Japan vows never to possess nuclear weapons, rebuffing official’s idea
The government’s response came after a senior security official suggested that Tokyo needed nuclear arms to deter potential aggressors

At a regular press briefing in Tokyo, Chief Cabinet Secretary Minoru Kihara said Japan’s nuclear policy had not changed, but declined to comment on the remarks or to say whether the person would remain in the post amid calls from opposition leaders for the official to be removed.
There is a growing political and public willingness in Japan to loosen its three non-nuclear principles not to possess, develop, or allow nuclear weapons, an investigation published in August found.

Japan hosts the largest overseas concentration of US military forces and has maintained a security alliance with Washington for decades.
