平清盛
Ata Tadakage's rise to power was seen as a rebellion by the central government, which was then controlled by Taira no Kiyomori. Around 1160, probably after the Heiji Rebellion, an imperial decree was issued to punish him. The punitive expedition was led by Taira no Iesada, a retainer of Taira no Kiyomori. Tadakage fled to an island named "Kikai-ga-shima". Due to high waves and strong winds, Iesada was unable to track Tadakage down, and he disappeared from history.
