Tokyo: Japan will not sign a United Nations treaty to ban nuclear weapons, a top government official insisted on Monday.
The UN said 50 countries have ratified the Treaty on the Prohibition of Nuclear Weapons, known as the TPNW, paving the way for it to come into effect in 90 days.
Japan's Chief Cabinet Secretary Katsunobu Kato said Japan shared the goal of achieving a nuclear-free world but did not think the treaty was the way to go.
"Japan's approach is different from that of the treaty, and there is no change to our position not to sign it," he told reporters.

The UN announcement was hailed by anti-nuclear activists, including survivors of the nuclear bombs dropped over Japan in 1945.
But the treaty has been strongly opposed by the United States and the other major nuclear powers.
With nuclear powers and non-nuclear weapons states sharply divided over the treaty, it was not realistic to pursue the goal, Kato said.
