Yes, absolutely! We highly recommend installing your EastESIM before you even depart. You can scan the QR code and complete the setup from the comfort of your home or during your flight. Your plan's validity period with EastESIM only begins the moment it connects to a local network like NTT Docomo or SoftBank once you arrive in Japan. This ensures you have immediate internet access the second you touch down at Narita or Haneda Airport, ready to navigate Tokyo's vibrant streets.
