Tokyo's rail network moves more people than any other on earth and it is, genuinely, easy. The confusion visitors have isn't about the trains. It's about the tickets, and about one expensive product sold hard to tourists who don't need it.
Get an IC card, tap everything, stop thinking about it
Buy a Suica or Pasmo at the airport or any station. They're identical for your purposes — a stored-value card you tap on the way in and out.
It works on JR lines, Tokyo Metro, the Toei subway, private railways, buses, and — the part people miss — most convenience stores, vending machines and plenty of small shops. Top it up at any machine.
That's the entire system. You never work out a fare, never buy a ticket, never worry about which company owns which line. Fares run roughly ¥150–320 a ride.
Both cards work in most other Japanese cities too, so it keeps earning after Tokyo.
You almost certainly don't need a JR Pass
This is the one that costs people money.
The nationwide Japan Rail Pass is designed for intercity travel — it's priced against long shinkansen journeys, and it only pays off if you're doing several of them. Tokyo to Kyoto and back is roughly the break-even point, and after the 2023 price increase even that is marginal.
Inside Tokyo it's close to useless. It covers JR lines only — so the Yamanote loop, yes, but not the Tokyo Metro, not the Toei subway, not the private railways that reach Shimokitazawa or Nikko. You'd be paying a large fixed sum for partial coverage of a network where individual fares are already cheap.
Buy a JR Pass if: you're doing Tokyo → Kyoto → Hiroshima → Tokyo, or something of that shape. Don't buy one if: you're staying in and around Tokyo, even with a day trip or two.
The lines actually worth knowing
The Yamanote line is the loop, and it's the spine of the city. Shinjuku, Shibuya, Harajuku, Shinagawa, Tokyo, Akihabara, Ueno, Ikebukuro — all on it. If you can find the Yamanote, you can find your hotel. Riding it the whole way round takes about an hour and is the best orientation Tokyo offers.
The Ginza and Marunouchi lines cover the central metro gaps the loop doesn't reach.
The Chuo line cuts straight across the middle of the loop, which saves real time going east–west.
Everything else you can look up when you need it.
Google Maps is unusually good here
Better than it is in most cities, because the data is better. It will give you the platform number, the departure minute, and often which carriage to board so you're nearest the exit stairs at the far end. Trust it.
The one thing it can't help with is Shinjuku Station, which has more than 200 exits. Note the exit name before you surface, and expect to get it wrong at least once.
The last train is a real constraint
Services stop somewhere between midnight and 1am depending on the line, and don't restart until around 5am. There is no night service.
This shapes Tokyo nights more than visitors expect. Locals either leave in time or stay out until the trains restart — which is why there are so many bars, karaoke rooms and 24-hour cafés. Missing it means a taxi, and Tokyo taxis are clean, honest and genuinely expensive; a cross-city fare can exceed ¥8,000.
Taxis, buses, and walking
Taxis are excellent and pricey. The doors open automatically — don't grab the handle. Most drivers speak no English, so have your destination written down or on a map.
Buses are cheap and fill the gaps between stations, but the routes are hard to parse and the announcements are in Japanese. Fine with Google Maps, unnecessary otherwise.
Walking is underrated. Tokyo is too big to walk between districts and perfect to walk within one. The city rewards picking a small area and covering it on foot.
From the airport
Narita is 60–90 minutes out. The Narita Express goes to Tokyo, Shinjuku and Shibuya; the Keisei Skyliner is faster and cheaper to Ueno. Both fine, both far better than a taxi.
Haneda is much closer — 30 minutes to central Tokyo on the monorail or the Keikyu line. If you have a choice of airport, this one is worth a small premium.
Buy your IC card at the airport before you do any of it. Everything after that is tapping through a gate.
Frequently Asked Questions
Do I need a JR Pass for Tokyo?
Almost certainly not. The nationwide pass is priced for intercity travel and only pays off across several long shinkansen journeys — roughly Tokyo–Kyoto and back is break-even, and marginal even then since the 2023 price rise. Inside Tokyo it covers JR lines only, not the Tokyo Metro, the Toei subway, or the private railways, so you'd pay a large fixed sum for partial coverage of an already cheap network.What is the difference between Suica and Pasmo?
For a visitor, nothing. Both are tap-to-pay stored-value cards that work on JR, Tokyo Metro, Toei, private railways and buses, plus most convenience stores and vending machines. Buy whichever the machine in front of you sells, and top it up at any station.Which train line is most useful in Tokyo?
The Yamanote line — the loop that connects Shinjuku, Shibuya, Harajuku, Shinagawa, Tokyo, Akihabara, Ueno and Ikebukuro. If you can find the Yamanote, you can find your hotel. Riding it all the way round takes about an hour and is the best orientation the city offers.What time do trains stop running in Tokyo?
Between roughly midnight and 1am depending on the line, restarting around 5am. There's no night service. Missing the last train means a taxi, and a cross-city fare can exceed ¥8,000 — which is why Tokyo has so many late bars, karaoke rooms and 24-hour cafés.Should I fly into Narita or Haneda?
Haneda if you have the choice. It's about 30 minutes from central Tokyo on the monorail or the Keikyu line, against 60–90 minutes from Narita. It's often worth a small premium.
