IC Cards Are the One Piece of Plastic That Runs Japan
The first hour in Japan usually involves standing at a ticket machine trying to work out the fare to a station you can't yet pronounce, while a queue forms behind you. There is a way to never do this again, and it costs about the price of a coffee: a rechargeable IC card that you tap on the way in and tap on the way out, and which also happens to pay for your convenience store lunch.
They're Regional Brands of One System Suica belongs to JR East, ICOCA to JR West, Pasmo to Tokyo's private railways, and there are half a dozen more — Toica, Manaca, Kitaca, Sugoca, Hayakaken, Nimoca, Pitapa. Since a mutual-use agreement, almost all of them work almost everywhere the others do, so which one you buy matters far less than having one at all. A card bought in Tokyo will get you through the gates in Fukuoka.
What It Actually Replaces On trains and subways you stop calculating fares entirely: tap in, tap out, correct fare deducted. Most city buses take the same card, usually tapping on entry and exit. Beyond transport it works as small-value electronic cash at convenience stores, station kiosks, vending machines, many chain restaurants and coin lockers — which quietly solves the problem of accumulating ¥1 coins.
Where It Doesn't Work IC cards do not pay for shinkansen fares in the normal way, and they don't work on limited express reserved seats — those still need tickets or a separate online reservation. There are also stretches of rural line, particularly in parts of Tōhoku, Shikoku and Kyushu, where the local trains are outside the IC area entirely and you take a paper numbered ticket from a machine by the door. Crossing between two IC regions in a single journey can also confuse the gates, so it's safer to buy a ticket for long inter-regional local trips.
On Your Phone, or in Your Hand Suica and Pasmo can live in an iPhone or Apple Watch wallet and be topped up with a foreign credit card, which is genuinely the smoothest option — no deposit, no physical card, and you can recharge on the platform. Physical cards are bought from station machines with a small refundable deposit, and are recharged with cash. Note that availability of the unregistered physical cards has been restricted at times due to chip shortages; the phone version has no such limit.
The Welcome Versions Short-stay visitors can also buy tourist variants — Welcome Suica and ICOCA versions aimed at travellers — which skip the deposit but expire after 28 days. If you're here for a fortnight, that's simpler; if you expect to come back, a normal card keeps its balance for years.
They Are Not Just for Trains The part visitors underuse is that an IC card is a general-purpose small-payments wallet. Convenience stores, vending machines, supermarkets, most chain restaurants, station lockers, many taxis and a good number of independent shops all take it, and the transaction is a single tap with no PIN and no signature.
This matters more than it sounds because it solves the coin problem. Japan still runs on cash in a lot of places, and cash here means an accumulating handful of one-, five-, ten-, fifty-, hundred- and five-hundred-yen coins that will otherwise weigh down your pocket for a fortnight. Paying by IC card for small things is the simplest way not to generate them.
The Regional Cards Are Interchangeable There are ten major cards — Suica and Pasmo in Tokyo, ICOCA in the Kansai region, and others issued by the regional rail companies — and for practical purposes they are mutually usable. A Suica bought in Tokyo works on the Osaka subway and in a convenience store in Fukuoka.
The exception is worth knowing: some rural private lines and local buses sit outside the network entirely, and a handful of areas run their own local card instead. This is not a reason to buy several cards. It is a reason to keep some cash for the day you go somewhere small.
Where It Will Not Help You An IC card pays fares; it does not buy reserved seats. Shinkansen and limited express services need a separate ticket, bought online or at a machine or counter, and tapping through a local gate with an IC card is not a substitute. There are integrated schemes that link a card to a booking on some routes, but the safe assumption is that anything with a seat number is a separate transaction.
One more limitation catches people out: you cannot go into negative balance at an exit gate on most journeys, so a long ride on a thin balance ends with you at a fare adjustment machine. Topping up in larger amounts than feel necessary avoids that entirely.
- 1Set up a digital Suica or Pasmo in your phone wallet before you land and top it up with a credit card. No deposit, no queue, and you can recharge on the platform.
- 2Load more than you think you need. Most gate-side charging machines take cash only, and a thin balance at an exit gate means a trip to the fare adjustment machine.
- 3Use it for coffee, lockers and convenience stores, not just trains. It is the simplest way to avoid accumulating a pocket of coins.
- 4One card covers the whole country. A Tokyo Suica works in Osaka and Fukuoka, so do not buy a second one at each new city.
- 5Buy shinkansen and limited express seats separately. IC cards pay fares; they do not reserve seats.
- 6Keep some cash for rural buses and small private lines, which sit outside the network.
The IC card is one of three or four small decisions that quietly determine how smooth a Japan trip feels, alongside luggage forwarding, knowing where cash is still mandatory, and whether a rail pass is worth it for your route. Our trip planning guides cover each of those in turn, and they are free.
