Jugo Mansai was born in 1378. He was the son of Imakoji Morofuyu, a member of the aristocracy.
He became a monk at the Daigo-ji near Kyoto and in 1395 advanced to the highest position among the monks.
Mansai enjoyed the profound trust and respect of Shogun Ashikaga Yoshimitsu, who made him his yushi, or adopted son without inheritance rights.
In return Mansai assisted both Yoshimitsu and his successois, the shoguns Yoshimochi and Yoshinori, in the management of government affairs. Mansai was a conscientious diary keeper, and the sections dealing with the years from around 1411 to 1435 have been preserved. Describing such events as the peasant uprising in the province of Omi in 1428 and the struggle for power that preceded the selection of Yoshinori as shogun, it is one of the primary sources for the history of the period.
In 1428 Mansai was given the honorary title jugo, indicating that he was entitled to the same respect due to a consort of the imperial family, and is hence known as Mansai Jugo.
