What the aircraft actually flies over
From Tokyo the path crosses Japan, then 614 km of open water, then South Korea.
The furthest the great circle gets from the equator is 37.5°N, 100% of the way along.
Holding a single compass bearing the whole way would cover almost exactly the same ground, so on this route the flat map and the globe agree.
Leaving Tokyo the aircraft points west (284°); it arrives into Seoul heading west (276°). That is 8° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
