Myoken Onsen — relief & relaxation | Compare & book inns

Overview

Myoken Onsen is the central hot spring area of the "Shinkawa Keikoku Onsen-kyo," a collection of inns scattered along the Amori River in Kirishima, Kagoshima. Its history dates back to the Edo period, with records showing its use as a therapeutic spa, or toji-ba. This tradition continues today, with some inns still offering self-catering facilities for long-term balneotherapy stays.

The most distinctive feature of this onsen is the subtle variation in spring quality, color, and temperature from one source to another. Many springs are rich in carbon dioxide, offering a unique bathing experience where fine bubbles cling to your skin. This has earned them names like "Kizu no Yu" (Wound-Healing Waters) and "Icho no Yu" (Stomach Waters), attracting visitors seeking their reputed benefits.

Signature Spring Qualities & Benefits

The primary spring type is a sodium/calcium/magnesium bicarbonate spring, known as a "Bihada no Yu" (beauty-enhancing water) for its ability to exfoliate and leave the skin feeling smooth. The inclusion of chloride components provides a restorative warmth that helps the body retain heat long after bathing. The carbon dioxide also helps to improve circulation, aiding in physical and mental refreshment.

• CutsThe spring's properties, known for removing dead skin cells, may also help cleanse minor cuts. This gentle cleansing action can support the body's natural healing process.
• Poor peripheral circulation
• Sensitivity to coldBathing in the hot, mineral-rich water improves blood circulation throughout the body. This deep warming effect can help alleviate chronic feelings of coldness in the hands and feet.
• Dry skinMyoken's sodium bicarbonate saline springs are famously known as "baths for beautiful skin." The water helps to gently exfoliate and remove old keratin, leaving the skin feeling smooth and supple.
• Reduced gastrointestinal function

Water Characteristics & Best Season

Source temperatures vary from 40°C to 60°C (104°F to 140°F). Many establishments pride themselves on offering gensen kakenagashi—pure, fresh onsen water flowing directly from the source without added water or heating. The water is so plentiful that some inns even offer it for drinking. Some springs, rich in iron, emerge clear but turn a reddish-brown color upon contact with the air.

While enjoyable year-round, the best seasons to visit are autumn (around November) when the trees along the river valley display their vibrant colors, and spring (April-May) when the fresh green foliage is a beautiful sight. These times offer a perfect combination of scenic beauty and relaxing soaks.
