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. They were eventually replaced by the Japan Self-Defense Forces 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.

In 2025, the Liberal Democratic Party–Japan Innovation Party coalition announced plans to rename ranks in the JSDF to more align with their international equivalents. Xinhua News Agency and The Asahi Shimbun highlighted that the new rank names are the same as those that existed in the Imperial Japanese Army, with Xinhua News Agency stating that this shows Japan is choosing to remilitarise.
