What's the difference between JR and Tokyo Metro?

JR is the main rail company (green Yamanote line, longer distances). Tokyo Metro runs the subway (shorter distances, underground). Your IC card works on both, but they're separate companies with different route networks.

Can I use my phone to pay instead of an IC card?

Only if you have a Japanese phone or FeliCa-enabled device. Foreign phones can't use Mobile Suica. Stick with the physical IC card.

What if I take the wrong train?

Don't panic. Get off at the next station and cross to the opposite platform. Tokyo stations have clear signage for direction changes, and station staff speak basic English.

How early should I arrive for rush hour trains?

Add 15-20 minutes to your normal travel time during rush hours. Trains run every 2-3 minutes, but boarding takes much longer when platforms are crowded.

How to navigate Tokyo's train system like a local

Download Google Maps and Hyperdia apps, get a rechargeable IC card (Suica or Pasmo), and learn the color-coded line system. Most importantly, follow the flow of people during rush hours and always stand on the left side of escalators.

Get an IC card on arrival. Buy a Suica or Pasmo card from any station machine for ¥500 deposit plus your initial charge (start with ¥2000). These work on all trains, subways, buses, and even convenience stores. Skip paper tickets entirely.
Download essential apps. Install Google Maps (works offline and shows real-time delays) and Hyperdia (more detailed route planning). Both apps work in English and show platform numbers and transfer walking times.
Learn the color system. Each line has a color and letter code (JR Yamanote is green/JY, Tokyo Metro Ginza is orange/G). Stations display these prominently. Follow the colors, not just station names.
Master rush hour etiquette. 7-9 AM and 5:30-7:30 PM are brutal. Stand to the left on escalators, let people exit before boarding, remove your backpack in crowded cars, and don't eat or talk loudly. Follow the crowd flow.
Use transfer strategies. Major hubs like Shinjuku and Shibuya have 10+ exits. Check your app for the exit number before arriving. Walk in the middle of the platform to avoid crowding near escalators.
Handle the last train. Last trains run around midnight. Miss it and you're taking a ¥3000+ taxi or waiting until 5 AM. Check Hyperdia for 'last train' times when planning late nights.
