The Imperial Japanese Navy conducted the majority of Japan's military operations during World War I. Japan entered the war on the side of the Entente, against Germany and Austria-Hungary as a consequence of the 1902 Anglo-Japanese Alliance. Japanese participation in the war was limited. Campaigns or operations included the capture of Tsingtao, the hunt for the German East Asia Squadron, the capture of German colonies in the Pacific, and operations in the Mediterranean. These were noteworthy events, but considered marginal to the outcome of the war.
