Ikukunitama Shrine is an engishiki myojin grand shrine that had its beginning in worshipping Ikushima-no-kami and Tarushima-no-kami, located in Ishiyamazaki, the area of present-day Osaka. It is Osaka's oldest tutelary shrine which had its beginnings in prayers for nation-wide peace. There's the main shrine, hall of offerings, and in front of that is the hall of worship, corridors, and ceremonial rooms, etc. The existing buildings are all made from concrete, having been rebuilt after the war. It is said that Emperor Jinmu went to Ishiyamazaki during his easten expedition of the country to worship Ikushima-no-kami himself. In 1585, the shrine was moved to its present-day location due to Toyotomi Hideyoshi's construction of Osaka Castle. Unlike its current concrete construction, Ikukunitama Shrine was built using a unique style called Ikukunitama-zukuri. The five gate, four sided main shrine and the 7 gate, four sided hall of offerings were roofed in the style of Nagare-zukuri, and traditional contruction techniques were also used in the front portion of the roof. In 1871, the shrine was classified a Kanpei Taisha. Futhermore, it is also known for Ikukuni Tamamatsuri, following Ikutama, Temma, and Sumiyoshi, Osaka's big three summer festivals.
