The Japanese martial art and combat sport judo has been practised in Canada for over a century. The first long-term judo dojo in Canada, Tai Iku Dojo, was established by a Japanese immigrant named Shigetaka "Steve" Sasaki in Vancouver in 1924. Sasaki and his students opened several branch schools in British Columbia and even trained RCMP officers until 1942, when Japanese Canadians were expelled from the Pacific coast and either interned or forced to move elsewhere in Canada due to fears that they were a threat to the country after Japan entered the Second World War. When the war was over, the government gave interned Japanese Canadians two options: resettle in Canada outside of the 'Japanese exclusion zone' or emigrate to Japan.
