The Invasion of Shikoku (四国平定, Shikoku heitei) was a conflict of the Sengoku period of Japan fought between Toyotomi Hideyoshi and Chōsokabe Motochika on the island of Shikoku in 1585. Hideyoshi invaded Shikoku with a force of over 100,000 men in June and led a campaign against the Chōsokabe clan force of 40,000 men for control over the island. Hideyoshi's army was successful and conquered most of Shikoku within two months, and defeated Chōsokabe when he surrendered Ichinomiya Castle in August.
