Oushiko Shrine quietly stands in the back hills of a quiet residential area in Takasago City, Hyogo Prefecture. This shrine is a hidden power spot, and its sacred object is a giant stone structure weighing 500 tons that is said to float on water. This offering is a set of two items: a goshuin (red seal stamp) and a written explanation of the shrine's history. The shrine's sacred object is called "Ishino-Hoden" (Stone Treasure Hall), and it is also known as "Ukishi" (Floating Stone) because it appears to float on the water's surface. It is one of Japan's three great wonders (along with the Shiogama Shrine's Shiogama and Kirishima Jingu Shrine's Ama no Sakahoko). It is unknown when or why it was built. The shrine is said to have been founded during the reign of Emperor Sujin (around 97 AD) and is designated as a national historic site.
