Frequently Asked Questions
Answers to the questions travellers ask us most before a Japan trip.
What is the best eSIM for Japan 2026?
The best eSIM for Japan in 2026 is one you install at home that works in the city, on the train and in the mountains. For a trip of a week or two, the Japan 5GB, 15 Days plan at $14.70 covers most people. Choose the Japan 10GB plan at $29.43 if you stream, hotspot or video call every day.
How much data do I need for two weeks in Japan?
For two weeks in Japan, 5GB covers maps, translation, messaging and photos if you also use hotel WiFi. The Japan 5GB, 15 Days plan costs $14.70 Choose the 10GB plan if you share data with a partner, hotspot to a laptop or upload a lot of video.
Japan eSIM vs roaming: which is cheaper?
A Japan eSIM is usually cheaper than roaming, but check your own plan. Japan is outside EU and UK roaming bundles, and many UK, US and Canadian networks charge a daily fee or sell a travel pass for it. Multiply your network's daily fee by the days of your trip and compare it with a GleeSim Japan plan, which starts at $14.70 and is paid once. Rates change, so check your own network.
What is the cheapest phone data in Japan for tourists?
For most tourists the cheapest phone data in Japan is a data eSIM installed at home before you fly. An airport SIM counter or a rental router means a queue after a long flight, and hotel WiFi is often slow or limited to rooms. An eSIM gives you your own connection wherever there is a mobile signal.
Does one eSIM cover Tokyo, Kyoto and Osaka?
Yes. The GleeSim Japan eSIM works across Japan, so one eSIM covers Tokyo, Kyoto, Osaka, Hokkaido and every stop in between. You do not need to buy a new plan when you take the train to the next city.
Does the eSIM work when I land at Narita, Haneda or Kansai Airport?
Yes. Install the eSIM at home before you fly, then choose GleeSim as your mobile data line and turn on Data Roaming after you land. It connects to a local network, so you can message your hotel or check your train route while you queue at immigration.
Which networks does the Japan eSIM use?
GleeSim connects you to Japan's local partner networks, including NTT Docomo, SoftBank and au. Your phone joins the strongest signal available in each place. Coverage is strongest in the big cities and weaker in the mountains and remote areas.
Is there an unlimited eSIM for Japan?
Not at the moment. GleeSim does not list an unlimited plan for Japan. The biggest plan is the Japan 10GB, 15 Days plan at $29.43 If you need more data, message us on WhatsApp.
Does the eSIM work on the Shinkansen and city trains?
Signal is usually good in stations and along the main rail lines, but it can drop in tunnels and on remote stretches. Download maps, tickets and anything you need offline before you board.
Do Google Maps and Google Translate work in Japan?
Yes. Google Maps, Google Translate and messaging apps all work on mobile data in Japan. Download offline maps and the Japanese language pack before you fly as a backup for tunnels and remote areas.
Is there signal in Hokkaido and the ski resorts?
Signal is usually good in towns such as Sapporo and in the main resort villages, but it can be patchy on the slopes, mountain roads and remote areas. Download offline maps and lift information before you go.
Can I get a Japan eSIM for cherry blossom or autumn leaves season?
Yes. Order a few days before you fly, install it at home, and switch it on when you land. Spring and autumn are busy travel seasons, so order early if you are travelling with family and need several QR codes.
Does the eSIM work on Okinawa and remote islands?
If your trip includes Okinawa or other remote islands, message us on WhatsApp before you travel and we will confirm what is covered. The big cities and the main routes between them are the focus of the Japan plans.
Will my phone work with a Japan eSIM?
Your phone must support eSIM and be unlocked. Recent iPhones, Google Pixels and Samsung phones support eSIM, and you can check your model in your phone's settings or ask us on WhatsApp.
Does this plan include a Japanese phone number?
No. The GleeSim Japan eSIM is data only and does not include a +81 number for normal calls or SMS. Your home number stays active on your main SIM, and you can call your hotel over WhatsApp.
What happens if I run out of data in Japan?
Send us a WhatsApp message and we add more data to the same eSIM within minutes. You don't need a new QR code or a shop.
