Kazakhstan's leader arrived in Japan with a four-day visit on Sunday.
According to the NHK broadcaster, during his speech in the Japanese parliament, Nazarbayev called for ban of nuclear weapons across the world, adding that he would urge the international community to stop spread of such weapons, as well as nuclear tests.
The media outlet added that the president said that countries of the world should use their political will to increase trust among nuclear-armed countries.
Japan is the only country that has been attacked with the use of nuclear weapons. In 1945, the United States dropped two atomic bombs on Hiroshima and Nagasaki, on August 6 and 9 respectively. The bombing in Hiroshima killed about 150,000 people, and the raid on Nagasaki claimed the lives of some 70,000 people.
