An annual festival at this shrine close to Akasaka-Mitsuke Station in celebration of the renowned middle Edo period samurai, judge and feudal lord Ooka Tadasuke.

Ooka is celebrated in many tales still popular today for being an incorruptible magistrate and also for forming the first citizen fire brigade as well as founding a hospital for the destitute.

As is quite common in the Shinto religion, great historical figures are deified and worshipped.
