FOCUS: Japan May Revise SDF Rank Names to Boost Morale

Tokyo, April 3 (Jiji Press)–The administration of Japanese Prime Minister Sanae Takaichi is looking at revising the unique rank titles used by the Self-Defense Forces in fiscal 2026. Under the proposal, the current titles would be replaced by more widely recognized Japanese translations of military ranks used overseas, such as “taisa” and “chusa” for colonel and lieutenant colonel, in an effort to improve public understanding and boost the morale of SDF personnel. Some officials in the Defense Ministry and the SDF say the changes would make the rank hierarchy easier for the public to understand. On the other hand, others have expressed concern that adopting such titles could be seen as a return to terminology associated with Japan’s former Imperial military. Morale and Pride The SDF will mark the 72nd anniversary of its establishment in July. Japan’s postwar Constitution, which came into force in 1947, renounces war and prohibits the maintenance of armed forces under Article 9. Against the backdrop of the Korean War, however, the National Police Reserve was created in 1950, and reorganized into the SDF in 1954. Under the Constitution, the SDF is permitted to maintain only the minimum level of force necessary for self-defense. Aiming to break with the legacy of the Imperial Japanese military before and during World War II, postwar Japan adopted numerical rank designations instead of the traditional titles used by the former military. Under the SDF law, the highest rank is “sho,” equivalent to general or admiral, followed by “shoho,” equivalent to major general or rear admiral. Below them are the field-grade officer ranks–“issa,” “nisa” and “sansa”–and the company-grade officer ranks–“ichii,” “nii” and “sani.” In Japanese, these officer rank names are based on the numbers one through three. On the issue of SDF ranks, uniforms and occupational classifications, the coalition agreement between the ruling Liberal Democratic Party and its partner, the Japan Innovation Party, explicitly states that “international standardization” will be implemented during fiscal 2026, which started this month. At a news conference last November, Chief Cabinet Secretary Minoru Kihara said that Japan faces a security environment more severe and complex than at any time since the end of World War II. He emphasized the significance of the standardization effort, saying that it would “help create an environment in which SDF personnel, who form the core of Japan’s defense capability, can carry out their duties with high morale and pride.” English Translations In terms of equivalence with ranks used by other countries’ armed forces, issa corresponds to colonel, nisa to lieutenant colonel and sansa to major, in the Ground and Air SDF. In the Maritime SDF, the equivalent English titles are captain, commander and lieutenant commander. These English translations are broadly consistent with rank designations used in other countries. SDF officials say that “no particular problems have arisen in daily communication.” Still, one Defense Ministry official suggests there are concerns that rank names based on numbers make it difficult for the public to tell which rank is higher. Adopting titles such as taisa and chusa is expected to make the hierarchy more intuitive and help address this issue. In Japanese, “tai” means great or large, while “chu” means middle. Prewar Military Style Under the proposal, the three lowest enlisted ranks could be given prewar-style titles. In the GSDF, for example, “isshi” and “nishi”–equivalent to private first class and private–might become “ittohei” and “nitohei.” Nevertheless, some Defense Ministry officials have expressed concern that such changes “risk evoking images of the former military,” suggesting that the government may need to proceed cautiously and remain flexible in its approach. It also remains unclear how much changing rank titles would actually improve morale among SDF personnel. One official said, “What would truly affect morale is explicit recognition of the SDF in the Constitution and better treatment for its personnel.” Any change to rank titles would require revisions to legislation such as the SDF law and remuneration law. It would also likely necessitate changes to salary structures, personnel management systems and related equipment, resulting in additional costs and administrative burdens.
