Full route notes
Departing Incheon eastward over the Yellow Sea, the aircraft crosses the Korea Strait past Tsushima Island before climbing over the Sea of Japan and descending across Honshu toward the Kanto Plain. Mt Fuji sits roughly to the south of the inbound track, making it a classic right-side landmark on the final descent into Narita.
The Seoul–Tokyo corridor is one of the world's busiest international routes, connecting two of Asia's largest metropolises across the narrow Sea of Japan.
Actual paths can shift by 10-30 km due to airline routing, wind, weather, or air traffic control.
Timing, weather, and airline variation
Morning
Morning flights from Seoul have the sun to the left (north side), keeping the right side shadow-free and clear for Mt Fuji views on descent.
Evening
Evening arrivals into Tokyo can produce stunning sunset light over Mt Fuji to the right; the Pacific coast glows orange on the right side.
Weather
Even on overcast days the Korean Strait and Narita approach provide visual interest; Mt Fuji is only reliably visible on clear days.
Airline routes
Different carriers may file slightly different paths, especially on long-haul routes, but the right side is the statistically stronger pick for the standard route.
