Do I need a Japan Rail Pass for the subway?

No. The JR Pass only covers JR lines (like the Yamanote line). It does not cover Tokyo Metro or Toei Subway lines, which require a separate fare.

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

The gate will stay closed and beep. Use the 'Fare Adjustment' machines located near the exit gates to pay the difference before leaving.

Are the subways 24 hours?

No. Trains typically stop running between 12:30 AM and 5:00 AM. Plan to take a taxi or stay in your district if you are out late.

Navigating the Tokyo Subway System

Tokyo's subway is a network of two main operators, Tokyo Metro and Toei Subway, best navigated using a digital IC card like Suica or Pasmo on your phone. Tap your phone at the yellow gate sensors upon entry and exit to automatically calculate and deduct your fare.

Get an IC card. Add a Suica or Pasmo card to your Apple Wallet or Google Pay. You don't need a physical card; tap your phone's NFC area at the ticket gates.
Use Google Maps for routing. Enter your destination in Google Maps. It will tell you the exact line (e.g., Marunouchi Line), the platform number, and the train's final destination station, which is how signs are displayed.
Follow the color-coded signs. Inside the station, look for signs matching the color of your subway line. If you are taking the Ginza line (orange), follow the orange circles with the 'G' letter.
Mind the platform direction. Trains are identified by the 'last station' on the line. Check your Google Maps route to see if you need to board the train heading towards 'Shinjuku' or 'Ikebukuro' and look for those names on the platform boards.
