If you no longer need your PASMO, it can be refunded. It is also possible to refund the Commuter Pass cost on its own and switch to a Personalized PASMO card. The card must be returned. Stored fare balances cannot be refunded on their own.

Yes, standard physical PASMO cards can be refunded, but the process depends on the type of card you have. If you have a standard rechargeable PASMO, you can return it to a ticket office at any participating non-JR station (such as Tokyo Metro or Keikyu) to receive your ¥500 deposit and any remaining balance, though a small handling fee of ¥220 is typically deducted from the balance (if the balance is less than ¥220, you just get the deposit back). However, the PASMO Passport—the special version designed for tourists—is non-refundable. Any leftover funds on a PASMO Passport are forfeited once the 28-day validity period expires, so it is vital to spend the balance at convenience stores or vending machines before leaving Japan. Digital PASMO cards on Apple Wallet or Google Pay also cannot be "refunded" in the traditional sense; the funds remain in the cloud until used.
