In a year in which nuclear disarmament hopes have been dented by not-so-subtle references by Russia to its own arsenal following its invasion of Ukraine, Prime Minister Fumio Kishida is set to make history as the first Japanese leader to address the United Nations' nuclear nonproliferation treaty review conference, which begins in New York on Monday.

Kishida, who represents a district in Hiroshima, is expected to call for a world without nuclear weapons and for greater transparency among nuclear powers regarding their stockpiles and capabilities. His message will refer to Japan's experience as the only country to have been attacked with an atomic bomb. The leader will also stress that all countries should neither use nuclear weapons nor threaten to use them.

Speaking to reporters in Tokyo on Friday, the prime minister said it was important to link the treaty's ideals with current geopolitical realities.
