Surrounded by pristine nature, it is loved by many climbers and tourists as a representative secret hot spring resort in Hokkaido, where visitors can enjoy spectacular scenery throughout the four seasons and high-quality hot spring water.
This article comprehensively introduces information you should know when visiting Asahidake Onsen, including its attractions, spring quality, access methods, recommended accommodation facilities, surrounding tourist spots, and climbing information.
What is Asahidake Onsen? Its History and Characteristics
History of Asahidake Onsen
The history of Asahidake Onsen is relatively recent, with full-scale development as a hot spring resort beginning after the 1950s. Before that, there were only mountain lodges for climbers, but with the opening of the Asahidake Ropeway (1958), development as a tourist destination progressed.
Today, it has become a hot spring resort visited year-round by numerous tourists as a base for Asahidake climbing and as a gateway to Daisetsuzan National Park.
Mountain Hot Spring Area Spanning 1,100m Elevation
The greatest characteristic of Asahidake Onsen is its high elevation. Because it is located at approximately 1,100m elevation, it features a cool climate and clear air different from the plains. Even in summer it is cool and is popular as a summer retreat.
The hot spring village is small-scale, with several hot spring inns scattered about, creating a quiet atmosphere. Unlike large resort areas with bustling crowds, you can fully experience a sense of unity with nature in this setting.
Asahidake Onsen’s Spring Quality and Benefits
Characteristics of the Spring Quality
The spring quality of Asahidake Onsen is primarily sulfuric spring (acidic – sulfur-containing – calcium/sodium – sulfate/chloride spring). The source spring temperature is approximately 50-70°C, with milky white water as a characteristic feature. The scent of sulfur fills the air, giving a genuine sense of “visiting a hot spring.”
The water color is milky white or bluish-white, with slight variations depending on the facility. This varies due to differences in sulfur component concentration, temperature, and contact time with air.
Expected Benefits
Sulfuric springs have long been known as “beauty waters,” and the following benefits are expected:
- Skin diseases (atopic dermatitis, chronic eczema, etc.)
- Rheumatoid arthritis
- Muscle pain and joint pain
- Neuralgia
- Cold sensitivity
- Fatigue recovery
- Arteriosclerosis
- Chronic women’s diseases
The sulfur components create a film on the skin surface with high heat retention effects, so warmth persists even after leaving the bath.
Precautions When Bathing
Since sulfuric springs have a strong stimulating quality, the following points require attention:
- Metal accessories may discolor, so remove them before bathing
- Avoid prolonged bathing (about 10-15 minutes per bath)
- Those with sensitive skin should lightly rinse with shower after bathing
- Drinking the spring water is not possible in most facilities (due to strong acidity)
