After the end of World War II in Asia following the surrender of Japan, the Imperial Japanese Army and Imperial Japanese Navy were dissolved by the Supreme Commander for the Allied Powers during the occupation of Japan. The symbols below represent the ranks of the Japan Self-Defense Forces, the Japan Ground Self-Defense Force, the Japan Air Self-Defense Force, and the Japan Maritime Self-Defense Force which have, since 1952, replaced the imperial military. The 1938–1945 Japanese military and naval ranks were phased out after World War II. The self-defense force breaks away from the Sino-centric tradition of non-branch-specified ranks, each SDF rank with respect to each service carries a distinct Japanese title, although equivalent titles in different branches are still similar, differing only in the use of the morphemes riku (ground) for the army ranks, kai (sea) for the naval ranks, and kuu (air) for the aviation ranks.
