Japan's leader has said he will visit Pearl Harbour with US president Barack Obama at the end of this month.
No serving Japanese prime minister has ever visited the US naval base in Hawaii that was attacked by Japan in 1941, propelling the United States into the Second World War.
Prime Minister Shinzo Abe said he will visit Hawaii in late December and hold a final summit meeting there with Mr Obama before the American leader leaves office.
Earlier this year, Mr Obama became the first sitting US president to visit the memorial to victims of the US atomic bombing of Hiroshima at the end of the war.
