Forget taxis (unless you're in a real pinch or have a lot of luggage). The subway is :

• Fast : Seriously fast. Trains arrive every few minutes, and they whisk you across the city in no time, bypassing all the surface traffic.

• Punctual : You could set your watch by the Tokyo subway. Delays are rare, and if they happen, announcements are swift and clear.

• Extensive : With over a dozen lines operated by various companies (primarily Tokyo Metro and Toei), the subway covers virtually every corner of the city you'd want to visit.

• Affordable : Compared to other major global cities, Tokyo's subway fares are quite reasonable, especially if you get a travel card.

• Clean and Safe : Tokyo's trains and stations are impeccably clean, and the system is incredibly safe, even late at night.

Ready to dive in? Here are a few things that will make your subway experience seamless :

1. Suica or Pasmo Card : This is your absolute must-have! These rechargeable IC cards (similar to Oyster in London or MetroCard in NYC) allow you to simply tap in and out at the gates without fumbling for cash or buying individual tickets. You can purchase them at any station and top them up at ticket machines. They also work on most buses and even some vending machines and convenience stores!

2. Google Maps (or Japan Transit Planner app) : While paper maps are available, your smartphone will be your best friend. Google Maps has excellent transit integration, showing you the fastest routes, transfers, and even platform numbers. Japan Transit Planner (Jorudan or HyperDia are popular alternatives) can offer even more detailed information, especially regarding specific train types (local, rapid, etc.).

3. Know Your Direction : Before you go through the ticket gate, always double-check the platform direction. Stations often have multiple exits, so knowing which one you need can save you time and confusion when you emerge.

4. Mind the Gaps & Etiquette : "Mind the Gap" is a universal subway warning, but in Tokyo, also remember to stand behind the yellow line. When boarding, let passengers exit first. During peak hours, trains can get very crowded, so be prepared to get cozy! Avoid loud phone conversations, eat and drink sparingly (if at all), and keep your voice low.

• Don't Be Afraid of Transfers : Many routes will involve changing lines. Station signage is excellent, with clear arrows and color-coded lines. Just follow the signs for your connecting line.

• Identify Station Codes : Each station has a letter and number code (e.g., Shinjuku Station on the Marunouchi Line is M-08). This can be super helpful, especially if you're not confident with Japanese pronunciation.

• Rush Hour Reality : Between roughly 7:30 AM - 9:00 AM and 5:00 PM - 6:30 PM, the subway can be incredibly packed, especially on major commuter lines. If you can, try to travel outside these times.

• Luggage Lockers : Many major stations have coin lockers where you can store your luggage for a few hours or even a day, freeing you up to explore without being weighed down.

• Enjoy the Experience! People-watching on the Tokyo subway is an art form. Observe the quiet efficiency, the diverse fashion, and the sheer volume of people moving with such precision.
