While Pasmo is primarily issued in the Tokyo region, it works on almost all major train and bus lines throughout Japan due to the "Nationwide Mutual Use" agreement. You can use your Pasmo card seamlessly in cities like Osaka, Kyoto, Sapporo, and Fukuoka on any network that displays the IC card logo (including Suica, ICOCA, and Kitaca areas). It is also accepted at thousands of convenience stores, vending machines, and restaurants across the country. However, there are a few "edge cases" where it will not work: it cannot be used for travel between different IC card zones (for example, you cannot tap in at Tokyo and tap out at Osaka on a local train), and it is not accepted on some very small, private rural lines or long-distance highway buses. For Shinkansen (bullet train) travel, you must link your Pasmo to a specific "Smart EX" or "JR East" account. In 2026, with physical card shortages occasionally occurring, many travelers prefer the Mobile Pasmo on Apple Wallet or Google Pay, which offers the same nationwide compatibility with easier reloading.
