Yes, it can. Suica cards can be used anywhere the Suica IC card logo is displayed. It can also be used in convenience stores and vending machines outside of the Tokyo area. You cannot use the Suica to travel between Tokyo and Osaka, but you can use it to travel within cities such as Osaka and Kyoto.

Yes, you can use your Suica card for local travel in both Tokyo and Osaka, but you cannot use it for the entire journey between the two cities if you are taking the Shinkansen (bullet train). In 2026, Japan's IC cards like Suica, Pasmo, and Icoca are almost entirely interchangeable for local subways, buses, and JR lines within a single region. However, you generally cannot "tap in" in Tokyo and "tap out" in Osaka because they belong to different regional networks. For the Shinkansen, you must purchase a separate ticket or link your Suica to the SmartEX app to use your phone as a digital ticket. Once you arrive in Osaka, your Suica will work perfectly fine on the Osaka Loop Line, the Midosuji subway line, and even at local convenience stores. It is a peer-to-peer tip to keep your Suica topped up; even though it won't pay for the bullet train directly, it is the most convenient way to navigate the local transit in both major hubs.
