On August 6, 2026, Japan commemorated the 81st anniversary of the atomic bombing of Hiroshima, where nearly 80,000 people were killed in the initial blast during the final days of World War II.

Masako Wada, assistant secretary general of Nihon Hidankyo—the Japan Confederation of A- and H-Bomb Sufferers' Organizations—highlighted Japan's adoption of a pacifist constitution as a reflection on the war. Wada, a Nagasaki bombing survivor, said Japan "earned the trust of the international community as a country that promised never to wage a war again."

However, recent years have seen Japan increase defense spending, ease restrictions on weapons exports, and expand the role of its military, citing growing threats from China, North Korea, and Russia. Masashi Ieshima, 84, a Hiroshima bombing survivor and chairman of Toyukai (Nihon Hidankyo's Tokyo affiliate), criticized this shift, saying, "Japan's recent military buildup is no different from recreating the arms race that led the country toward World War II." He added, "It makes my blood boil to see Japan justify its military buildup and the easing of arms export restrictions over the possibility of a Taiwan conflict."

Japan's Defense Minister Shinjiro Koizumi, speaking on August 4, 2026, stressed the need to strengthen the military with a "sense of urgency and crisis," referencing a government assessment of increasing risks from China, North Korea, and Russia.

In November 2025, Takaichi stated that a Chinese military attack on Taiwan could be a "survival-threatening situation" for Japan, potentially allowing Tokyo to exercise its legal right to collective self-defense.

Despite these developments, Koichi Nakano, a political science professor at Sophia University in Tokyo, noted that the argument for military strengthening based on potential Chinese invasions of Japan or Taiwan is "not convincing" to the Japanese public.

Survivors and activists warn that Japan's current administration is eroding the trust built on its pacifist promises, raising concerns about the country's future direction in regional security.
