When you purchase the Suica & N'EX package, you will receive a Suica card plus a Narita Express ticket. Use the NEX ticket for your ride into Tokyo or Yokohama. Thereafter, you can use the Suica card on the JR and other trains in and around Tokyo and elsewhere in Japan.

You can use a Suica card (or other IC cards like PASMO) to pay the base fare for the JR Narita Express (N'EX), but you cannot use it as your only ticket. The Narita Express is a "Limited Express" train, which means it requires both a base fare and a Limited Express reserved seat ticket. To use your Suica, you would tap in at the gate to cover the base fare, but you must separately purchase a seat reservation at a ticket machine or via the JR East website. If you only tap your Suica and board the train, you will be required to pay the supplemental fee to the conductor, often at a higher "onboard" rate. In 2026, the Mobile Suica and Welcome Suica apps have made this easier by allowing you to link a digital reserved ticket directly to your phone's IC card. This allows you to tap through the gates and sit in your assigned seat without a paper slip. Remember that the N'EX is all-reserved; there are no unreserved cars, so having a seat assignment is mandatory before boarding.
