At 4:13 p.m. on April 20, Prime Minister Shinzo Abe arrived at Haneda airport in Tokyo, wrapping up a four-day trip to the United States to discuss bilateral trade and North Korea with President Donald Trump.

Abe, however, didn't have a minute to spare. He headed straight to a meeting at a hotel in Minato Ward, arriving in just 35 minutes by car.
