Japan is not a country where you want to be offline. Train platforms look identical in kanji, rural buses run on paper schedules, and the IC-card tap-to-pay system assumes you've got a working data connection for the balance-refill apps. A Blikst Japan eSIM runs on KDDI's au network — the same infrastructure most international roaming SIMs use — with full LTE across Honshu, Kyushu, Shikoku, and Hokkaido, and 5G in Tokyo, Osaka, Kyoto, Nagoya, Sapporo, Fukuoka, and along the Shinkansen corridor.
Tokyo, Osaka, Kyoto, and the Tōkaidō Shinkansen line between them have blanket 5G. Rural Hokkaido north of Asahikawa, the interior of Kyushu's volcanic regions (Kirishima, Aso), and the Iya Valley on Shikoku fall back to 4G — still usable for maps and messaging. Underground in Tokyo Metro and Osaka Metro, signal drops between stations but recovers at every platform. The Tokyo–Osaka Shinkansen has working data almost the entire route except for tunnels.
Japan's traditional traveller option is a rental pocket Wi-Fi router, which runs about ¥800–¥1,200 per day (£4–£7) and has to be picked up and returned. A Blikst 30-day 10 GB plan costs less than five days of a pocket Wi-Fi rental, doesn't require queuing at the airport counter, and doesn't give you a second device to charge or lose. Unlimited plans include 3 GB per day at high speed (same as most pocket Wi-Fi contracts), then continue at 256 Kbps — enough for messaging and maps, not enough for video.
Unlimited plans on this KDDI line need IMEI and EID numbers plus your activation date — provide those at checkout at least 2 days before you land. The plan activates automatically on your chosen date. Limited-GB plans (1 GB to 100 GB) use the standard QR-code scan and activate on first use in Japan. Install the profile on your phone before you fly; airport Wi-Fi at Narita and Haneda is free but crowded, and you do not want to be debugging an eSIM install in a jet-lag fog.
One-week Tokyo-only trip: 3–5 GB is plenty. Two-week Tokyo–Kyoto–Osaka classic route: 10 GB. Three-week Japan-rail-pass grand tour with multiple cities and regional lines: 20 GB or the unlimited plan. Remote-work visitors staying a month should go unlimited; the 3 GB/day soft cap is the pocket-Wi-Fi default and is hard to exceed without heavy streaming.
Land at Narita, Haneda, Kansai, or New Chitose with your Blikst eSIM already active. Skip the pocket Wi-Fi counter, skip the international roaming bill, and spend the time looking up where the good ramen is instead.

An eSIM, or Embedded SIM, is a digital SIM that allows you to activate a mobile plan without using a physical SIM card. It is built directly into your smartphone, smartwatch, or tablet and provides the same functionality as a physical SIM. With eSIM, switching between carriers or adding a secondary number becomes seamless and hassle-free.
Getting an eSIM for Japan is simple! Check if your device supports eSIM technology. Then, purchase an eSIM plan from your preferred carrier or from our website. After purchase, you’ll receive a QR code or activation details to set up the eSIM on your device in minutes.
Most modern smartphones, including the latest iPhones, Samsung Galaxy models, and Google Pixel devices, are eSIM compatible. Check your device settings under “Cellular” or “Mobile Data” to see if eSIM options are available. Alternatively, refer to your device’s specifications or contact us for guidance.
The number of eSIMs you can have depends on your device. For example, most iPhones allow multiple eSIM profiles but only one active eSIM at a time. Some Android devices support dual-active eSIMs, giving you more flexibility. Check your device’s specifications for details.
Activating an eSIM involves a few easy steps: 1. Purchase an eSIM plan from our website or your carrier. 2. Scan the provided QR code using your device’s camera or enter the activation code manually. 3. Follow the on-screen instructions to add the eSIM profile to your device. Once activated, your eSIM is ready to use!
To activate an eSIM on iPhone: 1. Go to Settings > Cellular > Add Cellular Plan. 2. Scan the QR code from your eSIM provider or enter the activation details manually. 3. Choose your preferred settings for data, calls, and messaging, then tap Done. Your eSIM is now set up and ready to use.
Yes, eSIM offers several advantages over traditional SIM cards: Convenience: No physical SIM card required. Flexibility: Easily switch between carriers or plans. Space-saving: Frees up internal space in devices for additional features. Eco-friendly: Reduces plastic waste. Upgrade to eSIM and experience seamless connectivity like never before.
Unfortunately, it is not possible to transfer your Japan eSIM using the same QR code, as QR codes can only be scanned once for security reasons. If you wish to use your eSIM on a new device, you will need to contact your carrier to request a new activation code or QR code. Once issued, you can set up the eSIM on your new device following the standard activation process.
