Yoshihiko Noda, leader of Japan’s main opposition party, the Constitutional Democratic Party of Japan (CDPJ), has called on the government to uphold the nation’s long-standing non-nuclear principles. This appeal comes amid reports that Prime Minister Sanae Takaichi is considering revising one of the Three Non-Nuclear Principles, specifically the prohibition on introducing nuclear weapons into Japanese territory. Noda, a former prime minister, emphasized Japan’s role in advocating for global nuclear abolition during a press conference in Kumamoto Prefecture. His comments followed Takaichi’s ambiguous stance on whether her defense policies would align with these principles during a recent Lower House Budget Committee hearing. The Three Non-Nuclear Principles, established in 1967 by then-Prime Minister Eisaku Sato, have been a cornerstone of Japan’s security policy. Any potential revision could mark a significant shift in the country’s defense strategy, likely sparking both domestic and international criticism. Noda has vowed to challenge Takaichi on this issue in upcoming Diet sessions.
