**Japan Just Ended Its 80-Year Weapons Ban | The Defense Industry Wakes Up**

---

On April 21, 2026, Japan's cabinet voted to end the arms export ban it has lived with since 1947. Fighter jets, missiles, warships — all now eligible for overseas sale. This is the most consequential shift in Japan's defense posture since the country wrote pacifism into its constitution. But it's also a business story that almost nobody is covering.

Japan's defense industry spent eighty years in a strange trap: world-class manufacturing capabilities, but only one customer — the Japan Self-Defense Force. The domestic market was too small to justify serious investment. Dozens of subcontractors quietly exited. Major contractors like Mitsubishi Heavy Industries and Kawasaki Heavy kept the lights on but couldn't scale. The sector that a country like the United States uses to project global influence became, in Japan, a protected but quietly declining obligation.

Now the rules have changed completely. Japan can sell to seventeen allied nations. The National Security Council must approve each transaction. And Mitsubishi Heavy Industries — a $34 billion company that also builds liquefied natural gas carriers, power systems, and turbines — is now staring at a global market it was legally forbidden from entering.
