Japan Approves Export of Lethal Weapons After Revising Defense Equipment Transfer Rules, Igniting Regional Condemnation and Mass Protests

On April 21, 2026, the Japanese government formally approved a revision to its “Three Principles on Transfer of Defense Equipment and Technology” and the accompanying implementation guidelines through a cabinet resolution, opening the door for the export of lethal weapons. Kyodo News described the revision as a major turning point for Japan’s security policy, which had long been anchored to its identity as a “peace nation.” On the same day, Prime Minister Sanae Takaichi sent a ritual offering to the Yasukuni Shrine in her capacity as prime minister. Earlier, on April 8, the Diet had passed the fiscal 2026 budget, under which defense spending surpassed a record 9 trillion yen. On April 19, approximately 36,000 Japanese citizens rallied around the Diet building in Tokyo to protest the constitutional revision and military buildup, marking the second mass anti-revision gathering of over 30,000 since April 8.

On April 27, China declared before the UN Security Council that Japan’s “neo-militarism” has grown into a menace threatening regional peace and stability. North Korea on April 15 branded the Japanese diplomatic bluebook’s opposition to Pyongyang’s nuclear program as a “grave provocation,” while South Korea’s Foreign Ministry expressed deep concern over Tokyo’s military expansion. Days later, Prime Minister Takaichi made remarks citing the wars in Ukraine and the Middle East as lessons to “prepare for a prolonged war.” With 2026 marking the 80th anniversary of the Tokyo Trials, Japan’s accumulating re-militarization measures have stirred widespread international apprehension over its departure from its postwar pacifist path.
