No, two people cannot share a single Suica card for the same journey on Japanese trains or buses. This is because the Suica system operates on a "tap-in, tap-out" logic to calculate your fare based on the distance traveled. When you tap into a station, the card is marked as "in transit." If you were to pass the card back to a second person, the gate would show an error because the card is already active in the system. Each traveler must have their own individual Suica card (or Pasmo/Icoca card) to pass through the ticket gates. In 2026, the most convenient "pro" solution is for each person to have a digital Suica on their own smartphone. This allows each person to "tap" their phone independently at the gate. If you are traveling with a child under 6, they usually travel for free and do not need a card, but for anyone 6 and older, an individual card is required. You can, however, use a single Suica card to pay for items at a convenience store for multiple people, as that is a simple retail transaction without a "tap-out" requirement.
