The Battle of Oshikibata (折敷畑の戦い, Oshikibata no tatakai) was a preliminary round of the battle of Miyajima which was to follow. Mōri Motonari sought to avenge Sue Harukata's coup against their lord, Ōuchi Yoshitaka, and succeeded.
Following the battle of Miyajima, the Mōri clan gained all the Ōuchi lands, and replaced them as one of the most powerful families in the country.
