Suica, PASMO & ICOCA: A Traveler's Guide to IC Cards

If there is one small piece of plastic (or one tap on your phone) that makes traveling Japan dramatically smoother, it is an IC card. These rechargeable smart cards let you breeze through train gates, hop on buses, and pay at convenience stores with a single tap, no fumbling for coins or decoding fare charts. This guide explains what Suica, PASMO, and ICOCA actually do, whether they are interchangeable, how to add a Suica to your phone, where to buy and top up, and what to do about the well-publicized card shortage.

What IC cards do (and why every traveler wants one)

An IC card is a prepaid, contactless card you load with yen and then tap on a reader. It started as a transit pass but has quietly become a near-universal small-payment tool across Japan. With a single card you can:

Ride trains and subways — tap in at the gate, tap out at your destination, and the correct fare is deducted automatically. No working out the price before you buy a ticket.
Take buses and some trams — most city buses and many regional ones accept IC cards, usually tapping on entry, exit, or both depending on the fare system.
Pay at convenience stores — 7-Eleven, FamilyMart, and Lawson all take IC cards, which is perfect for a quick onigiri, coffee, or bottle of water.
Buy from vending machines and lockers — many drink machines, station coin lockers, and even some restaurant ticket machines accept a tap.
Shop at stations and kiosks — station bakeries, kiosks, and a growing number of shops and cafes accept IC payment.

The appeal for a visitor is speed and simplicity. Instead of recalculating fares at every transfer or hunting for exact change, you tap and go.

Suica vs PASMO vs ICOCA: are they interchangeable?

This is the question that trips up most first-timers, and the answer is reassuring: yes, the major IC cards work almost interchangeably nationwide. The differences are mostly about who issues them and where, not what they can do.

Suica — issued by JR East, most associated with the Tokyo and eastern Japan region.
PASMO — issued by the private railways and subways around Tokyo, functionally identical to Suica for a traveler.
ICOCA — issued by JR West, the card you will most often see around Osaka, Kyoto, and the wider Kansai region.

Thanks to a long-standing mutual-use agreement among Japan's transit operators, a Suica bought in Tokyo works on the subway in Osaka, an ICOCA from Kyoto works on the trains in Tokyo, and so on across the country's main networks. In practice this means you generally only need one card for your whole trip, regardless of which city you start in. Whichever you happen to get first will serve you almost everywhere.

A few small exceptions to know

The nationwide compatibility covers the major networks, but it is not literally everywhere. Some smaller regional rail lines, rural bus operators, and a handful of local systems run on separate or non-IC fare setups, so a card may not be accepted on every obscure branch line. You also cannot use an IC card to ride the shinkansen on a standard tap-in basis the way you would a local train; long-distance bullet train travel uses tickets or dedicated reservation systems instead. For everyday city and suburban travel, though, one card covers the vast majority of what a tourist needs.

Mobile Suica: adding a card to your phone

One of the most convenient upgrades for many travelers is skipping the physical card entirely and using Mobile Suica in your phone's wallet. On a compatible iPhone, you can add a Suica directly to Apple Wallet and top it up with a credit card, then simply hold your phone near the gate reader. Recent Android phones with the right hardware can use Mobile Suica through Google Wallet as well.

The advantages are obvious once you try it: no card to buy at a machine, no queueing to recharge, and you can top up your balance from anywhere in seconds. There are a couple of practical points to keep in mind:

You need an internet connection to set it up and reload. Adding Suica to your wallet, registering a payment card, and topping up all happen online, so you want data the moment you want to load money. This is one of those small but real reasons a working connection matters from the start.
Device compatibility varies. Apple devices have supported Suica in the wallet for years, while Android support depends on the specific phone and region, so check before you rely on it.
The card lives on one device. A mobile IC card is tied to the phone you set it up on, so plan around the device you will actually carry each day.

Because every part of the mobile setup runs over the internet, it is worth having data ready before you start tapping. A Japan eSIM plan gives you that connection from the moment you land, so you can add Mobile Suica and reload it on the train rather than hunting for WiFi at the airport. For a fuller rundown of the apps and connectivity that make this seamless, see our guide to staying connected in Japan with free WiFi, maps, and travel apps.

Where to buy and top up a physical card

If you prefer a physical card, you can typically obtain one at ticket machines and ticket offices in major train stations, including at the big arrival airports. The machines have an English-language option, and the process is straightforward: choose to buy a new IC card, insert cash, and collect the card preloaded with whatever balance you selected.

Topping up (charging) is just as easy and almost always done with cash:

Find any IC card charging machine or fare-adjustment machine in a station, switch to English if needed, insert your card, and add yen in set increments.
Some convenience store registers can also recharge your card when you pay.
Keep a little cash on hand specifically for topping up, since many recharge machines do not take foreign credit cards. Our guide to money in Japan: cash, cards, and budgeting explains where cash is still king and why carrying some yen remains essential.

The IC card shortage and current workarounds

One thing to be aware of: due to a global shortage of the semiconductor chips inside the cards, sales of some standard physical IC cards have at times been suspended or limited, particularly the regular unregistered Suica and PASMO in the Tokyo area. This situation has been evolving, so the practical advice is to stay flexible:

Use Mobile Suica if your phone supports it. The mobile version sidesteps the physical-card shortage entirely, which is part of why it has become so popular.
Consider a tourist-specific card (covered below), which has often remained available when standard cards were limited.
A different regional card may still be on sale even if your first choice is not, and since they are interchangeable nationwide, that is a perfectly good substitute.
Check the latest before you go. Because availability shifts, it is worth confirming the current situation on official transit operator pages rather than assuming.

Welcome Suica and tourist options

Japan offers a few cards aimed specifically at short-term visitors. The best known is the Welcome Suica, a tourist version that is typically sold without the usual refundable deposit and is valid for a set window (commonly around four weeks) from the date of purchase. There are comparable tourist-oriented ICOCA products in the Kansai region as well.

These tourist cards work just like a standard IC card for tapping through gates and paying for small purchases. The main trade-offs to understand:

Limited validity. Because they are designed for visitors, they expire after their set period, which is usually fine for a normal holiday but worth noting.
No deposit to reclaim. You skip the deposit on the way in, which also means there is nothing to refund on that front when you leave.
Often easier to find. When standard cards have been scarce, these tourist versions have frequently remained available at airport and major-station counters.

Refunds and your leftover balance

What about the yen still sitting on your card when your trip ends? You have a few sensible options:

Spend it down. The simplest approach is to run the balance low before departure by buying snacks, drinks, or souvenirs at convenience stores and station shops, since IC cards work for everyday purchases, not just transit.
Refund a standard card. Regular (non-tourist) IC cards can generally be refunded at the issuing operator's ticket office. Be aware that a handling fee is often deducted, and any refundable deposit is returned, so the economics depend on your remaining balance.
Keep it for next time. Standard IC cards stay valid for a long period and do not expire quickly, so if you expect to return to Japan, simply holding onto the card and its balance is often the most painless choice.

Tourist cards like the Welcome Suica follow their own rules, and their leftover value typically is not refunded in cash, which is another reason to spend the balance down before you fly. When in doubt, the issuing operator's ticket office is the place to sort out refunds.

An IC card is one of the great quiet conveniences of a Japan trip, turning the country's dense transit network into a simple tap-and-go experience and doubling as your wallet at the konbini. Whether you carry a physical Suica, PASMO, or ICOCA or load one onto your phone, the key is having it ready before you are standing at the gate. And since adding and reloading Mobile Suica all happens online, a Japan eSIM that connects the moment you land lets you set it up on the move, keeping you online for the maps, train times, and payments that make getting around Japan so effortless. For the full connectivity setup, our complete Japan eSIM guide covers installation and activation from start to finish.

Frequently Asked Questions

Are Suica, PASMO, and ICOCA interchangeable in Japan?

Yes. Thanks to a nationwide mutual-use agreement between Japan's transit operators, the major IC cards work almost interchangeably across the country's main rail and subway networks. A Suica bought in Tokyo works on trains in Osaka, and an ICOCA from Kansai works in Tokyo. In practice you only need one card for your whole trip, though a few small regional lines and rural buses may run on separate systems.

Can I add Suica to my iPhone or Android phone?

Yes. On a compatible iPhone you can add a Suica to Apple Wallet and top it up with a credit card, then tap your phone at the gate. Recent Android phones with the right hardware can use Mobile Suica through Google Wallet too. Setting it up and reloading both require an internet connection, so it helps to have mobile data ready as soon as you arrive.

Can I still buy a Suica or PASMO with the card shortage?

A global chip shortage has at times suspended or limited sales of standard physical Suica and PASMO cards, especially in Tokyo. Workarounds include using Mobile Suica on your phone, buying a tourist-specific card like the Welcome Suica, or getting a different but interchangeable regional card such as ICOCA. Availability keeps changing, so check official transit pages before you travel.

How do I top up an IC card in Japan?

Use any IC charging or fare-adjustment machine in a train station, switch it to English if needed, insert your card, and add yen in set increments. Some convenience store registers can also recharge your card at checkout. Recharging is almost always done with cash, and many machines do not accept foreign credit cards, so keep some yen on hand for topping up.

Can I get a refund for the leftover balance on my IC card?

Standard (non-tourist) IC cards can usually be refunded at the issuing operator's ticket office, though a handling fee is often deducted and any deposit is returned. Many travelers simply spend the balance down at convenience stores before leaving, or keep the card for a future trip since standard cards stay valid for years. Tourist cards like the Welcome Suica generally are not refunded in cash, so spend those down first.
