The Suica can be loaded and used as many times as desired. The Suica can be loaded up to a maximum of 20,000 yen at Automatic Ticket Vending Machines and Fare Adjustment Machines displaying the Suica mark. Only yen may be used to load a card.

The Suica card, Japan’s iconic "tap-and-go" smart card, has a maximum balance limit of 20,000 yen (approximately $135 to $150 USD). This limit is a security measure designed to minimize the financial loss if a physical card is lost or stolen, as "Anonymous" cards cannot be easily blocked or refunded. In 2026, the same 20,000 yen limit applies to "Mobile Suica" on Apple Wallet and Google Pay. While you can only hold 20,000 yen at once, there is no limit to how much you can spend in a single day, provided you keep topping it up. You can add funds at ticket machines (using cash) or via a linked credit card on your smartphone. It is important to note that you cannot use Suica for single transactions exceeding 20,000 yen; if you are buying a high-end electronics item or a long-distance Shinkansen ticket, you will likely need to use a standard credit card or cash instead. For the average traveler, 20,000 yen is more than enough for several days of local subways, convenience store snacks, and vending machine drinks.
