Japan is implementing its largest defense build-up since World War II, planning to allocate 2 percent of its gross domestic product to defense amid growing regional security challenges, according to a Japanese defense document cited by Reuters. Wrenn Yennie Lindgren, head of the Asia Research Center at NUPI and senior researcher at the Center for Geopolitics, describes the shift as a historic acceleration in defense planning driven by a changing geopolitical landscape in Asia.
Historic Defense Shift and Economic Strategy
The Japanese government argues that increased defense investments and weapon production will strengthen national safety while serving as an engine for economic growth, according to Reuters reporting. A defense document released by the government encourages technological investment, support for startups, and the integration of commercial components into weapons manufacturing. “Investments in defense benefit the entire economy and people’s everyday lives,” the document states, as reported by Reuters. Historian Odd Arne Westad notes in his latest book that Japan’s defense budget could reach the world’s third-largest by 2027, trailing only the United States and China.
Did you know? Japan’s defense spending trajectory aims for 2 percent of its GDP, a threshold traditionally associated with NATO members and a major departure from the nation’s historic post-war spending caps.
Regional Security Challenges and China
The Japanese defense document identifies China, Russia, and North Korea as primary security concerns, singling out China as the nation’s foremost strategic challenge. “China’s military activities and other actions cause grave concern to Japan and the international community, and constitute Japan’s greatest strategic challenge,” the document notes. Chinese authorities have rejected the report, accusing Japan of spreading false narratives. Lindgren emphasizes to Nettavisen that the policy shift stems from a combination of regional developments rather than a single threat, pointing to North Korea’s missile programs, the war in Ukraine, and broader geopolitical shifts.
Expanding International Alliances
To counter these emerging pressures, Japan is actively pursuing tighter defense cooperation with global partners, particularly in Europe, according to Lindgren. This outreach includes participation in the Global Combat Air Programme (GCAP) alongside international partners, as well as deeper institutional collaboration with NATO and the European Union. Norway has also strengthened military ties with Tokyo, establishing a strategic partnership in 2023 and signing a defense materiel and technology agreement the following year.
Domestic Politics and Taiwan Strains
Bilateral relations between Tokyo and Beijing have deteriorated to their lowest point in years, exacerbated by remarks from Sanae Takaichi in November. Takaichi stated that Japanese forces could intervene if a Chinese attack on Taiwan threatened Japan’s survival. Chinese officials condemned the remark as gross interference and demanded a retraction. Domestically, Sanae Takaichi—who models her leadership style on Margaret Thatcher and aims to be viewed as Japan’s “Iron Lady,” according to AFP/NTB—faces the task of convincing a public already anxious about the domestic economy that heavy military expenditures are necessary for long-term stability.
