Minamoto no Yoriie
In 1199, Yoritomo died, and Rokudai was arrested at his home in Nijo Inokuma, and exiled to Oki province. He is charged of treason, for planning an attack (known as the Incident at Sansaemon) on Minamoto no Yoriie, son of the former shogun. A few months later he was executed at Tagoshi River.
