Shirahama Sakura Onsen

Shirahama Sakura Onsen is one of Japan's oldest thermal resorts, situated in Shirahama town on the Kii Peninsula of Wakayama Prefecture, where siliceous hot springs have been documented since the 7th-century Nihon Shoki chronicle alongside the famous Shirahama white-sand beach — one of Japan's most beloved coastal destinations. The siliceous waters of Shirahama are particularly celebrated for producing exceptionally smooth and moisturized skin, attracting generations of Japanese visitors seeking the rare combination of oceanside relaxation and therapeutic hot spring bathing. Shirahama's unique pairing of pristine white sand beach, clear blue Pacific waters, and ancient siliceous onsen culture makes it one of Japan's most beloved resort destinations, where Wakayama's subtropical coastal atmosphere meets a thermal tradition stretching back nearly 1,400 years.
