Introduction: The Card That Runs Your Entire Trip
IC cards (ICカード) — rechargeable contactless smart cards used for transit payment throughout Japan — are the single most practically useful piece of technology for navigating Japan. A single IC card allows you to board trains, subways, buses, and ferries in virtually every metropolitan area in Japan, pay for purchases at convenience stores, vending machines, and an increasing range of retail shops, and — in the case of the JR East Mobile Suica — manage everything from a smartphone wallet.
Are They Actually Different?
For most practical purposes of a tourist traveling through Japan: no. All major IC cards are accepted on all major transit systems throughout Japan through the nationwide IC card interoperability agreement. A Suica purchased at Narita Airport works on Kyoto's subways, Osaka's buses, and Hiroshima's streetcar.
The functional difference matters primarily for:
Season passes and commuter discounts (only the local card works for these)
Specific airport access trains (a few exceptions exist in special cases)
The issuing railway's own bonus programs
- For tourists: Buy whichever card is available at your first arrival airport and use it throughout Japan.
Getting a Suica (The Tourist's Standard Choice)
Suica has become the de facto tourist standard because JR East operates Narita Airport and Haneda Airport, making it the first card most international arrivals encounter, and because Mobile Suica (モバイルSuica) is available as a digital wallet for iPhone and Android, allowing foreigners with overseas credit cards to add money via Apple Pay or Google Pay.
Physical Suica:
Available at JR East ticket machines at all major JR East stations
¥500 deposit (refundable on return at JR East stations)
Minimum initial load: ¥1,000
Maximum balance: ¥20,000
Mobile Suica (iPhone / Android):
Available via the Suica app or within Apple Wallet (iPhone)
No physical card or deposit required
Top-up via credit card including foreign cards in many cases
The most convenient option for smartphone-dependent travelers
Welcome Suica (ウェルカムSuica): A special card for tourists — no deposit, valid for 28 days, available at specific airport vending machines and tourist information centers. Slightly more convenient for short visits (no deposit to worry about reclaiming).
Using IC Cards
Transit: Tap on entry, tap on exit — the card deducts the correct fare automatically. No need to calculate fares or understand zone systems.
Purchases: Look for the IC card symbol (a small radio wave logo) at convenience stores, vending machines, and other retail — tap to pay.
Low balance: Most gates will reject an IC card below approximately ¥20 — top up (チャージ / chāji) at any station machine that accepts your card.
Refunding: Physical Suica can be refunded at JR East stations — present the card and receive the remaining balance minus ¥220 handling fee, plus the ¥500 deposit.
