The bakufu revised Buke Shohatto (Kanbunrei) in 1663, and forbade junshi (following one's master to the grave) and abolished the system of Shoninnosei (forcing daimyo to offer a hostage) (these two measures were called 'two good actions in the Kanbun era').
1663年武家諸法度を改正（寛文令）し、殉死を禁止し、大名からの人質を出す証人の制を廃止した（これを寛文の二大美事という）。
