On Saturday, December 20, 2025, Russian Deputy Foreign Minister Andrey Rudenko told the TASS news agency that Moscow is "unequivocally negative" about discussions in Japan to amend constitutional provisions tied to its post-war non-nuclear principles.
Japan’s three non-nuclear principles—never to produce, possess or allow nuclear weapons on its territory—have shaped its defense posture since the 1960s. But earlier this week, an official within the prime minister’s office publicly called for Japan to acquire nuclear weapons, arguing that the move is necessary amid shifting regional security dynamics.
Rudenko warned that any steps toward militarization in Japan would only heighten tensions in Northeast Asia. He added that such moves would likely provoke countermeasures from other nations that feel threatened.
The remarks underscore the delicate balance in Northeast Asian security, where alliances and historical sensitivities influence defense debates. With rising concerns over missile threats and changing diplomatic ties, Japan faces mounting pressure to reconsider its non-nuclear stance—despite public opinion largely favoring the status quo.
As Tokyo and Moscow exchange these warnings, the global community watches closely. Any decision by Japan to pivot toward nuclear armament could have far-reaching implications for arms control, regional alliances, and the broader dynamics between major powers in Asia.
