This Engishiki Myojin Taisha shrine is said to have originated as a shrine dedicated to Ikushima-no-kami and Tarushima-no-kami at Ishiyamazaki (near present-day Osaka Castle). It was burned down during the Ishiyama War in 1580, but was relocated to its current location in 1583 when Toyotomi Hideyoshi built Osaka Castle. The main hall was built two years after the relocation, and features a single Nagare-zukuri roof for the main hall and offering hall, with three gables on the front - a chidori-hafu, a sugari-karahafu, and a chidori-hafu - in the Ikukunitama-zukuri style, which is unprecedented in the history of shrine architecture. The current main hall was rebuilt after the war with a concrete structure and copper-roofed roof, but it is said to retain remnants of the Momoyama period. Every year on June 30th, the Great Purification Ceremony is held to ward off disasters and illnesses, the Ikutama Summer Festival is held on July 11th and 12th, the Osaka Firewood Noh performance is held on August 11th and 12th, and the Hikohachi Festival, named after Yonezawa Hikohachi, the founder of Kamigata Rakugo, is held on the first Sunday of September and the day before, and the shrine is bustling with visitors.
