Japan's old arms in demand as export rules eased

Japan's decision breaks with 70 years of pacifism and reflects Tokyo's pivot to active military engagement with allies. The government cleared rules to export arms to 13+ countries, including Australia, South Korea, and the Philippines. This opens new revenue streams for Japan's defence contractors—Mitsubishi Heavy, Kawasaki, and others—while signalling deeper ties with Indo-Pacific partners wary of China and Middle East instability.

The timing is significant. With the US engaged in Iran war and global supply chains fraying, Japan sees opportunity to position itself as a reliable military supplier. Domestic defence spending is already at 2% of GDP, the highest since WWII. Allowing arms exports amplifies this industrial base without further burdening the budget. China and Russia will view this as provocation; Beijing may retaliate in trade or cyber domains.

Public opinion in Japan remains pacifist, making the shift controversial. Ruling coalition must carefully manage narrative—framing this as alliance-building rather than militarism. If successful, Japanese defence firms will gain market share globally, and Tokyo will deepen security integration with the US and its allies. The risk is escalation spirals and an arms race dynamic in Asia.
