Regular IC cards, including Suica, Pasmo and Icoca, can be used on non-reserved seats of shinkansen trains in the entire service area of JR East (see map above). Before you can use an IC card for this service, which is known as Touch de Go, a one-time set-up procedure is required at a ticket machine.

In 2026, you cannot simply "tap and go" with a standard Suica card to board the Shinkansen unless you have specifically registered for the "Touch de Go! Shinkansen" service. Standard Suica, Pasmo, or Icoca cards are for local commuter trains and do not cover the "Limited Express" surcharges required for high-speed rail. However, through the SmartEX app or the JR East "Touch de Go" registration at station kiosks, you can link your Suica card (including the digital version in your Apple/Google Wallet) to a specific Shinkansen ticket you've purchased online. Once linked, you can indeed tap your phone or card at the Shinkansen gates. In 2026, this is the preferred method for many travelers as it eliminates the need for physical paper tickets. Note that for the Nozomi and Mizuho trains on the Tokaido line, you must use the SmartEX system, while "Touch de Go" is primarily for non-reserved seats on the Tohoku, Joetsu, and Hokuriku Shinkansen lines.
