Japan’s defense export surge amid US distrust: systemic shift in global arms markets and geopolitical realignment

Japan’s remilitarisation threatens indigenous Ainu land rights and cultural heritage, as military bases expand into ancestral territories in Hokkaido. The Ainu, who were historically displaced by imperial expansion, now face renewed dispossession under the guise of national security. Indigenous Pacific communities, such as those in Okinawa and Guam, also bear the brunt of US-Japan military integration, with sacred sites and fishing grounds militarised. These communities’ resistance is framed as ‘anti-state’ rather than as legitimate defense of sovereignty.

Japan’s current arms expansion mirrors post-WWII rearmament under US pressure, when Article 9 was reinterpreted to allow ‘self-defense’ forces. The 1951 US-Japan Security Treaty laid the groundwork for Japan’s dependent militarism, which is now being repurposed for export-led growth. Historical parallels with Germany’s post-Cold War arms industry show how economic incentives can override pacifist norms. The US’s current push for allies to ‘share the burden’ echoes Cold War-era demands for military spending.

In Europe, Germany’s arms exports are similarly framed as ‘defensive’ despite fuelling conflicts in the Middle East, revealing a global pattern of militarised economic diplomacy. In India, the ‘Make in India’ defense initiative has led to collaborations with Japan, but these are often extractive, benefiting foreign firms over local communities. Pacific Island nations, such as Fiji and Vanuatu, view Japan’s arms push as a threat to regional stability, contrasting with Southeast Asian states that see it as a hedge against China. These divergent views highlight how ‘security’ is culturally and geopolitically constructed.

Economic studies show that defense exports rarely stimulate sustainable growth and often lead to dependency on volatile security markets. Research on arms races demonstrates that increased military spending correlates with higher conflict risk, contradicting the ‘stability through strength’ narrative. Japan’s shift aligns with global trends where arms exports are used as a tool of coercive diplomacy, as seen in Saudi Arabia’s purchases from the US and UK. The scientific consensus warns that militarised economic policies undermine long-term peace and development.

Japanese artists and writers, such as Kenzaburo Oe, have long critiqued the spiritual emptiness of militarism, linking it to the loss of communal values. Okinawan musicians and poets, such as Shoukichi Kina, use art to resist US military bases, framing them as spiritual desecration. In contrast, nationalist narratives in Japan depict remilitarisation as a return to ‘normalcy,’ erasing the trauma of WWII. These artistic responses reveal the cultural fractures underlying Japan’s strategic shift.

If Japan’s arms exports grow, it could trigger a regional arms race, particularly with China and South Korea, destabilising East Asia. A scenario where Japan becomes a top arms exporter may lead to ethical dilemmas, as seen with Israel’s arms industry, where human rights abuses become collateral damage. Future modelling suggests that economic reliance on arms exports could make Japan vulnerable to US pressure, repeating the cycle of dependent militarism. Long-term peace may require Japan to reject arms-led growth and invest in demilitarised diplomacy.

Okinawan women’s groups, such as the Okinawa Women Act Against Military Violence, have led protests against US military bases for decades, yet their voices are excluded from mainstream narratives. Japanese pacifist organisations, like the Japan Council Against Atomic and Hydrogen Bombs, warn that remilitarisation undermines Article 9’s legacy. Indigenous Ainu activists, such as those in the Ainu Association of Hokkaido, argue that military expansion threatens their cultural survival. These voices are systematically marginalised in favor of elite security narratives.
