This might have something to do with the fact that the two Hokkaido and Tokyo are on two different islands.
In addition you can fly in Germany from Hamburg to Berlin and Munich. But still most people use the train. For two reasons. Hamburg Berlin is 1.5 hours by train you cannot reach the plane in that time and definitely not fly. Munich req. 6 hours by train so a plane might be faster, but you can jump on a train every hour without planning for a specific hour. You cannot do that with a plane.
