I Finally Cracked the Tokyo Subway System (And It’s Easier Than I Thought)

Back in 2023, my son and I took a round the world trip, and as part of that trip, we spent a few days in Tokyo. Although I don’t personally live in a city that has a subway system (thanks Great Depression!), I have traveled on public transit and subways a lot of times. I took a bus in Morocco to avoid cheating taxi drivers. I’ve lost a kid on the subway in Barcelona. Still, something about the Tokyo subway system really did not click for me.

We didn’t get hopefully lost or anything, but there were definitely a few things that I didn’t quite understand. My wife and I returned to Tokyo in April 2026, and after using the subway and rail systems in Tokyo, I think I finally have figured out what is going on.

The Biggest Thing I Didn’t Understand: Tokyo Has Multiple Train Companies

The “Tokyo subway system” isn’t actually one unified system. Instead, like in London and New York City, the different rail lines were all built by different companies, so there is not a single subway system. Instead, you might ride on one or more of any of the following.

• Tokyo Metro
• Toei Subway
• JR East
• Private railways like Keio, Odakyu, Tokyu, etc.

This was the root of most confusion in the original article and comments. Since trains can run seamlessly across different companies, it makes it feel like one network even though it isn’t.

Why Google Maps Solves 95% Of The Problem

I had used Google Maps last time, but it was a bit trickier because I think I didn’t have a data plan in Japan. This time, we did have data (an Airalo e-sim was super convenient and cheap), so we were able to access Google Maps during our whole trip. Google Maps transit directions will tell you things like the exact platform numbers to use, train line names/colors, transfer times, and exit numbers. So instead of trying to memorize the entire system, just trust Google Maps and follow the instructions.

The Real Secret Is Learning Station Exits

Tokyo has some massive stations, like Tokyo Station, Shinagawa Station or Shinjuku Station. Shinjuku Station alone has over 1 billion passengers a year, and is frankly more like a small city than a rail station. Shinjuku Station also has over 200 exits! On my 2023 trip, I walked 10 minutes underground the wrong way, because I was following the wrong exit sign. This time, I had figured out to pay closer attention to the exit to take (thank you Google Maps!) and managed to avoid that problem.

When we first arrived at Shinjuku Station on our way to the Hyatt Regency Tokyo, we exited aboveground and walked the 15 minutes, but later I found that there was actually a way to go from Shinjuku Station to the Hyatt Regency Tokyo completely underground! Walking 15 minutes through the Shinjuku Station complex only to pop up aboveground right in front of our hotel made me feel like a total Tokyo subway pro.

IC Cards Make Transfers Feel Invisible

Another issue we had on our 2023 trip was paying for tickets. In the olden days, you used to have to actually buy paper tickets to ride the subway. This made it incredibly complicated since as we mentioned above, there are different rail companies, so switching between the Tokyo Metro and the JR Line, for example, would mean you’d have to buy 2 different tickets.

Now everything uses the Pasmo or Suica cards. In 2023, we had to get a physical Pasmo card, because my son and I both had Android phones and Google Pay (at the time) did not work for paying for tickets. Now, we have iPhones, and so it was easy to get a virtual Pasmo card on our phones and load and reload it. We actually loaded our phones with 5,000 JPY before we left for Japan, and it turned out that we made it to our flight to Honolulu with only JPY 55 left on our cards, so we never even had to reload.

The process of tapping in and out was super easy – we just used our phone at each turnstile. The Tokyo subway system would automatically calculate the fares including any transfers. We had no issues except for once or twice the phone wouldn’t scan at the turnstile, but even then, the system seemed to figure out everything correctly.

The Bottom Line

So I still think Tokyo transit can feel overwhelming at first. But now I understand that t’s multiple systems working together, Google Maps does the heavy lifting, and exit numbers are the hidden key. Tokyo transit now feels logical instead of chaotic. The challenge is the scale and density of the travel, not any sort of bad design. After several days, recognizing line colors, symbols, and patterns becomes second nature. You do not need to master the entire system before visiting Tokyo.
After a few days, you will probably “crack the code” too!
