Yes, as of 2026, the PASMO card (along with Suica and Icoca) is part of a nationwide "Interoperation" system, meaning it can be used on virtually all major trains, subways, and buses across Japan. Whether you are in Tokyo, Kyoto, Osaka, or even smaller cities like Fukuoka or Sapporo, your PASMO card will work at the ticket gates. It is also a high-value "digital wallet" for convenience stores (7-Eleven, Lawson), vending machines, and even some taxis and lockers. However, there are two major exceptions: you cannot use it for long-distance Shinkansen (bullet train) tickets without specific pre-registration, and you cannot use it to travel between two different IC regions (e.g., you can't start a journey in a "PASMO" zone and end it in an "Icoca" zone on a single tap). In 2026, most travelers now use the Mobile PASMO on their Apple or Google Wallets for seamless, instant top-ups via their phones.
