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. 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.
