In this theater, Japan actually succeeded in carrying out swift, successful invasions of all of the colonies of the Asia-Pacific Region, giving them strategic advantages in position, territory, and resources. Just as the Nazis swiftly conquered most of Europe from the years 1941 to 1942, so did the Japanese; by December 1945 the Japanese were able to conquer Hong Kong (a large slice of China has already been conquered by the Japanese since 1937 in the Sino-Japanese War), and by 1942 Japan was able to conquer Burma, the Dutch East Indies, New Guinea, the Solomon Islands, the Philippines, Malaya, Saipan, and other islands in the Central Pacific.While the Japanese were able to conquer a large part of the Asia-Pacific Region, it came at a large cost, especially in terms of manpower and war material such as carriers, warships, and planes, and this proved to cause difficulties for the Japanese to defend their large conquests. In this case, the offensive plan of the Japanese was to launch further attacks on the south and central Pacific, with the aim of destroying the rest of the remaining aircraft carriers of the United States.
With the Battle of Midway lost for the Japanese, they focused on consolidating their holdings on their territorial gains in the Pacific, and aimed to swiftly conquer the Midway Islands and New Guinea. However, earlier attempts art conquering these territories failed, making them loose a strategic foothold in the Pacific region. With this loss, the Japanese were forced to
fight a defensive war, but still lost attempts to fully control strategic territories in order to cut off supplies from the United States. In the end, they were not able to sustain their gains and lost the war.
