Kin no Yu Onsen

Kin no Yu is a historic public bathhouse located in the heart of Arima Onsen, Kobe—one of Japan’s oldest and most renowned hot spring towns. This facility is celebrated for its distinctive “kinsen” or “golden waters,” which emerge clear but oxidize to a rich amber hue due to high concentrations of iron and salt. These mineral-rich waters are believed to offer therapeutic benefits, including relief from muscle and joint pain, improved circulation, and skin nourishment.

Inside Kin no Yu, visitors will find two indoor baths of varying temperatures (approximately 42°C and 44°C), allowing guests to choose their preferred level of warmth. The bathhouse provides essential amenities such as shampoo and shower gel, and it is known to be tattoo-friendly, welcoming a diverse range of guests.

Adjacent to the main facility is a free foot bath (ashiyu), perfect for a brief, relaxing soak while exploring the town.
