    KDDI au & SoftBank Coverage for the Whole Month

    Your eSIM rides Japan's leading networks with 4G/5G in Tokyo, Osaka, Kyoto, Sapporo and Fukuoka, and dependable data on Shinkansen routes between them - the same coverage whether it's day 1 or day 30.

    The 30 Days Start When You Activate, Not When You Buy

    Order any time before your trip. Install the eSIM at home over Wi-Fi, keep the line off, and your validity only begins once it connects to a Japanese network after you land at NRT, HND or KIX.

    Staying Past a Month? Top Up, Don't Reinstall

    Add data from your BitJoy account before expiry and the same eSIM keeps going with extended validity. For very long stays, a Japan 50GB 180-day plan is available on the main Japan page.

      It activated quickly. I connected without any issues after receiving the QR code in a matter of minutes. The ability to pay with cryptocurrencies was also appreciated; the entire process went well. I had no trouble staying connected during my journey because of it. For hassle-free internet access, BitJoy is a great option if you're planning a trip soon!

      The activation process is not complicated, and it was done quickly by following the steps. The payment method is also flexible. I tried credit card and cryptocurrency payment, and both were completed smoothly, and the payment was immediate. When I arrived at the local area, I scanned the code to connect to the Internet, which is very convenient and very suitable for travel.

      I'm giving 4 stars because the installation guide didn't mention that I had to set up the APN manually, and support also didn't immediately suggest it. I had to do some troubleshooting myself. Other than that, so far so good. P.S. I used it in Turkey and the APN is 'isp.'

      I purchased data from BitJoy for my father. Data worked as promised by the team. My father didn't face any problem at Toronto airport.

    • It starts at activation, not at purchase. Install the eSIM at home over WiFi and keep the line switched off; the 30 days only begin once the eSIM connects to a network in Japan. Buying a week before your flight costs you nothing in validity.
