At a Hiroshima memorial ceremony, Japan's prime minister said the country "maintains" its three long-standing non-nuclear principles, reports UPI. But the prime minister "stopped short of promising that the policy would remain unchanged, fueling speculation that her government could review a longstanding ban on allowing nuclear weapons into the country." [Prime Minister Sanae] Takaichi made the remarks Thursday at the Hiroshima Peace Memorial Ceremony marking the 81st anniversary of the U.S. atomic bombing of the city... Unlike previous prime ministers who pledged that Japan would "continue to uphold" the principles, Takaichi described the government's current position without making an explicit commitment about the future [only saying that Japan has "a mission to continue efforts toward realizing a world without nuclear weapon..."] The wording has drawn attention because her government plans to revise Japan's three key national security documents by the end of the year. At a news conference after the ceremony, Takaichi again said the government "maintains the Three Non-Nuclear Principles as a matter of policy." Asked whether the principles would continue to be included in the revised security documents, however, she declined to commit, saying she would refrain from prejudging the outcome. Japan's Three Non-Nuclear Principles state that the country will not possess nuclear weapons, will not produce them and will not permit their introduction into Japanese territory. The principles originated with a 1967 statement by then-Prime Minister Eisaku Sato and have remained a central element of Japan's postwar nuclear policy. Takaichi has previously questioned the third principle — the prohibition on allowing nuclear weapons into Japan. Before becoming prime minister, she argued in a 2024 book that Japan should retain the commitments not to possess or produce nuclear weapons but that an absolute prohibition on their introduction was unrealistic. Her argument was that barring port calls by U.S. vessels carrying nuclear weapons could limit the effectiveness of the U.S. nuclear umbrella protecting Japan... The Japan Innovation Party has also called for a review of the third principle. In security policy recommendations submitted to the government in June, the party called for a "realistic review" of the ban on allowing nuclear weapons into Japan... Under existing government interpretations, Japan could respond flexibly in an extreme national emergency involving a U.S. vessel carrying nuclear weapons. Some within the ruling party therefore question whether formally revising the non-nuclear principles would provide enough practical benefit to justify the political controversy it would create. Critics also warn that changing the policy when Washington has not publicly demanded such a move could give China and North Korea additional grounds to portray Japan as expanding its military role... If Japan were to allow temporary entry by U.S. nuclear weapons or port calls by nuclear-armed vessels, Washington would gain additional operational options for its nuclear forces in Northeast Asia. Such a development could strengthen deterrence against North Korea and China but could also intensify debate over differences between U.S. extended deterrence arrangements with Japan and South Korea. "How the principles are addressed in Japan's revised security documents later this year could determine whether the issue develops into a broader debate over the future of extended nuclear deterrence among Japan, South Korea and the United States..."
