It is said that Prince Shotoku built this shrine on Chausuyama in memory of his uncle, Emperor Sushun, the 32nd emperor, at the same time as Shitennoji Shitennoji was built during the reign of Empress Suiko, the 33rd emperor of Japan. It is one of the Shitennoji Seven Shrines. From ancient times until the mid-Meiji period, there was a beautiful moat along the south side of the temple grounds, and it is said that the name "Horikoshi" was given to the shrine because people would cross this moat to visit the temple. The shrine grounds enshrine Prince Kubotsu, the first prince of Kumano, who once lived in Watanabenotsu, Hachikenya. Although it faces the busy Tanimachi-suji street, the grounds maintain a tranquil atmosphere thanks to trees that are hundreds of years old. In Osaka, there is a legend that "Horikoshi-san is a god who will grant your once-in-a-lifetime wish," and the shrine has been loved for a long time.
