- Nihon Hidankyo survivors warned Japan's military buildup "is no different from recreating the arms race that led the country toward World War II," with 84-year-old Hiroshima survivor Masashi Ieshima, who was 1.2 miles from the hypocenter at age 3, saying continued buildup could lead to nuclear war.
- Japan commemorated the 81st anniversary of the August 6, 1945 atomic bombing, with the average age of "hibakusha" survivors now reaching almost 87 and the urgency of passing testimony to younger generations intensifying.
- PM Sanae Takaichi's government, in office since October 2025, relaxed arms export restrictions in April 2026 to allow lethal weapons and is considering revising Japan's three non-nuclear principles of not possessing, producing, or permitting the entry of nuclear weapons.
- Defense Minister Shinjiro Koizumi wrote in the latest annual defense white paper that Japan must strengthen its military with "a stronger sense of urgency and crisis than ever before," citing China's military expansion and activities around Taiwan.
- Takaichi said in November 2025 that a Chinese military attack on Taiwan could constitute a "survival-threatening situation" for Japan, potentially allowing Tokyo to exercise its legal right to collective self-defense.
- Sophia University Prof. Koichi Nakano argued the China-threat narrative is "not convincing" to the Japanese public, noting China's military activities remain limited compared with Russia's war in Ukraine and US attacks on Iran.
- Around 27,000 people gathered outside Japan's parliament on July 10 in anti-war protests, with civic organizers telling DW that activism is increasingly led by people in their 20s to 40s and women.
Why it matters: Japan's postwar pacifist constitution anchored its international identity for eight decades, but Takaichi's government — in office only since October 2025 — has already eased restrictions on lethal arms exports, signaled possible revision of the three non-nuclear principles, and framed a Taiwan conflict as a Japanese survival threat, drawing fierce opposition from aging survivors who say the moves destroy the trust Japan earned after 1945.
