In 2026, the PASMO card is exceptionally versatile, but it is not "universal" in the strictest sense. While it is primarily associated with Tokyo's private railways and subways, it is part of Japan’s Nationwide Mutual Usage system. This means you can use PASMO on almost all major trains, subways, and buses in cities like Osaka, Kyoto, Nagoya, and Fukuoka (wherever you see the IC logo). However, it generally cannot be used for travel between different regions (e.g., you can't tap in at Tokyo and tap out at Osaka). Furthermore, very rural areas or small independent bus lines in deep countryside regions may still only accept cash. Beyond transit, PASMO is a high-value "digital wallet" accepted at millions of convenience stores, vending machines, and restaurants nationwide. As of 2026, most travelers prefer the Mobile PASMO on their phones to avoid the physical card shortage and the ¥500 deposit fee.
