Japan’s Surrender Day, also known as Victory over Japan Day, is observed worldwide every September 3 to commemorate the surrender of Imperial Japan in World War II. The day marks the signing of the surrender document aboard the USS Missouri in Tokyo Bay on September 2, 1945, following Emperor Hirohito's announcement of Japan's acceptance of the Potsdam Declaration on August 15. Various countries have their own observances related to Japan's defeat, with some celebrating on different dates, such as August 15 in several Allied nations. In mainland China and Hong Kong, September 3 is celebrated as Victory over Japan Day, while in the Philippines, it is known as Yamashita’s Surrender Day, named after General Tomoyuki Yamashita, who was the Japanese military governor during the occupation. The day has historical significance in Taiwan as Armed Forces Day, and it was declared a special working holiday in the Philippines in 2019.
