The Tokyo Detention House (東京拘置所, Tōkyō Kōchisho) is a correctional facility in Katsushika, Tokyo.[1][2] The prison, which is operated by the Ministry of Justice, is one of seven detention centres that carry out executions in Japan. It is used to detain people awaiting trial, convicted felons and those sentenced to death. In April 2019, the Special Security Response Team, a tactical response unit, was established at the TDH.[3]
One of Japan's seven execution chambers is in this facility. All executions in Japan are carried out by hanging. The execution chamber in Tokyo has a trap door, which is operated by one of the three buttons in the next-door room, which are simultaneously pressed by three prison staff members so that none of them will know who activated the drop.[4]
Before entering the execution chamber, the condemned person passes a Buddhist statue of Kannon (観音), a bodhisattva associated with compassion.[4] The execution chamber has two sections, with both of them together no larger than a 15-tatami mat room.[2] When the execution happens, the body drops into a room below the execution chamber; it is in this room where death is confirmed.[5]
