Absolutely, that's one of the prime benefits of using an EastESIM for your trip to Japan! We highly recommend installing and activating your eSIM while you still have a stable internet connection at home or at your departure airport. You'll receive a QR code, which you scan to install the digital SIM profile. The eSIM will then lie dormant until you arrive in Japan and it detects a local network like Docomo or SoftBank, at which point it automatically connects. This ensures you're online the moment you step off the plane in Narita or Kansai.
