What's the difference between JR and subway lines?

JR (Japan Railways) runs the major lines including Yamanote. Tokyo Metro and Toei operate the subway lines. Your IC card works on both, but they're separate companies with different route maps.

Do trains really stop running at midnight?

Yes, last trains are between 11:30 PM and 12:30 AM depending on the line. First trains start around 5 AM. Night buses run but are slower and more complex.

How do I know which exit to use at big stations?

Check your destination's address or look it up on Google Maps before arriving. Major stations have 10-20+ exits. Using the wrong exit can add 15 minutes of walking in stations like Shinjuku or Tokyo Station.

Is it really that crowded during rush hour?

Yes, especially on popular routes like Yamanote and Chuo lines. Platform staff will literally push people into cars. Avoid if possible, or position yourself near less popular cars (front and rear).

How to navigate Tokyo's train system like a local

Download Google Maps and Hyperdia apps, buy an IC card (Suica or Pasmo) at any station, and learn the color-coded JR Yamanote Loop line first. Stand on the left side of escalators, let passengers exit before boarding, and avoid rush hours (7-9 AM and 5:30-7:30 PM) when possible.

Get an IC card on arrival. Buy a Suica or Pasmo card at any ticket machine in Narita, Haneda, or your first station. Load it with ¥2,000-3,000 to start. These cards work on all trains, subways, buses, and many convenience stores.
Download essential apps. Install Google Maps (works offline and shows real-time delays) and Hyperdia (the most accurate route planner). Both have English interfaces and work better than station maps for complex routes.
Master the Yamanote Line first. This green loop line connects all major districts. Learn its 29 stations clockwise and counterclockwise. When lost, find your way back to any Yamanote station and navigate from there.
Read the platform signs. Look for your destination name in English under the Japanese characters. Platform signs show the next 3-4 stations and which side doors will open. Stand clear of yellow safety lines.
Follow boarding etiquette. Queue in designated areas marked on the platform. Let all passengers exit completely before boarding. Move to the center of the car. Turn off phone sounds and avoid phone calls.
Navigate transfers efficiently. Follow colored signs matching your destination line. Major transfer stations like Shinjuku have 15+ exits - check which exit number you need before arriving. Save 5-10 minutes by using the correct car position.
Plan around rush hours. Avoid 7-9 AM and 5:30-7:30 PM unless necessary. If you must travel during rush hour, board from the rear cars which are typically less crowded. Consider taking express trains that skip local stops.
