The Pacific War, sometimes called the Asia-Pacific War, was the theater of World War II that was fought in the Pacific and East Asia. It was fought over a vast area that included the Pacific Ocean and islands, the South West Pacific, South-East Asia, and in China. The Pacific War saw the Allied powers pitted against the Empire of Japan, the formal and official surrender of Japan took place aboard the battleship USS Missouri in Tokyo Bay on 2 September 1945. In Allied countries during the war, The Pacific War was not usually distinguished from World War II in general, or was known simply as the War against Japan. Japan used the name Greater East Asia War, as chosen by a decision on 10 December 1941. Japanese officials integrated what they called the Japan–China Incident into the Greater East Asia War, in Japan, the Fifteen Years War is also used, referring to the period from the Mukden Incident of 1931 through 1945. The Phayap Army sent troops to invade and occupy northeastern Burma, also involved were the Japanese puppet states of Manchukuo and Mengjiang, and the collaborationist Wang Jingwei regime. The official policy of the U. S. Government is that Thailand was not an ally of the Axis, Japan conscripted many soldiers from its colonies of Korea and Formosa. To a small extent, some Vichy French, Indian National Army, Germany and Italy both had limited involvement in the Pacific War. The German and the Italian navies operated submarines and raiding ships in the Indian, the Italians had access to concession territory naval bases in China, while the Germans did not. After Japans attack on Pearl Harbor and the subsequent declarations of war, mexico, Free France and many other countries also took part, especially forces from other British colonies. Between 1942 and 1945, there were four main areas of conflict in the Pacific War, China, the Central Pacific, South East Asia, U. S. sources refer to two theaters within the Pacific War, the Pacific theater and the China Burma India Theater. However these were not operational commands, in the Pacific, the Allies divided operational control of their forces between two supreme commands, known as Pacific Ocean Areas and Southwest Pacific Area. In 1945, for a period just before the Japanese surrender. By 1937, Japan controlled Manchuria and was ready to move deeper into China, the Marco Polo Bridge Incident on 7 July 1937 provoked full-scale war between China and Japan. In August 1937, Generalissimo Chiang Kai-shek deployed his best army to fight about 300,000 Japanese troops in Shanghai, the Japanese continued to push the Chinese forces back, capturing the capital Nanking in December 1937 and committed which was known as Nanking Massacre. In March 1938, Nationalist forces won their first victory at Taierzhuang, but then the city of Xuzhou was taken by Japanese in May. In June 1938, Japan deployed about 350,000 troops to invade Wuhan, the Japanese achieved major military victories, but world opinion—in particular in the United States—condemned Japan, especially after the Panay incident
