Saki-no-Yu Onsen is located in Shirahama, Wakayama Prefecture, and is known as one of Japan’s oldest seaside hot springs. Its open-air baths are built directly into the rocky coastline, allowing bathers to experience the sight and sound of waves crashing against the shore while soaking in naturally heated waters.
The mineral-rich waters are divided into gender-separated baths, each offering uninterrupted views of the Pacific Ocean. With over a thousand years of history, the onsen holds cultural significance and continues to attract visitors for its connection to the region's past.
