In the Insei system, the monarch abdicated or retired and a new emperor was named; however, the old emperor held on to significant power and influence in the court and in the nation. The emperors who withdrew from public life did not give up any of their many powers. In practice, the retired emperor only gave up the time-consuming burden of his ceremonial roles and formal duties.
