太田神社, Shinto shrine in Ota, Ibaraki, Osaka, Japan

Ota Shrine is a Shinto shrine in the Ota 3-chome district of Ibaraki, Osaka Prefecture. It is a former village shrine (sonja) listed in the Engishiki register of shrines as receiving a hoe and quiver at the Kinen-sai festival. It stands directly beside the Ota Chausuyama Kofun, the tomb mound attributed to Emperor Keitai. Its precinct includes Tenjinsha, dedicated to Sukunahikona, and Inarisha, dedicated to Uka-no-Mitama.

The shrine is connected to ancient burial mounds in the area, suggesting a long history. Its exact founding date remains unclear, but it has served the community as a place of prayer for generations.

The shrine takes its name from the local area and has long been venerated by the community. During festival seasons, the grounds come alive with visitors coming to pray and participate in traditional rituals together.

The shrine stands at 3-15-1 Ota, Ibaraki, Osaka, next to the Ota Chausuyama Kofun, the tomb attributed to Emperor Keitai. The precinct is small and flat, with the Tenjinsha and Inari shrines inside the grounds. The site is reached on foot through the surrounding Ota neighbourhood.

The shrine stands next to Ota Chausuyama Kofun, a keyhole-shaped mound identified as the tomb of Emperor Keitai (Mishima no Aino no Misasagi). Archaeologists now consider the true Keitai tomb to be Imashirozuka Kofun to the northeast, leaving the identity of the person buried here an open question.
