Hi, Welcome to Living and Working in Korea.
I'm Ryan, M, Korean CPA.
Seoul's subway system is legitimately one of the best in the world—clean, efficient, and filled with the kind of people who actually respect personal space.
Seoul Metro Etiquette: Complete Guide to Subway Rules & Customs
But there's a catch: unwritten rules everywhere.
You'll breeze through perfectly fine, or you'll catch enough side-eye to power a small city. Here's what you actually need to know.
Let Them Out First (Seriously)
The golden rule, the foundation, the thing locals will judge you for if you mess it up.
When the doors open, wait. Let everyone exit before you even think about stepping in. Not just a polite gesture—people have places to be, and crushing yourself against someone trying to leave looks desperate.
Pro move: Stand to the side of the doors, ideally off to the left or right. Don't camp directly in front.
When the doors close behind the last person getting off, then you board, preferably in an orderly fashion (more on that below).
Those Colored Seats Aren't for You (Probably)
About 30% of all subway seats are reserved for priority riders: the elderly, pregnant women, people with disabilities, and anyone traveling with young kids.
Easy to spot—they're bright colors (pink, orange, red) and marked with signs that have pictures of exactly who should sit there.
Here's the thing: even if the subway is packed and these seats are empty, don't sit in them unless you genuinely need one. This is a trust-based system, not enforced by law, which somehow makes it more serious. Koreans will notice. They will think less of you. They might stare. Is it worth it to avoid standing for two stops? No.
The pink seats? Those are specifically for pregnant women, even ones who don't look obviously pregnant.
If you're expecting, take a seat without guilt. If you're not, keep walking.
The Sacred Quiet
Subways are silent places. This isn't a suggestion. Phone calls are basically public enemy number one. If you must take one, whisper and keep it under five seconds. People text instead—that's the move.
Talking loudly with friends? Also a no. Listen to music and videos only through headphones. If you're blasting something speaker-style, you've made a choice that will haunt you. The stares are real.
Late night? Still quiet. Even drunk people somehow manage to keep it down. It's like subway white-glove service for peace and quiet.
Backpack Battles
Big backpack? Take it off during crowded hours (rush hour is 7:30–9:30 AM and 6–8 PM). Wear it on your front if space is tight, or tuck it between your legs if you're sitting. Your backpack poking someone in the face is not the cultural exchange moment you want.
Stand, Don't Sprawl
If you're sitting, keep your feet planted and your legs together. Don't spread your legs wide—that person next to you will silently resent you. Crossed legs where your foot dangles into someone's space? Also not cool. The seats are snug. Sit snug.
No Eating or Drinking
The rule seems strict until you remember you're in a metal tube with 200 other people. Eating smells. Drinking spills. Just don't. Coffee is borderline acceptable because it's already in a closed container, but even that's pushing it.
The exception is late-night drunk people eating fried chicken, but that's chaos energy, and you don't want to be that person.
Escalator Geometry
This one's straight: stand on the right, walk on the left. Even if you're tired. Even if you're lazy. There's a flow, and people in a hurry need the left side. This applies everywhere—not just subways.
Bikes Aren't Allowed (During weekdays)
Bringing a bike? They're banned from weekdays to prevent blocking walkways. Outside those times, you can take them on.
No Pets (Unless They're Service Animals)
Dogs, cats, rabbits—they need to stay home. There was literally an incident where someone didn't clean up after their dog. That person is probably still being talked about.
The good news:
get these right, and you'll blend in better than most people ever expect. You'll have mastered a system that billions of people stress about. You'll be the quiet, considerate foreign rider. That's the ultimate flex.
