Flight arrival times matter more than distance. Haneda is closer (30 min vs 60 min to central Tokyo) but Narita often has better international flight schedules and cheaper fares.

Haneda advantages: Monorail to Hamamatsucho connects to JR Yamanote Line easily. Last trains run until midnight. Domestic terminal has better food options.

Narita advantages: Skyliner to Ueno is comfortable and has reserved seats. More international carriers. Immigration lines move faster. Better duty-free shopping.

If you're arriving after 11pm, Haneda is your only option for trains. Otherwise, compare total door-to-door time including your final destination.
