a beneficial effect on the body's metabolic functions, which may help regulate blood sugar levels.
• Peripheral circulatory disturbanceThe thermal properties of the hot spring water can help improve blood flow throughout the body. This warming effect promotes vasodilation, which can enhance circulation to the extremities and ease related discomfort.

Water Characteristics & Best Season

The symbol of Sukayu Onsen is the "Hiba Senninburo" (Thousand-Person Cypress Bath), a grand bathhouse made entirely of Hiba cypress. The vast, 265-square-meter space is completely pillar-less and features baths of different temperatures. All baths are fed by free-flowing water directly from the source. Soaking in the milky water offers a true escape from the hustle and bustle of daily life.

The best times to visit are early summer (June-July) when the beech forests are a vibrant green, or autumn (late September to mid-October) when the Hakkoda Mountains are ablaze with color. While winter brings heavy snow, a quiet bath while gazing at the snow-covered landscape is an exceptional experience. However, be sure to check road conditions in advance, as access can be limited during winter.
