In 1988, the historian Kasaya Kazuhiko published Shukun “oshikome” no kōzō, The Structure of the Lord’s Confinement. It won the Suntory Prize for Social Sciences and Humanities. The book describes oshikome, a practice of Edo-period domains.
When a lord ruled badly, his senior retainers agreed among themselves to confine him and give him time to reform. If he did not, they retired him and installed another lord. The prize citation notes that the practice was widely accepted as legitimate and was usually carried out peacefully.
