Japan’s government and the ruling Liberal Democratic Party are putting the Self-Defense Forces’ staffing shortage at the center of defense policy. The plan is to improve pay and post-service support and to write the goal into the three national security and defense documents due for revision at the end of 2026.
That is the picture in a Jiji report carried by The Japan Times on 19 October 2026. Officials worry that the shortage, which appears set to worsen as the birth rate falls, could make it harder for Japan to build up its defense capabilities. Detailed figures and measures come from the UA.News syndication of the report.
The Numbers
Defense Ministry data show 217,701 personnel at the end of March against an authorized strength of 247,154, or 88.1 percent. If current trends hold, the ministry projects about 180,000 by fiscal 2035 and about 130,000 by 2045, roughly half of today’s authorized level. A senior Ground Self-Defense Force officer said the shortage “increases the burden on each service member and could weaken the organization.”
The Package
The measures include a revised pay system, expanded support for members after they leave service, and a clearer commitment to personnel conditions in the year-end security documents. Defense Minister Shinjiro Koizumi is pushing for a new government body in fiscal 2027, not yet named, to help former members and their families, including with finding work. Chief Cabinet Secretary Minoru Kihara said the government must improve conditions for those serving now and also create an environment in which former personnel and their families can take pride in their lives.
A new LDP parliamentary group led by former Defense Minister Itsunori Onodera is drafting proposals for the government, including a higher retirement age. Many members now leave in their mid-50s under early-retirement rules meant to keep units young and combat-ready. The ministry also says it needs to use technologies such as uncrewed aerial vehicles more actively, so that it can keep defense capability with fewer people.
Why It Matters
The following is analysis, not part of the reporting.
Japan is the second U.S. ally in Northeast Asia in a single week to say openly that demography now limits force design. Seoul has told its National Assembly it will halve its enlisted air force ranks by the 2040s. Tokyo is now putting a possible fall to 130,000 uniformed personnel into its core strategy documents, at the same time as it carries out its largest defense build-up in decades.
The practical result is that budgets alone will not deliver the capability Japan has funded. Retention, later retirement and post-service security are about making a career attractive to recruits. Uncrewed systems are about making each person count for more. How far the December documents connect personnel policy to force structure, rather than treating it as welfare, will show how seriously Tokyo takes the problem.
