Tokyo Detention House (Tokyo Prison) 東京拘置所

The only thing I know about Japan’s criminal justice system is its famously high 99% conviction rate.

It was only until I saw a strange shape on a map did I even notice that Tokyo actually has prisons.

This large, asterisk-shaped building, is the Tokyo Detention House (Tokyo Prison)  東京拘置所, located in Katsushika-ku 葛飾区, Tokyo (map).

Here is the prison from an aerial photograph (circa 1945-1950), and per a map from 1945. The prison is labeled Kosuge Prison 小菅刑務所, the old name for this facility.

On the grounds of the prison are the Kosuge palace ruins 小菅御殿跡, the location of a hunting and falconry grounds during the Edo times (source).
