Can I use my credit card at the turnstiles?

No. Tokyo turnstiles only accept IC cards (Suica/Pasmo) or magnetic paper tickets. You cannot tap your contactless credit card directly on the train readers.

What happens if I don't have enough money on my IC card?

Don't worry. If your balance is too low when you exit, go to the 'Fare Adjustment' machine near the exit gates, insert your card, and pay the remaining balance in cash.

Navigating Tokyo's Train System Like a Local

Skip paper tickets and buy a Welcome Suica or Pasmo Passport IC card at the airport for seamless tapping at every gate. Use the Japan Transit by Jorudan app to calculate the exact platform number and shortest transfer routes between lines.

Get an IC card immediately. Upon arrival at Haneda or Narita, head to the JR East Travel Service Center to buy a Welcome Suica or Pasmo Passport. These reloadable cards cover all train and subway lines; you just tap your card on the reader when entering and exiting the gate.
Master the digital maps. Download Google Maps or Japan Transit by Jorudan. Always input your destination in English; the app will tell you which car of the train to board to be closest to your transfer stairs, saving you minutes of walking.
Understand the color coding. Tokyo trains are color-coded by operator. JR lines (like the Yamanote loop) are green/silver. Tokyo Metro lines are identified by a letter (e.g., 'G' for Ginza) and a number. Look for the colored signs hanging from the ceiling to navigate between lines.
Mind the platform behavior. Stand behind the yellow lines while waiting. Form two neat lines on either side of the doors, leaving the center clear for passengers exiting the train first. Never stand in the middle of the platform.
