After the death of Yoshimitsu, his successor Ashikaga Yoshimochi was less favorable to Zeami's drama. Zeami successfully sought out patronage from wealthy merchants and continued his career under their support. He became well-known and well-respected in Japanese society. Ashikaga Yoshinori became hostile toward Zeami after becoming Shōgun in 1429. 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.
