Toyotomi Hidetsugu
Hideyoshi attempted to provide for an orderly succession by taking the title "taikō", or "retired Kanpaku (Imperial regent)", in 1591, and turned the regency over to his nephew and adopted son Toyotomi Hidetsugu. Only later did he attempt to formalize the balance of power by establishing administrative bodies. These included the Council of Five Elders, who were sworn to keep peace and support the Toyotomi, the five-member Board of House Administrators, who handled routine policy and administrative matters, and the three-member Board of Mediators, who were charged with keeping peace between the first two boards.
