The IC card (Integrated Circuit card) is the single most useful item a Japan traveler can carry — a rechargeable contactless card that works on virtually every train, subway, bus, and monorail in Japan, as well as at convenience stores, vending machines, coin lockers, and taxis. Understanding how to get and use one immediately removes a significant friction point from Japan travel.
Suica & Pasmo
Suica (issued by JR East) and Pasmo (issued by Tokyo Metro and private railways) are the two main IC cards for the Tokyo area — they are mutually compatible and interchangeable for all payment purposes. Either works on every train, bus, and payment terminal in Japan that accepts IC cards (effectively all of them). ICOCA (JR West, Osaka) and Manaca (Nagoya) are regional alternatives that work nationally with the same compatibility. For visitors: buy a Suica at any JR East ticket machine (including Narita/Haneda airports) — the process is fully English-language supported. Initial purchase: ¥500 deposit (refundable) + desired charge (¥1,000–10,000). Recharge at any ticket machine, convenience store, or mobile app.
What IC Cards Pay For
IC cards cover: all urban rail (JR, Metro, private railways, monorails, trams); airport limousine buses; local buses in most cities; coin lockers at train stations; vending machines (nearly all); convenience stores (7-Eleven, Lawson, FamilyMart, etc.); fast food (McDonald’s, MOS Burger, most chains); some taxis (look for the IC mark on the vehicle). IC cards do NOT work on: Shinkansen (requires separate ticket or JR Pass); overnight express trains; most domestic airlines; restaurants without IC terminals (carry ¥1,000 notes as backup).
Mobile Suica
Mobile Suica on iPhone (Apple Pay) or Android (Google Pay/Suica app) allows using a smartphone as an IC card — no physical card needed. Works on iPhone models from iPhone 7 onwards; setup requires an Apple ID but no Japanese address. The mobile card can be topped up via credit card (international cards accepted). The convenience of not needing a separate card is significant for travelers who prefer to travel light. Note: foreign-issued credit cards added to Apple Pay for Suica topping are occasionally declined — have a backup top-up method.
- Never let your IC card balance drop to zero on a barrier-controlled railway — you cannot pass through the gates; recharge before entering.
- The ¥500 deposit is refunded when returning the card at a JR East office — worth doing if leaving Japan for a significant period.
- IC cards can be used as luggage claim tokens at major airports’ coin lockers — much more convenient than cash lockers.
