Shirahama Onsen 白浜温泉
Shirahama Onsen is located on the west coast of the Kii Peninsula across the bay from Tanabe and is one of the oldest hot springs in Japan. Shirarahama beach is a highlight of the area. This developed resort village features onsen baths in dozens of accommodations as well as public facilities.
One of the most popular hot spring baths is called Sakino-yu, located north of the beach area. It is a quaint open-air bath carved into a rocky, wave beaten shoreline overlooking the ocean.
