Updated April 22, 2026

Yes, an active data connection is critically important. To access Super Nintendo World at Universal Studios Japan (USJ), you must utilize the official USJ App on your mobile device. This application requires live internet connectivity to secure your "Timed Entry e-Ticket" or "Standby Entry Ticket," which are mandatory for entry into the themed zone. CoreESIM ensures you have the necessary data throughput for this essential park operation.
