The Suzugamori execution grounds (鈴ヶ森刑場, Suzugamori keijō) were one of many sites in the vicinity of Edo (the forerunner of present-day Tokyo, Japan) where the Tokugawa shogunate executed criminals, anti-government conspirators and Christians in the Edo period. Others sites included Shibaguchi, Honzaimokuchou, Itabashi, near the Torigoe Myoujin shrine, in front of Saihouji in Kondobashi, and Kotsukappara.[1] The Suzugamori grounds were established in 1651 and operated until 1871. During this 220 year time period, an estimated 100,000 people were executed at Suzugamori.[2]
