Japan's essential IC card for trains, subways, buses, and purchases at convenience stores and vending machines. The physical Welcome Suica expires after 28 days with no refund on remaining balance.
Japan: Add Suica to Apple Pay for tap-and-go on virtually every transit system. Android users need a physical card since mobile Suica requires Japan-sold phones with FeliCa hardware, and the Welcome Suica app is iOS only.
