Following a senior Japanese official's suggestion that Japan consider acquiring nuclear weapons and the government's subsequent reaffirmation of its non-nuclear principles, the U.S. State Department on December 20 praised Japan as a leader in nonproliferation while underscoring America's nuclear deterrent to protect allies like Japan.
The U.S. response came amid heightened debate sparked by the unnamed advisor to Prime Minister Sanae Takaichi, whose personal opinion on nuclear possession was reported on December 19, prompting Japan's Chief Cabinet Secretary to reaffirm the three non-nuclear principles.
In an email to The Japan Times, a State Department spokesperson sidestepped direct comment on the remarks, stating: “Japan is a global leader and a valuable partner to the United States on nuclear nonproliferation and advancing nuclear arms control.” The U.S. reiterated its National Security Strategy commitment: “The United States will maintain the world’s most robust, credible, and modern nuclear deterrent to protect America and our allies, including Japan.”
This stance reflects the nuanced U.S.-Japan alliance dynamics, where Japan remains a key nonproliferation partner despite regional threats from China and North Korea fueling such discussions. Historically, Japan has adhered to its postwar non-nuclear principles and the Nuclear Non-Proliferation Treaty, though geopolitical pressures have revived debates on deterrence options.
