Public Transport in Japan: Suica, PASMO & Welcome Suica Explained

Tokyo subway station. Public transport in Japan.

If this is your first trip to Japan, here is the good news: you do not need to become a railway scholar before you land. You just need to understand one simple thing: Suica and PASMO are prepaid IC cards. You load money onto them, tap through train gates, tap on and off many buses, and often use them for small purchases too — convenience stores, vending machines, station lockers, and the usual "I need water and a snack immediately" moments.

Now for the part people love to overcomplicate: Suica and PASMO are basically interchangeable for most travellers. Both are part of the same nationwide mutual-use network, which means this is not a high-stakes identity choice.


If you see the IC card symbol, your card will usually work

The real question is not "Which one is superior?" but "Does this specific line or bus actually accept IC cards?"


This is where the tiny Japan travel plot twist enters the chat: IC cards are not universal everywhere. Official guidance from JNTO says some parts of Japan still do not accept IC cards, and not all buses do either. If there is no IC symbol, you may need to pay in cash, and on some non-flat-fare buses that also means taking a numbered paper ticket when you board. So yes, get an IC card — but still keep some cash on you, especially if your plans include rural areas, small local bus routes, and remote detours.


Welcome Suica is the short-term visitor version designed for temporary visitors. It works for 28 days from purchase, requires no deposit, and is simple and convenient for shorter trips. The catch: any remaining balance cannot be refunded at the end of the validity period. It also cannot be used for continuous travel between separate IC areas — if you cross from one area to another, you may need to exit, re-enter, or buy a separate paper ticket. Very handy, but not magic.


Regular Suica or regular PASMO is usually the more sensible option if you are staying longer, expect to return to Japan, or just hate wasting money. Both cards share the same terms: ¥500 deposit, valid for 10 years of non-use, and refundable with a ¥220 handling fee deducted from the remaining balance.


So what actually matters?

Get one IC card, use it wherever you see the IC symbol, and remember that smaller or rural routes may still require cash or a paper ticket. That is the real answer. The brutally simple recommendation:


  • Short trip = Welcome Suica is fine.

  • Longer trip or future return to Japan = regular Suica or PASMO makes more sense.


And if you are heading into quieter corners of Japan, check the actual operator website for the specific line or bus you plan to use — or Google Maps usually tells you too. Public transport in Japan is organised, but it still enjoys the occasional transport ambush.
