Japan's military faces personnel challenges amid declining birth rate and public opposition to foreign recruitment
Quick Look
- A report by senior former defence officials released by the Sasakawa Peace Foundation on September 2 proposed allowing non-Japanese nationals to join Japan's Self-Defense Forces to address personnel shortfalls caused by declining birth rates and an ageing population.
- The government rejected the idea, citing public opposition to immigration and instead focusing on improving conditions for current personnel, supporting veterans, and expanding technology use like AI.
- Employers across Japan struggle to find workers, and analysts note the military lacks appeal for young people, while other countries like Britain recruit Commonwealth citizens.

Why It Matters
Japan's Self-Defense Forces are experiencing personnel shortfalls due to a declining birth rate and ageing population, making recruitment and retention difficult.
The proposal formed part of a report written by a panel of senior former defence bureaucrats and military chiefs, released by the Sasakawa Peace Foundation on September 2.
He acknowledged that “securing human resources is a major challenge in the context of the declining birth rate and ageing population”, but said the government was instead drawing up plans to address personnel shortfalls by improving conditions and facilities for serving members and their families, offering more support after they had left the armed services and expanding the use of technology such as AI.
Employers across Japan are struggling to find workers and analysts say the military holds little appeal for many young people.
While other countries allow non-nationals to serve – Britain, for example, recruits Commonwealth citizens – Japan has shown far greater reluctance to follow suit, a stance that coincides with hardening public opposition to immigration more broadly.
“There are just too many reasons, from the military, the government and the public, why this suggestion is not going to work,” a government adviser on national security told This Week in Asia.
“All arms of the SDF are understaffed at the moment and they are having problems retaining trained people. But this [proposal] has alarmed people.”
