Yes, you can purchase a Suica card at Shinjuku Station, but the process has changed recently due to global semiconductor shortages. As of 2026, sales of "regular" (unregistered) Suica cards are often suspended or restricted. However, visitors can typically still purchase the Welcome Suica (a red-themed card designed for tourists) at major transit hubs like Shinjuku. These are available at the JR East Travel Service Center (located near the New South Gate or the East Gate) or at specifically marked "Welcome Suica" vending machines. Unlike the regular Suica, the Welcome Suica is valid for only 28 days and does not require a deposit, but any remaining balance cannot be refunded. If you are looking for a standard Suica, you may be directed to use a digital version on your iPhone or Android device via the Apple Wallet or Google Pay apps, which is the most convenient method and avoids physical card shortages. If you must have a physical card, check the service windows early in the day, as daily supplies for physical tourist cards can sometimes be limited at high-traffic stations like Shinjuku.
