Diplomatic relations between Canada and Japan were established on January 31, 1928. Canada's third legation abroad was established in Japan on January 18, 1929, in Tokyo with Herbert Marler as the first minister plenipotentiary to the country. The mission was downgraded in 1938 due to the worsening international situation with the Chargé d'affaires becoming the lead official. Diplomatic relations were severed and the embassy formally closed on December 7, 1941, after the Japanese attack on World War II. Following the war, Canada's mission in Tokyo was accredited to the Supreme Commander Allied Powers, with Egerton Herbert Norman appointed head of mission on July 7, 1946. After the peace treaty with Japan, diplomatic relations resumed, and the mission upgraded to an embassy on March 18, 1950, with the first ambassador Robert Wellington Mayhew appointed on September 25, 1952.
