Overview
Mentioned in the ancient chronicles Nihon Shoki and Man'yoshu, Shirahama stands alongside Arima and Dogo as one of Japan's Three Ancient Hot Springs. Once known as "Muro-no-yu," it has been a cherished destination for emperors and courtiers for balneotherapy since the Asuka and Nara periods.
A key feature is the variety of hot spring sources scattered along the coast, perfect for onsen-hopping. The area has evolved into a leading Japanese resort, offering everything from modern hotels to traditional ryokan inns. Its beautiful Shirarahama Beach, with its pure white sand, throngs with beachgoers in summer.
Main Spring Types & Benefits
Shirahama's primary waters are salt-rich "Chloride springs" (塩化物泉) and skin-smoothing "Bicarbonate springs" (炭酸水素塩泉). Chloride springs are known for a lasting warming effect that prevents post-bath chills. Bicarbonate springs, often called "waters for beautiful skin," are said to cleanse the skin by washing away old cells and impurities, leaving it feeling smooth.
- CutsThe salt content in chloride springs, common in Shirahama, has disinfecting properties that can help cleanse minor wounds. Improved blood circulation from bathing also supports the body's natural healing process, and the mineral-rich water may aid in the recovery of small skin abrasions.
- Sensitivity to coldThis condition is often addressed by the heat-retaining properties of Shirahama's chloride springs. The salt in the water forms a thin layer on the skin, which prevents post-bath chills and helps the body stay warm. This lasting effect may alleviate a persistent feeling of coldness.
- Dry skinShirahama's waters, particularly the bicarbonate springs, are known as "waters for beautiful skin" for their ability to soften and smooth the skin. Additionally, the salt from chloride springs forms a moisturizing veil that helps prevent the skin from drying out after your bath.

- Gastrointestinal hypofunction
Water Characteristics & Best Season
With numerous sources and an abundant flow, many facilities offer fresh, free-flowing hot springs (kakenagashi). Water temperatures vary widely from 32°C to 85°C. The mild climate makes it a pleasant year-round destination, but summer is great for swimming, while autumn and winter offer spectacular sunset views over Engetsu Island.
