Discussions are spreading in Japan about reconsidering the principle of banning the import of nuclear weapons. Due to China's growing military threat and Japan's reliance on the US nuclear umbrella, some within the Japanese government are calling for a review of the three non-nuclear principles. Defense Minister Koizumi caused a stir by arguing that "Japan should also discuss nuclear weapons." Prime Minister Takaichi is taking a cautious stance, but the Japan Renewal Party directly mentioned the need to reconsider the import ban principle in its suggestions for revising the three major security documents. The three non-nuclear principles have been Japan's basic policy since 1967, but they are becoming controversial along with changes in the surrounding environment. If the review gains momentum, there is also a possibility of backlash at home and abroad and a deterioration in relations between Japan and China.
