What’s in a name? Japan moves to revive World War II-era military ranks

The plan, backed by the Liberal Democratic Party (LDP) and its junior partner Nippon Ishin (Japan Innovation Party), would restore imperial-era rank titles for members of the Self-Defense Forces (SDF). 

They said the change is meant to adjust to "international standards.” 

Since the SDF was established in 1954, Japan has deliberately used rank names that differ from those of its pre-1945 military. The distinction was designed to signal a clean break from the wartime past and reinforce the force’s defensive role under Japan’s pacifist constitution.

Under the current system, Japanese rank names do not match the old imperial terminology, even though their English translations already correspond to standard military ranks used overseas. 

For example, the SDF rank equivalent to a colonel is “issa,” or “first field officer,” which replaced the imperial-era term “taisa.” While the Japanese titles were changed after the war, their English equivalents have long matched international military ranks.

Any change to rank names would require amendments to the Self-Defense Forces Law and approval by parliament.

Pusback

Inside the Defence Ministry and the SDF, however, the proposal has been met with scepticism.

Some officials noted that reviving terminology associated with the imperial military risks complicating recruitment efforts and unsettling public perceptions, especially among younger generations.

Particular resistance has focused on lower enlisted ranks such as ittohei (private first class) and nitohei (private). Critics argue that these terms carry outdated or negative connotations tied to Japan’s wartime army.

What’s more unsettling is that the debate has also drawn attention from Japan’s neighbours. 

China and North Korea have criticised the proposal as further evidence of Tokyo drifting away from its postwar pacifist stance.
