Yunohama Onsen — relief & relaxation | Compare & book inns

Overview

The discovery of Yunohama Onsen is said to date back to the Tenki era (1053-1058) in the mid-Heian period. Legend says it was found when an injured turtle was seen healing its wounds in the water, earning it the name "Kame-no-yu" (Turtle's Bath). Its prime location facing the Sea of Japan is its greatest feature, with many ryokans and hotels offering magnificent ocean views and beautiful sunsets.

The spring water, rich in salt, is called "Atsu-no-yu" (Waters of Warmth) because it keeps the body warm long after bathing. This excellent restorative warmth is believed to help promote blood circulation and relieve daily fatigue and muscle tension. Soaking in the onsen while feeling the sea breeze provides an experience of deep relaxation that liberates both mind and body.

Primary Spring Quality and Indications

The main spring type is a Sodium/Calcium-Chloride spring. Its composition is similar to seawater, and it tastes salty. When you bathe, the salt components adhere to the skin, forming a thin veil that prevents sweat from evaporating, resulting in high heat and moisture retention.

• Sensitivity to coldKnown as a "water of warmth," this spring is prized for its ability to prevent post-bath chills. The salt minerals form a coating on the skin that locks in body heat, providing lasting relief for those prone to feeling cold.
• Peripheral circulation disorder
• CutsThe high salt concentration in this chloride spring is thought to have a mild disinfecting effect. This property may help to gently cleanse minor scrapes and promote the body's natural healing process.
• Dry skinThe mineral-rich water forms a thin veil on the skin's surface, which helps to trap moisture. This natural barrier action can combat dryness, leaving your skin feeling hydrated and supple long after you leave the bath.
• Rheumatoid arthritis
• Decreased gastrointestinal function

Water Characteristics and Best Season

The source temperature is high, around 55°C (131°F), and the water volume is abundant. Many facilities offer baths with water flowing directly from the source (gensen kakenagashi). The water is clear, colorless, and has a slight salty taste, making it gentle on the skin and suitable for all ages. Summer is perfect for combining beach activities with onsen, while winter offers dramatic views of the rough Sea of Japan and snowy landscapes. The most beautiful time of day, year-round, is dusk, when the sky and sea are painted in brilliant orange.
