In 2026, paying for transportation in Japan is primarily handled via IC cards (integrated circuit cards) or increasingly through contactless mobile payments. The most popular IC cards are Suica and Pasmo (in Tokyo) and ICOCA (in Osaka), which are all interchangeable nationwide. You simply tap your card—or your smartphone/watch using Apple Pay or Google Pay—on the reader at the ticket gate. For tourists, the Welcome Suica (both physical and mobile) is the gold standard, as it requires no deposit and is valid for 28 days. In 2026, many major cities have also introduced direct contactless payment (EMV) at ticket gates, allowing you to use a standard Visa or Mastercard from your home country without a local card. For long-distance travel like the Shinkansen, you can purchase "Paperless" tickets via the SmartEX app or buy physical tickets at the station's "Midori-no-Madoguchi" kiosks. While cash is still used at smaller regional stations to "top up" cards, the Japanese transit experience has become almost entirely "tap-and-go" for the modern traveler.
