Mobile data can help with train times, map directions, translation, hotel check-in details and ride bookings while travelling around Japan.

If the trip continues beyond Japan, compare the Asia 5G eSIM 13 Countries, Asia Pacific 5G eSIM 27 Countries or Asia 5G eSIM Unlimited 13 Countries. Wider itineraries may suit the Orange Global Explorer eSIM, Orange Global Explorer eSIM 180+ Countries or World Explorer 5G eSIM. Each has different coverage and activation rules. You can also browse the Asia eSIM range.

How to install and activate your Japan eSIM

Use stable internet and follow the order instructions to add the supplied QR code or redemption-generated eSIM.

  1. Check the activation rule before installation. The Japan Travel KDDI, Japan Unlimited KDDI and Japan 5G plans start on first connection to a supported network. Some regional and global plans start when installed.
  2. Add the eSIM and label it “Japan” in your mobile settings.
  3. Select it for mobile data and enable data roaming if instructed.

Do not delete the eSIM after installation unless the product instructions tell you to do so. Some eSIMs cannot be reinstalled or transferred to another device.

Networks, data speeds and hotspot use in Japan

The Japan-only plans use KDDI coverage. Regional and global products may use KDDI, NTT Docomo, Rakuten Mobile or SoftBank. Reception and speed vary with location, congestion, device compatibility and 5G availability.

Check the selected product page if tethering or sustained high-speed data is important. “Unlimited” phone data does not mean unlimited hotspot data, and some fixed-data plans continue only at reduced speed after their high-speed allowance is used.

Check your phone before buying

Your device must be eSIM-compatible and not locked to a mobile carrier. Dial *#06# and look for an EID, then confirm the exact model and regional variant with the manufacturer. The phone should not be jailbroken or rooted.

See the TravelKon eSIM setup guide for device-specific steps. If your phone does not support eSIM, compare the Japan physical SIM card range.

Need help installing or connecting? Follow the eSIM setup guide or troubleshooting guides, or contact TravelKon through WhatsApp or Facebook Messenger.

The data-usage checker is available for supported plans only. Check the selected product page for any other usage-check method.
