In December, 1958, Sugamo Prison was closed, all remaining prisoners being freed. In 1971, the prison complex, covering six acres, was sold to the Japan Urban Development Company for 17.7 million US dollars and then demolished. On the site now stands the 'Sunshine City' shopping centre, including a sixty-storey sky scraper. In a corner of the complex is a small park on which stands a large stone placed on the site of the former gallows. The inscription on the stone reads "Pray for Eternal Peace."
