Japan's 3.5% GDP Defense Spending Proposal: Security and Fiscal Tradeoffs

Japan is weighing a leap from its informal 1% defense-spending norm to as much as 3.5% of GDP (~¥24 trillion, more than double current outlays), driven by Chinese/North Korean threats and U.S. burden-sharing pressure, but the target remains an internal deliberation that Defense Ministry officials publicly deny—and its mere discussion has already spiked JGB yields. The core tensions are unresolved: economists split over whether the sum would crowd out eldercare and social spending or represent necessary deterrence insurance, GDP-ratio comparisons to NATO/South Korea are contested as poor proxies for actual capability, and expanded land-acquisition powers under LURA raise sharp property-rights and local-autonomy objections, particularly from Okinawan communities already bearing disproportionate base burdens.
