More about the Japan eSIM
eSIM for Japan: Internet without roaming
With an eSIM for Japan, you land in Tokyo with mobile data working from minute one, without having to search for a store or struggle with SIM vending machines at Narita or Haneda airport. Our plans connect to the country's main networks (NTT Docomo and SoftBank, as well as coverage from au/KDDI and Rakuten Mobile), which offer real 4G and 5G virtually throughout the archipelago. You install the profile via QR before leaving home and activate it upon arrival. No need to change your physical card, no new numbers, and no surprises on your bill.
Roaming in Japan: why an eSIM is a good idea
Japan is not part of the European Union, so the "roam like at home" tariff does not apply. Using your operator's roaming here usually costs between €10 and €15 per day, or is even charged per MB at extremely high prices. On a two-week trip, that's hundreds of euros wasted. A data eSIM eliminates that risk: you pay a fixed rate and know exactly how much you're spending. No need to nervously monitor your usage or disable data every time you leave the hotel.
How much does an eSIM for Japan cost?
Plans start from €3.95, and you choose the GB based on your travel days. As a guide: for normal use (maps, messaging, social media, and some browsing), estimate around 1 GB for every 2 or 3 days. For a short getaway to Tokyo and Kyoto, 3 GB is usually enough; for two or three weeks touring the country, between 5 and 10 GB. If you use Google Maps a lot on the subway or share your connection, go up a level. You can see all options and other destinations in all destinations.
eSIM or SIM card in Japan
A traditional SIM card forces you to find a point of sale, take out your own and keep it safe, and many Japanese tourist SIMs are data-only anyway. An eSIM is a digital profile: it installs in seconds, doesn't occupy the slot (so you keep your usual number for SMS and calls from home) and it's ready before you take off. Less plastic, fewer hassles and no queues when you land.
Does the eSIM work in Tokyo, Osaka and Kyoto?
Yes. Coverage on Docomo and SoftBank is excellent in major cities (Tokyo, Osaka, Kyoto, Yokohama, Nagoya, Sapporo, Fukuoka and Hiroshima) and also on the Shinkansen bullet train, in Nara, Hakone or Mount Fuji. You only need an eSIM-compatible and unlocked mobile phone. You'll have internet on the subway, in temples and right in Shibuya to translate, get around and share your trip instantly.
How do I activate the Japan eSIM?
It's very simple. After purchase, you will receive a QR code via email with instructions. You scan it from your phone's settings to install the profile, and upon arriving in Japan, you activate data roaming for that line. In a few seconds, you're connected. If it's your first time, follow our step-by-step eSIM guide and you'll have it sorted before you pack your bags.
