Yes, Pasmo is one of the most widely accepted IC cards for buses across Japan, particularly in the Greater Tokyo area. As part of a nationwide integration program, Pasmo is interchangeable with other major cards like Suica, ICOCA, and Toica. You can use it on almost all city buses, including Toei Buses in Tokyo, and many private bus lines. To pay, you simply "tap" your card or mobile device against the IC reader (usually located near the driver or the entrance/exit doors). In Tokyo, most buses have a flat fare where you only tap once upon boarding, but in other regions where fares are based on distance, you must tap when entering and again when exiting. As of 2026, while physical Pasmo cards are increasingly replaced by mobile versions for residents, the card remains a reliable "all-in-one" payment method for both transit and small purchases at vending machines and convenience stores throughout the country.
