The surrender of Imperial Japan was announced by Japanese Emperor Hirohito on August 15 and formally signed on September 2, 1945, bringing the hostilities of World War II to a close.
Interestingly, on the official document, Canada signed in the wrong place, forcing every subsequent country to have to manually re-write their country. If you look closely you may notice that the “Dominion of the Netherlands Representative” made a typo, writing “Representive” instead.
