Yes, in 2026, the Suica card (issued by JR East) is fully compatible with the transit systems in Kyoto through the nationwide IC card integration. You can use Suica to pay for almost all local transportation in Kyoto, including the Kyoto City Subway, private railway lines like Keihan and Hankyu, and the extensive Kyoto City Bus network. Simply tap your card on the reader when entering and exiting stations or boarding buses. Furthermore, Suica is widely accepted at convenience stores, vending machines, and many restaurants throughout the city. However, there are two important limitations to remember in 2026: you cannot use Suica to pay for the Shinkansen (bullet train) between Tokyo and Kyoto unless it is linked to a "SmartEX" account, and if you run into technical issues with the card, you can only get a refund or formal service at a JR East station (like those in Tokyo), not at a JR West station in Kyoto.
