A controversial proposal from Japan’s central government to revise the rank nomenclature of the nation’s Self-Defense Forces (SDF) has triggered widespread doubt and criticism across the country, after local media confirmed the administration’s plan to submit amending legislation to the national Diet before the end of 2026.
Among the most contentious changes proposed is the rebranding of the rank currently called “issa”, which translates directly to “first field officer”, to “taisa” — a term that was widely used for officer ranks in the defunct Imperial Japanese Army, the military force that led Japan’s aggressive expansion across Asia in the years leading up to and during World War II. The revival of this pre-1945 military terminology has put the government’s motivations under intense scrutiny.
Japan’s SDF has operated with a unique set of rank titles since the force was formally established in 1954, a deliberate structural choice designed to align with the constraints of Japan’s post-war pacifist constitution. The SDF has long been positioned as a defensive force distinct from conventional national militaries, and this upcoming reform marks the first time the country has revised its military rank naming system since the SDF’s founding. According to a report from Japan’s leading daily newspaper *Yomiuri Shimbun*, the change represents a major policy departure from the framework that has stood for more than 70 years.
Concerns over the reform have spread rapidly across Japanese social media, with many users questioning the government’s reasoning. One user asked publicly, “Titles like ‘taisa’ belonged to the old Imperial Japanese Army. Why are we bringing them back now?” Another commentator pushed back against the government’s official justifications, which frame the changes as a way to build a greater sense of honor and pride among SDF personnel and bring Japanese ranks into alignment with international naming standards. “Can’t our current ranks already instill honor and pride?” the user wrote, adding that the move is a clear reflection of the right-leaning policy orientation of the current Takaichi administration.
Veteran Japanese military journalist Kazutaka Kimura has gone as far as labeling the renaming initiative a “stupid policy” in public commentary. Ryo Tsunoda, a senior researcher at Japan’s Ritsumeikan University, noted that for decades, the Ground Self-Defense Force has intentionally distanced itself from the legacy of the Imperial Japanese Army as part of Japan’s broader reflection on its wartime responsibilities. Tsunoda added that the government’s claim that the public will accept the renaming as nothing more than a symbolic measure to boost respect for the SDF remains highly unproven, with broad public skepticism still lingering across Japanese society.
