Overview
Located in Tanabe City, Wakayama Prefecture, Yunomine Onsen was reportedly discovered 1,800 years ago. Situated along the Nakahechi route of the Kumano Kodo pilgrimage trails leading to Kumano Hongu Taisha Grand Shrine, it has historically played a vital role for pilgrims to cleanse themselves. The onsen town itself is a rare example of a designated World Heritage site.
In the center of the town is the 'Yuzutsu,' where natural hot spring water gushes out at over 90°C (194°F). The sight of locals and tourists boiling eggs and vegetables in this spring is a charming, characteristic scene of Yunomine Onsen. The 'Tsuboyu' bath, famous for being the only bathing hot spring registered as a World Heritage site, is a rustic bath in a small rocky hollow. It is said that its water changes color seven times a day, adding to the mystique that continues to attract visitors.
Main Mineral Qualities and Health Benefits
The water at Yunomine Onsen is a 'Sulfur-Sodium-Bicarbonate/Chloride Spring,' characterized by its distinct sulfur aroma. Sulfur springs are known for improving blood circulation and detoxification, while bicarbonate springs are famous as 'bijin-no-yu' (waters of beautiful skin) for their skin-smoothing properties. The water is also potable and is believed to benefit gastrointestinal functions and lifestyle-related diseases.
- Rheumatoid arthritis
- Gastrointestinal dysfunction
- Cuts
- Poor circulation
- Dry skin
- Impaired glucose tolerance (Diabetes)
- Hyperuricemia (Gout)
Water Characteristics and Best Season to Visit
The source temperature is extremely high at around 92°C (194°F), so most facilities add cool water to regulate the temperature. However, many baths are still fed by a free-flowing source (gensen kakenagashi). Due to the sulfur content, the water's color can change daily, appearing milky white or bluish. Visitors can enjoy the sulfur scent and the smooth, moisturizing feel of the water on their skin.
For those combining their visit with a hike on the Kumano Kodo, the best seasons are spring (April-May) and autumn (October-November) when the weather is pleasant. Summer offers deep green scenery, while winter provides a tranquil, atmospheric onsen experience, making it a wonderful destination year-round.
