TOKYO, Dec. 27 (Xinhua) -- Former Japanese Prime Minister Shigeru Ishiba has again criticized recent remarks by a senior government official suggesting that Japan should possess nuclear weapons.

Speaking on a program aired Friday night by Japan's BS11 television, Ishiba said that as the only country in the world to have suffered atomic bombings, Japan should take a clear stance on preventing nuclear proliferation and should not make statements that undermine that position.

On Dec. 18, an anonymous senior official in charge of security at the Prime Minister's Office told reporters that Japan should possess nuclear weapons. After the remarks were made public, they sparked widespread criticism and controversy within Japan.

Addressing the issue earlier, Ishiba said that if Japan were to acquire nuclear weapons, it would be forced to withdraw from the Treaty on the Non-Proliferation of Nuclear Weapons as well as the International Atomic Energy Agency. He stressed that such a move would render Japan's nuclear energy policy -- which underpins the country's energy system -- untenable, adding that "this would by no means be beneficial for Japan."

According to a report on the online edition of the Japanese magazine Shukan Bunshun on Dec. 24, the official who made the remarks was Oue Sadamasa, a special advisor to Prime Minister Sanae Takaichi, whose portfolio includes nuclear disarmament and non-proliferation. ■
