A ticket gate clicks open, a vending machine in the corridor glows with rows of canned coffee, and somewhere in the line behind you, people are tapping a card or a phone against a blue reader without breaking stride. That is usually the moment a visitor wonders whether the card can live on a phone instead of in a wallet. Suica has a mobile version made for visitors, called Welcome Suica Mobile, and this is how it fits with the plastic cards around it.

Can you add Suica to an iPhone?
Suica does have a version for phones aimed at foreign visitors, named Welcome Suica Mobile, and JR East publishes the information about it on its own website.
Suica is a prepaid, rechargeable, contactless smart card and electronic money system. It began as a fare card on JR East train lines and grew into something used for much more than trains. On a phone or in a wallet, it is the same idea: you put money on it, you touch it to a reader, and the fare or the purchase is deducted.
Three versions you will run into
A regular Suica is the card sold to anyone, and it carries a deposit. Welcome Suica is the version for international tourists, and it carries no deposit. Next to them sits TOURIST PASMO, another deposit-free card for foreign visitors, with information on the PASMO website for visitors.
Names matter here because a search for a Suica app turns up several things that sound alike. Welcome Suica, Welcome Suica Mobile and plain Suica are separate products with different rules about deposits and how long they last.
Why a visitor might prefer the phone
A card in a phone case is one thing less to dig out at a ticket gate, and a phone is the object travelers already keep within reach. It also means no stop at a machine or a service window to pick up plastic. The phone version still follows the tourist-card rules, so it is built around a short stay rather than years of use.
If your trip involves several regions, the card does not tie you to Tokyo. Most regions have their own IC cards with different names and mascots, yet these cards can be used throughout Japan, and Suica works as part of that nationwide mutual usage arrangement.
Card or phone: how the options compare
| Card | Deposit | Validity |
|---|---|---|
| Welcome Suica | None | 28 days from the date of purchase |
| Welcome Suica Mobile | None | 28 days |
| Regular Suica | 500 yen | Expires ten years after last use |
| TOURIST PASMO | None | Not specified |
The table lists only what is certain. Welcome Suica runs out for good at the end of its 28 days, while a regular Suica stays alive as long as it is used now and then. For a trip with a clear start and end, the tourist versions are built for exactly that shape.
How does it work?
Suica works as a prepaid balance: you load money, touch the card or phone to a reader at a gate or a register, and the amount is taken off. Nothing is billed afterward, and when the balance runs low you add more.
It was launched by JR East on November 18, 2001, at 424 stations. Since then the system has widened well past its first stations. It can be used on trains, buses and boats, in vending machines, in convenience stores, in some taxis and for other services, so one balance covers a day of moving and snacking.
On trains, trams and buses
Suica is accepted on virtually any train, tramway or bus system in the Greater Tokyo Area. Through the Nationwide Mutual Usage Service it also reaches many other parts of the country.
The routine is simple to picture: touch in at the gate where you enter, touch out where you leave, and the fare is worked out between the two. On a bus, you touch at the reader as you board or step off, depending on the bus.
Suica and Welcome Suica also let you use some discount tickets. Which ones depends on the ticket itself, so it is worth reading what a particular discount ticket says about IC cards.
In shops, kiosks and taxis
Suica is widely used as electronic money, especially at convenience stores, chain restaurants and shops inside train stations. A station kiosk with newspapers and bottled tea, a rice-ball shelf in a convenience store at the end of a long day, a coffee at a counter before a connection: these are the small purchases the card was made for.
Chains that support transactions with Suica include FamilyMart, 7-Eleven, Lawson, Yodobashi Camera, Bic Camera, Doutor Coffee, CoCo Ichibanya and MOS Burger. Many shops at airports, and taxis throughout Japan, also accept Suica payment. That means the same balance can pay for a curry at a CoCo Ichibanya, a burger at MOS Burger or a gadget at an electronics store.
Child fares and commuter passes
Child versions of Suica charge half fares. A Suica may also hold a commuter pass for one, three or six months along a specified route between two designated stations. Both are features of the regular card system and mostly matter to residents, but they explain why the card has so many varieties.
What do you need?
What you need depends on the version: a regular Suica needs a 500 yen deposit at purchase, while Welcome Suica and TOURIST PASMO need no deposit at all. Beyond that, you need money to load and a place to get the card or, for Welcome Suica Mobile, the information on the JR East website.
The deposit and the refund
Most IC cards in Japan require a 500 yen deposit at the time of purchase, and Suica is one of them. The remaining balance on a Suica card can be refunded. The tourist versions skip the deposit, which is why they are described as made for visitors.
Think of the deposit as a loan for the plastic. For a visitor with a few days in Japan, a card with no deposit means there is nothing to get back at the end, and nothing to forget about.
Where Suica cards are sold
Suica cards are available at ticket vending machines or customer service windows at all JR East train stations. A visitor who wants the physical Welcome Suica will find its details on the JR East website, and PASMO publishes a page for visitors and one for TOURIST PASMO.
That is where to look for the phone requirements and the steps to follow, since they are set by the issuer.
How long it lasts
Welcome Suica can only be used for 28 days from the date of purchase, after which it expires permanently. A regular Suica expires ten years after its last use. For a trip of one or two weeks, the 28 days cover everything with room to spare. For someone planning a long stay or several trips, the difference between the two cards is worth a thought.
Good to know before you go
Money in Japan is counted in yen, and a Suica balance is yen too, so what you load is what you spend. The deposit on a regular card is 500 yen, refundable along with the remaining balance, and Welcome Suica has none.
Because Suica works in so many small places, from vending machines to convenience stores to some taxis, a loaded balance covers many of the little purchases of a day. Another IC card from a different region works across the country as well, so a card you already hold keeps its use as you travel.
