We’ll email your setup details when your eSIM is ready. Save the email for your arrival.
Wait until you have landed before using Quick Install, scanning the QR code, entering the manual code or activating the eSIM.
Join the airport’s passenger Wi-Fi and complete its sign-in screen. Open a webpage to check you’re connected.
Then open your SIM Shop setup email and follow the instructions to install and activate your eSIM.

Check that your phone supports eSIM and is network unlocked before buying.
A Tokyo to Kyoto to Osaka itinerary needs data for station exits, hotel addresses, translation and reservations as well as sightseeing. Save your first transfer and accommodation details on Wi-Fi before heading out. Rail tunnels, underground stations and remote stretches can interrupt reception even when Japan is included.
Messages and calls in apps use your data. Standard calls, SMS and a local number need a separate mobile service.
Choose your trip length, then compare the available unlimited plans. Check the selected plan’s speed, hotspot allowance, any reduced-speed terms and start window.
Buy Japan eSIM data before you travel. Pick the data amount that fits your trip and save the setup email, but do not tap quick install, scan the QR code, enter the manual code or activate the eSIM before departure.

Heading to Hokkaido for a drive or Okinawa for an island stay? Check the chosen plan’s supported network for your actual accommodation and route. Download the maps you will need away from larger towns. A 5G-capable plan and phone do not guarantee 5G at every stop.
For Tokyo plus Seoul, compare the exact country list and total allowance on a Japan and South Korea plan with two separate country plans. A shared regional allowance does not restart when you cross the border. Choose based on your dates and data budget, not simply the number of destinations on the label.
Daily high-speed options are day passes with a set high-speed amount each day. After that daily amount is used, speeds may reduce until the next daily reset.
These plans are data-only unless a product option says otherwise. They do not include a local phone number for standard calls or SMS. Check compatibility, coverage, validity and hotspot needs before purchase.
Recommended setup timing: buy before you fly, then install only after you land. Join the airport’s free passenger Wi-Fi where offered, complete its sign-in page and open a normal webpage to prove it works. If it is unavailable or unstable, wait for hotel Wi-Fi or another steady trusted connection. Open your SIM Shop setup email and install only when that Wi-Fi test works.
Train changes, translation, maps and bookings all use data. Start with the length of your Japan trip, then compare the speed and hotspot terms above.
Japan has a capped 10Mbps range and a full-speed range with no plan-level speed cap. Actual speeds depend on the local network, your phone, location and congestion.
Hotspot terms depend on your selected plan. Local KDDI unlimited plans have a separate hotspot allowance across the whole trip, shown with each duration. Other full-speed and capped-speed options have their own hotspot terms. Check your selected plan before buying.
Day passes have a stated high-speed allowance each day, with their own reset and reduced-speed terms. You’ll find those alongside fixed data on the regular Japan eSIM page.
Choose a plan long enough for your trip, check its start window and use Phone Check to confirm eSIM support. Save your setup email before leaving. Land, join airport Wi-Fi, then follow the setup email. If airport Wi-Fi is unavailable, use hotel Wi-Fi or another steady trusted connection.
