After 1900 Japan aligned itself with Britain, and Germany and Japan were enemies in World War I. Japan declared war on the German Empire in 1914 and seized key German possessions in China and the Pacific. In the 1930s, both countries adopted aggressive militaristic attitudes toward their respective regions. Hope this helped!!
