巣鴨拘置所
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 afoul of the Peace Preservation Laws in the 1930s and 1940s. Allied spies were also incarcerated there, including Richard Sorge who was hanged in the prison on November 7, 1944.
