Ranks and insignia of the Japan Self-Defense Forces

The Ranks and insignia of the Japan Self-Defense Forces are the military insignia used by the Japan Self-Defense Forces.

History
Following the end of World War II in Asia, after the surrender of Japan, the Imperial Japanese Army and Navy were dissolved by the Supreme Commander for the Allied Powers in 1945, during the Allied occupation that lasted until 1952. The 1947 constitution stipulated that armed forces with war potential will not be maintained.

The symbols below represent the ranks of the Japan Self-Defence Forces: the Japan Ground Self-Defence Force, the Japan Air Self-Defence Force, and the Japan Maritime Self-Defence Force, which replaced the imperial military in 1954.

The 1871–1945 Japanese military and naval ranks were phased out after World War II. The Self-Defence Force breaks away from the Sino-centric tradition of non-branch-specified ranks; each JSDF 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 (maritime) for the naval ranks, and kū (air) for the aviation ranks.

The pentagramic stars on the insignia represent cherry blossoms. Because Japanese soldiers take an oath to die to protect the lives and wealth of Japanese citizens, they have been compared to delicate cherry blossoms that break easily.
