Tokyo, Nov 16, 2025
Japanese Prime Minister Sanae Takaichi was considering reviewing the country’s long-standing Three Non-Nuclear Principles, which is certain to draw backlash.
In updating Japan’s National Security Strategy and two related documents, last revised in 2022, Takaichi was considering revising the third principle, which prohibits nuclear weapons from entering Japan’s territory, Xinhua news agency reproted quoting Kyodo News (citing government sources).
If the principle is changed, it will represent a significant shift in the country’s security policy and is certain to draw domestic and international backlash, the report said.
The Three Non-Nuclear Principles, not possessing, not producing and not allowing introduction of nuclear weapons into Japanese territory, were first declared in the Diet, Japan’s parliament, by then Japanese Prime Minister Eisaku Sato in 1967 and viewed as a national credo.
The national security strategy, one of the three documents approved by the Cabinet in 2022, states, “The basic policy of adhering to the Three Non-Nuclear Principles will remain unchanged in the future.”
While Takaichi has no intention of revising Japan’s stance on not possessing or producing nuclear weapons, she believes that not permitting the introduction of nuclear arms could hinder port calls by US nuclear-armed vessels, therefore weakening US nuclear deterrence, the report said.
During a recent Lower House Budget Committee hearing, Takaichi avoided stating whether her defense and security policies would adhere to the Three Non-Nuclear Principles that Japanese administrations have followed for decades.
An editorial published in the Japanese newspaper Asahi Shimbun pointed out that as a country that suffered atomic bombings, Japan has positioned the Three Non-Nuclear Principles as a national policy, which has long received widespread support from the Japanese people.
Takaichi should understand that the policy of adhering to the Three Non-Nuclear Principles can not be rashly changed by hasty judgment of the prime minister, the editorial said.(Agency)
