This Engishiki Meishin Taisha Shrine is said to have its origins in Ikushima-no-kami and Tarushima-kami at Ishiyamazaki (near present-day Osaka Castle). It was destroyed by fire during the Battle of Ishiyama in 1580, but was moved to its current location in 1583 when Toyotomi Hideyoshi built Osaka Castle. The main hall was built two years after the relocation, and the main hall and the hall were roofed with a single piece of driftwood, and three gables were installed in the front: a chidori gable, a sagari kara gable, and a plover gable, which is unprecedented in the history of shrine architecture. The Ikkoku Tamazukuri style is used. The current main shrine was rebuilt after the war and is made of concrete and has a copper plate roof, but it is said to retain the remains of the Momoyama period. Every year on June 30th, there is the ``Great Purification Ceremony'' to ward off misfortune and illness, on July 11th and 12th the ``Ikutama Summer Festival'', on August 11th and 12th the ``Osaka Takigi Noh'', and in September The Hikohachi Festival, named after Hikohachi Yonezawa, the founder of Kamigata Rakugo, is held on the first Sunday and the day before, and is crowded with many worshipers.
