Japan is on edge.

The unexpected victory of billionaire businessman Donald Trump in the US election has caused great anxiety in the country.

Prime Minister Shinzo Abe will fly to New York on Thursday to meet the president-elect - his predecessors were never so anxious to talk to the winner of a US presidential election before. Abe had actually scheduled a visit to Washington in February to see Hillary Clinton, whom he thought would be the next incumbent of the White House.
