Trump's Japan visit to honor alliance

The state visit of United States President Donald Trump to Japan began on Sunday morning with a round of golf with Japanese Prime Minister Shinzo Abe, followed by the Summer Grand Sumo Tournament where the US leader presented the President's Cup to the winner.

The centerpiece of the trip will be Trump's time on Monday with newly installed Japanese Emperor Naruhito, who has heralded the start of the new reign. The royal couple will host, as is traditional for state visits, a formal dinner banquet for Trump on Monday.

Trump is the first foreign leader to make a state visit to Japan since the May 1 enthronement of Naruhito.
