In July 1930, the Imperial Legation of Iran in Tokyo was initially opened, but the diplomatic relations between Iran and Japan and the exchange of envoys extraordinary and minister plenipotentiary were suspended during the Second World War. After the war they were all resumed, and in February 1955, the Iranian highest mission in Tokyo was promoted from legation to embassy.[3] In February 1979, the Iranian monarchy was collapsed by the revolution; nevertheless, the diplomatic relations with Japan have been inherited and the Embassy of Iran in Tokyo has continued to this day without any suspension.[2]
