Shirahama Onsen

Located on the west coast of the Kii Peninsula across the bay from Tanabe, Shirahama Onsen is one of the oldest hot springs in Japan together with Arima Onsen and Dogo Onsen. The Onsen is famous for not only 1300 years long history but also the well-balanced nature of gentle breeze, blue ocean and beautiful beach thanks to the position of resort facing the Pacific Ocean over a hot flow.
Shirahama onsen
Shirahama Onsen used to be called Muro hot spring in the Asuka period and Ki hot spring in the Nara period. It was even mentioned in ancient books such as The Chronicles of Japan, Records of Wind and Earth or Collection of a Myriad Leaves which were written in the 8th century. According to those books, famous Japanese Emperors including Mombu, Saimei, Tenchi and Jitto along with the members of their courts came here. It is quite easy to understand because texture and mineral substances of Shirahama are distinctive around Japan. There is no any volcano in the area and the origin of the hot stream is a mystery.

Sakiyu is one of the most popular hot spring bath located in the north of the beach area, 10 meter from the shore. It is an open air bath lying on rock shoreline which is carved by waves and looking right out on the vast Pacific ocean. From this unique onsen, you will not only watch the waves striking the rocks but also feel the sea spray from the waves covering the whole onsen like a fairy scene. . It is said that Tokugawa Yoshimune, the ruler of Kii and later the eighth shogun of the Tokugawa shogunate, took a bath here. Shirasuna is an other noticeable open air onsen in Shirahama with the capacity of about 100 people of both genders.
