Japan's biggest military taboo since World War II has just been shattered. China and North Korea are to blame

Japan is moving its Kaga helicopter destroyer toward F-35B operations in joint drills with U.S. Marines.

The tests, including landings and deck maneuvers, signal a shift toward a light carrier capability.

The Kaga and Izumo conversions reflect Tokyo’s response to growing pressure from China and North Korea.

The move marks Japan’s clearest break from postwar military limits and strengthens its regional airpower reach.
