Can I use a credit card directly on the turnstiles?

No. You must use a Suica/Pasmo card (digital or physical) or buy a paper ticket.

How do I know which train to catch?

The signs on the platform show the destination of the next train. If you are unsure, show the station staff the name of your destination in Japanese; they will point you to the correct track.

How to Navigate Tokyo's Train System for Business Meetings

Use a digital Suica or Pasmo card on your smartphone to tap through turnstiles instantly. Download the Japan Transit by Jorudan app to track exact platform numbers and train cars for the shortest walking distance to your specific exit.

Set up your digital transit card. Open your Apple Wallet or Google Pay and add a Suica or Pasmo card. You don't need a physical card; just tap your phone at the reader on the turnstile. This prevents waiting in line to buy tickets.
Use Jorudan for platform precision. Enter your destination station. Look for the 'Platform/Car' feature in the app. It will tell you exactly which train car is closest to the stairs or elevator for your specific exit, saving you minutes of walking through crowded stations.
Exit via the right gate. Look for the exit letter/number on station maps (e.g., 'Exit A4'). Tokyo stations are massive; following the wrong exit sign can add 15 minutes of walking time to your meeting.
Master the train etiquette. Set your phone to silent mode immediately upon entering the train. Do not take phone calls. Stand in the designated lines on the platform and let passengers exit before you board.
