Ikushina Shrine located in Nitta Ichinoi-cho, Ota City, Gunma Prefecture is a shrine pertaining to Nitta Yoshisada, a loyal retainer of Emperor Go-Daigo. The enshrined deities are Onamuchi no Kami, Homudawake no Mikoto, and Takeminakata no Kami. The shrine is listed on Jinmyocho (the list of deities made in the Heian period) but when it was founded is unknown. It is the main shrine of all the Ikushina shrines in the city.

It is said that Nitta Yoshisada raised his army in the precinct of this shrine before he made war against the Kamakura Shogunate under the order of Emperor Go-Daigo. There are a lot of remains pertaining to Yoshisada in the precinct including the statue of Nitta Yoshisada, the mound where Yoshisada raised his army, the place where he set his portable chair, the sawtooth oak tree on which he hung his troop flag and a stone monument.

On May 8th, the day when Yoshisada raised his army, Kaburaya Festival is held every year, in which local elementary school children launch arrows all together in the direction of Kamakura.
