Sugamo Prison was originally built in 1895, using the prisons of Europe as a model. By the 1930s it became known for housing political prisoners, including many communists and other dissenters who fell foul of the Peace Preservation Laws in the 1930s and 1940s. Alliedspies were also incarcerated there, including Richard Sorge who was hanged in the prison on November 7, 1944. The prison also was used to hold captured Allied officers during World War II as well as airmen.
The original compound was only 2.43 hectares (6.0 acres) in size. The construction of exterior fencing expanded the facility to double the original size. After being captured and re-purposed by Allied forces, the facility was operated by the United States’ Eighth Army. Under the U.S. occupation, Sugamo Prison was administered by 400–500 soldiers.[3] There were approximately 2500 military personnel assigned to duty at the prison, however no more than 500 at any given time. The prison was operated by occupation authorities from December 1945 through May 1952. The structure housed some 2000 Japanese war criminals during its operation.
The prisoners ate Japanese food prepared by Japanese personnel and served by the prisoners themselves. There were occasions when former Prime MinisterHideki Tojo served food to all the other class "A" prisoners. Some of the vegetables used in these meals were grown within the compound. On May 31, 1958, the last 18 Japanese war criminals still serving time in Sugamo Prison were paroled.[4]
After the end of the occupation of Japan, Sugamo Prison passed to Japanese civilian government control. Most of the remaining war criminals were pardoned or paroled by the government. In 1962 its function as a prison ended. In 1971 the prison buildings were dismantled.
In 1978, the Sunshine 60 Building, at its completion the tallest skyscraper in Japan, was built on the former site of Sugamo Prison. All that is left to commemorate the prison is a stone on which is engraved, in Japanese, "Pray for Eternal Peace." A water drainage outlet from the prison has been preserved in the park in front of the Tokyo International University Ikebukuro Campus, which stands on part of the former prison grounds.[5]
