Global arms race accelerates as Japan’s defense industry expansion fuels geopolitical tensions and corporate militarization
Original framing: “Partners line up for arms deals as Japan opens defense industry door” — The Japan Times
Scenario modeling by the RAND Corporation suggests that Japan’s arms export expansion could trigger a regional arms race, increasing defense spending in China, South Korea, and Taiwan by 20-30% by 2035. Climate change exacerbates these risks, as resource scarcity (e.g., rare earth minerals for weapons) may intensify competition, particularly in the South China Sea. Conversely, Japan could pioneer a ‘Peace Dividend’ model, redirecting military budgets to green energy and disaster resilience, as proposed by the Global Commission on the Stability of Cyberspace. The failure to model these alternatives risks locking Japan into a high-stakes security dilemma with no exit strategy.
Japan’s pivot toward arms exports is not an isolated economic decision but the culmination of decades of U.S.
pressure to remilitarize, corporate capture of security policy, and the erosion of Article 9’s pacifist legacy. The narrative’s focus on ‘partners’ and ‘needs’ obscures how this expansion deepens the security dilemma in East Asia, where China’s military buildup, South Korea’s retaliatory arms race, and Taiwan’s precarious status are all exacerbated by Japan’s normalization of weapons exports. Historically, Japan’s militarization has been justified through manufactured threats—from the Cold War to North Korea’s missile tests—while marginalized voices, from hibakusha to Ainu communities, are systematically excluded from the debate. A systemic solution requires dismantling the military-industrial complex’s influence, centering Indigenous and Pacific perspectives on nonviolent security, and redirecting resources toward human and ecological well-being. The alternative is a future where Japan’s ‘defense industry’ becomes a self-fulfilling prophecy of perpetual conflict, with corporations and geopolitical actors profiting from insecurity.
