Overview

Located in Oda City, Shimane Prefecture, Yunotsu Onsen boasts a long history dating back approximately 1,300 years. It once flourished as a therapeutic spa for workers of the Iwami Ginzan Silver Mine, a World Heritage site. Remnants of this past can still be seen throughout the hot spring town. The road leading from the port to the onsen district is a designated Important Preservation District for Groups of Traditional Buildings, welcoming visitors with its sepia-toned townscape.

At the heart of the town are two public bathhouses: 'Motoyu Senyakuto' and 'Yakushiyu'. Motoyu retains the atmosphere of an old-fashioned therapeutic bath, and its hot water warms you to the core. In contrast, Yakushiyu, with its retro-modern, Western-style building, is known as a premier hot spring, having received a perfect 'All 5' rating from the Japan Onsen Association. Hopping between these two baths with different water qualities is a unique pleasure of Yunotsu.

Key Spring Qualities and Health Benefits

The main spring quality at Yunotsu Onsen is 'Chloride Spring,' which contains components similar to seawater. The salt in the water coats the skin, preventing the body from cooling down after bathing, earning it the nickname 'Netsu no Yu' (Water of Warmth). Motoyu, in particular, is one of the most highly concentrated chloride springs in Japan and has been beloved by many for its potent therapeutic effects.

  • Poor peripheral circulation
  • Sensitivity to cold
  • Dry skin
  • Rheumatoid arthritis
  • Weak gastrointestinal function

Water Characteristics and Best Season to Visit

The source temperature is very high, ranging from 45 to 49°C (113-120°F), and the water is served 'gensen-kakenagashi'—flowing directly from the source without any added water, heating, or circulation. As the mineral content is extremely high, be careful not to over-bathe, as it can be overwhelming. It's recommended to acclimate your body with 'kakeyu' (scooping and pouring hot water on yourself) and practice 'bunkatsuyoku' (split bathing) by taking short dips in and out of the tub.

The nostalgic atmosphere of the onsen town can be enjoyed year-round, but the best season is from autumn to winter when the seafood from the Sea of Japan is at its most delicious. You can also have the precious experience of witnessing 'Iwami Kagura,' a traditional sacred dance, performed at a local shrine in the evening.
