The Kibi Clan Rebellion (吉備氏の乱, kibishi no ran) from 463 was a revolt against the Yamato state on the Korean peninsula, involving two brothers from the : Tasa and Oto. The revolt was triggered when Tasa learned that the Japanese Emperor Yūryaku had moved him to the Japanese post at Mimana on the Korean Peninsula in order to seize his beautiful wife. The incident falls into Japan's proto-historic period and is recounted in the Nihon Shoki.
