Ten'ei-in seized the opportunity of Ejima missing her curfew to launch an investigation of the Ōoku by the Machi-bugyō, with numerous infractions being discovered, and ultimately over 1,300 people were punished. Ejima was sentenced to death, but she received a pardon and was instead placed in custody of the Takatō Domain, while her brother was sentenced to die not by seppuku (which is an honoured death under Bushido), but by zanshu (beheading, which was more suited for a regular criminal). Ikushima was banished to the island of Miyake-jima and the Yamamura-za was disbanded, with its owner being banished to the island of Izu Ōshima.
