Nanki Shirahama, a Historic Hot Spring Resort on the Kii Peninsula

Shirahama Onsen is one of Japan's oldest hot springs, along with Arima and Dogo Onsen. It is mentioned in ancient texts like the Manyoshu and Nihon Shoki and has been visited by emperors such as Emperor Saimei and Emperor Tenchi. This renowned onsen destination offers various hot spring experiences, including ryokan baths, outdoor public baths, and foot baths.

With its 1300 years of history, it is not only famous as a hot spring cluster town, but also as a prime beach resort in West Japan, due to its unique, white sandy half-moon shaped beach. The origins of the hot spring source are not clear since there is little volcanic activity in the area. Shirahama Onsen invites you to experience its historical charm, diverse hot springs, and beautiful natural scenery throughout the year.
