Reasons for Austria's involvement in WW11:
Hitler maintained that all German speaking countries should have the same government. After numerous threats to the Austrian government, Hitler ordered his troops into Austria in March 1938. They were then united, partly by force.
Japanese involvement in WW11:
On the 7th December 1941 the Japanese attacked Pearl Harbour. This brought the U.S. into the war with Japan, preceded by Hitler declaring war. The Japanese invaded and over-ran the Philippines, Malaya and the Dutch East Indies. They also penetrated Burma and swept into New Guinea and the surrounding islands. They even bombed Australian ports.
