Yoshinori held Zeami's nephew Onnami in high regard, and disagreed with Zeami's refusal to declare Onnami his successor as leader of his troupe. Possibly due to this disagreement, though a variety of competing theories have been advanced, Yoshinori sent Zeami into exile to Sado Island. After Yoshinori's death in 1441, Zeami returned to mainland Japan, where he died in 1443.
