Subway Express: Navigating Tokyo, Seoul, and Taipei Without Wasting a Minute
Published by Sortsyrankbrry Transit Engineering Unit • 2026
Navigating Asia's transit systems can either be a joyful exercise in precision engineering or an overwhelming maze that swallows hours of your 48-hour schedule. Here is how to navigate like a seasoned express commuter.
1. The Car Position Advantage
In Tokyo and Seoul, station platform screen doors list exact train car numbers matching station exits. Apps like Google Maps or Naver Map tell you precisely which car to board (e.g., "Board Car 4-2 for fastest transfer to Line 2"). Riding in the correct car saves 6-10 minutes of walking per transfer.
2. Express vs. Local Train Disambiguation
Always verify train indicators. On lines like the Keikyu Main Line in Tokyo or Line 9 in Seoul, hopping on an Express train instead of a Local train cuts transit times in half. Watch station screen departure indicators closely.
3. Exit Number Mastery
In Seoul and Taipei, subway stations span multiple city blocks with up to 14 exits. Never exit to street level before confirming your target exit number underground. Taking the wrong exit can add a 15-minute detour.
