Emperor Akihito on Thursday voiced his deep anticipation for global peace, saying new generations must not forget the sacrifices made during the war.

"Sixty-four years have passed since the war ended, and three out of every four Japanese now were born after the war," the Emperor said at a ceremony in Tokyo to celebrate the 20th anniversary of his coronation.

"It must not be forgotten that today's Japan is built on huge sacrifices, and it is important for this country's future to pass that on to those born after the war," he said.
