Adding a Suica commuter pass to Apple Pay is just as easy as a regular Suica. You can also renew the commuter pass right in Wallet without a trip to Suica App. However one thing you need to be careful of is the commuter pass renewal window.
Suica commuter passes are good for 1-3-6 month renewable periods that you choose when renewing the pass in Wallet. You can only renew a commuter pass two weeks before the expiration date. If you go past the expiration date and miss the two-week renewal window you can no longer renew the commuter pass in Wallet.
In this case you have to use the Suica App and be signed in with your Mobile Suica ID. In Suica App purchase a “new” commuter pass. You will need to input the start and end station points, any transfer point station, the validity period and the start date. The last step is the purchase with Apple Pay. Follow the screen shots below.
Once complete your Apple Pay Suica commuter pass is ready to go. It is not a new Suica card, it is the same card with a new validity period.
