Yes, in 2026, you can still charge (top up) your physical IC card (such as Suica, PASMO, or ICOCA) on most local buses in Japan, but with specific limitations. You typically must wait until the bus is stopped—ideally at a terminal or a long stop—and ask the driver for a "charge" (chāji onegaishimasu). You then place your card on the reader and hand the driver a 1,000 yen note; most bus machines cannot accept larger bills (5,000 or 10,000 yen) for charging. However, with the 2026 push toward mobile integration, it is far more common for travelers to use Mobile Suica or PASMO on their smartphones, which allows you to top up instantly using a digital wallet or credit card without needing the driver's assistance. If your balance is low as you exit the bus, the driver can manually adjust the fare, but they prefer you maintain a sufficient balance to keep the boarding process efficient.
