Can we just swipe the same card 3 times while going thru the gate? You need 3 cards. Every individual needs their own cards to use train. Scanning the card three times to allow three people, or giving the card back so three people could use it would not work because of the design of the system.

In 2026, the short answer is yes, every traveler needs their own individual Suica card (or equivalent IC card like Pasmo or Icoca) to use Japan's public transit system. Because the system calculates fares based on the specific entry and exit points of each person, you cannot "tap" one card multiple times to pay for a group at a single turnstile. Each card must maintain its own independent balance and track a unique journey. For families traveling in 2026, children under six usually travel for free, but children aged 6 to 11 require a dedicated "Child Suica" which automatically deducts the discounted child fare. Most travelers now opt for the mobile Suica integrated into Apple Wallet or Google Pay, which allows for instant top-ups via credit card, bypassing the need to find physical ticket machines that have become less common in 2026. If you are traveling in a group, ensure each member has their own digital or physical card ready before approaching the gates to avoid blocking the flow of commuters.
