In 2026, the primary difference between Welcome Pasmo and Welcome Suica is the issuing company and the specific "souvenir" artwork, though they function identically for the traveler. Welcome Suica is issued by JR East and is typically available at Narita and Haneda airports; it features a red design with cherry blossoms. Welcome Pasmo (formerly Pasmo Passport) is issued by a consortium of private subways and buses and is available at major Tokyo Metro stations. Both cards are "tourist-only" versions that require no deposit and are valid for exactly 28 days, after which the balance is forfeited and the card becomes a "free" souvenir. A high-value peer tip for 2026: if you have an iPhone, you should bypass the physical cards entirely and add a "Digital Suica" to your Apple Wallet for free; it has no expiration date and can be topped up instantly. If you want the physical card for a scrapbook, choose the "Suica" for JR-heavy travel or "Pasmo" for more metro-heavy travel, but both are universally accepted across almost all Japanese transit.
