The Insei system (院政), or cloistered rule, was a specific form of government in
Japan, in which the
Emperor abdicated, but kept exerting power and influence. Retired emperors are called
Daijō Tennō or Joko. Choosing to enter a buddhist monastic community, a retired emperor would become a
Daijō Hōō (太上法皇) or cloistered emperor.
