Sanko Shrine is located on a small hill south of Tamatsukuri (formerly Himeyama). Its three deities, Amaterasu Omikami, Tsukuyomi-no-Mikoto, and Susanoo-no-Mikoto, have long been known as gods of protection against paralysis. A grand festival for protection against paralysis is held annually, beginning on June 1st, for seven days. The subordinate shrine, Takeuchi no Sukune, is enshrined as the god of wealth and longevity, and is a constant source of worship as Jurojin, one of the Seven Lucky Gods of Osaka. On June 1, 1945, an air raid destroyed all the buildings, including the shrine buildings. However, thanks to the efforts of parishioners and worshippers, the shrine has been restored to its current state after the war. This area is believed to have been part of Sanadamaru, and it is said that an underground passageway to Osaka Castle, known as "Sanada's Loophole," was once built. Traces of this passageway remain, and the entrance is usually blocked by an iron gate. The statue of Sanada Yukimura, holding his baton high, was erected on May 5, 1987. The base is made of stone (Sanada stone) taken from Hasedera Temple, the family temple of the Sanada family in Ueda, Shinshu.
