Why Can One Card Pay for Trains, Buses, Taxis, and Convenience Stores in Japan?
Key Insight
Japan's IC cards like Suica and PASMO use FeliCa contactless chip technology — the same standard across every transit operator and retailer — so a single tap works nationwide at over 850,000 locations.
📖 Explanation
One Card, the Whole Country
Suica (JR East) and PASMO (Tokyo Metro and private railways) look like ordinary transit cards, but they run on Sony's FeliCa NFC chip — a standard that every major Japanese transit operator agreed to adopt in the early 2000s. Because the underlying protocol is identical, a card issued by JR East works seamlessly on Osaka's subway, Kyoto's buses, and even airport monorails.
Why Retail Accepts It Too
In 2004, JR East opened the FeliCa payment network to retailers under the Suica e-money brand. Convenience stores like 7-Eleven and FamilyMart saw the opportunity: customers already carried the card, the tap-to-pay transaction completes in 0.1 seconds (faster than any QR code), and charge-back fraud is near zero. Over 850,000 stores now accept IC card payments.
How to Get One as a Tourist
Since 2023, a mobile Suica can be loaded onto iPhone or Android before you even land. Physical cards are available at any airport JR ticket machine with a ¥500 deposit. Load ¥3,000–¥5,000 for a week of travel — trains, buses, coffee, and snacks all handled with one tap.
❓ Frequently Asked Questions
- Can I use Suica outside Tokyo?
- Yes. Suica and PASMO are accepted on most transit networks across Japan, including Osaka, Kyoto, Nagoya, Fukuoka, and Sapporo, as well as the Shinkansen (IC-designated seats only).
- What happens to unused balance when I leave Japan?
- You can refund the remaining balance plus the ¥500 deposit at any JR ticket machine. Mobile Suica balance can be transferred to Apple Pay or Google Pay for future visits.
- Is Suica the same as a credit card?
- No. Suica is a prepaid card — you load money in advance and spend from that balance. It does not involve a credit check and works without internet at point of sale.
- Where can I buy a Suica as a tourist?
- Welcome Suica (no deposit, 28-day validity) is sold at Narita and Haneda airport JR ticket counters. Regular Suica with ¥500 refundable deposit is available at any JR East ticket machine.
