Best eSIM for Japan


For Japan, Saily is the cheapest eSIM if you count your data (1 GB for 7 days at $3.99 USD), and Holafly is the most flexible for unlimited data, down to the exact day ($38.00 CAD for 7 days). Airalo sits in between, with fixed and unlimited plans billed in Canadian dollars.
Taking a trip to Japan is something that many people dream of doing. With many diverse regions showcasing incredible food, natural beauty, and millennia of cultural history, Japan is a compelling destination for any traveller.
Of course, once you're in Japan, you'll want to make the most of your time there, and you'll also likely want to stay connected with loved ones back home to share your adventure. With a good eSIM, you'll be able to connect to data in most of Japan using your device to translate restaurant menus, navigate public transit, send pictures back home, and more.
In our article below, we share the best eSIMs for Japan so you can feel confident, comfortable, and connected as you explore this spectacular country.

An eSIM is an entirely digital SIM card that works with pre-installed software on your compatible device. Using this technology, you can download and set up a travel eSIM before you even take off, then arrive at your destination ready to connect to a local network.
In the past, mobile devices used to exclusively have physical SIM cards that would have to be manually put in and taken out when you wanted to connect to a new network abroad. These physical SIM cards (which are still available and used in most devices) were usually purchased from a kiosk at the airport when you arrived, making it one of the first things you would have to do when you landed.
Now, thanks to eSIMs, the process of staying connected while travelling is much easier. Most new smart devices, such as smartphones, tablets, and smartwatches, are compatible with eSIMs, and as long as your device is compatible, an eSIM can be installed in a few quick steps using a QR code.
Once connected when you arrive at your destination, you should have near-instant access to data networks in countries like Japan and across the globe.
There's a number of reasons to choose to get an eSIM for your trip to Japan (or just about anywhere else in the world). These include:
Japan is a pretty big country spread across over 14,000 islands (though only a few hundred of these are inhabited), and most travellers would love to stay connected regardless of where in the country they visit.
Whether you’re exploring the differences between Tokyo's many districts, travelling to Okinawa for its incredibly unique food and culture, frolicking in the snow in Sapporo, or standing in awe of the temples in Kyoto, staying connected with an eSIM will help make your trip better.
For travel to Japan, there are three major eSIM vendors that we recommend for Canadians: Saily, Airalo, and Holafly. All three offer similar network coverage through Japan's major networks, including SoftBank and KDDI, so you'll mostly be comparing price and data quantities when selecting the best option for your trip.
When you're choosing the best eSIM for Japan, there are a few key things that you'll want to consider:
When it comes to choosing a great eSIM for Japan, we're starting our recommendations with the array of options from Saily.
We recommend Saily's eSIMs because not only are they easy to download and install, but the company also has excellent customer service. Their team is on stand-by 24/7 in case you need some extra help with the installation process or with your eSIM once you're already on the road.
For Japan-specific travel, Saily offers the following eSIM data plans:
| Data | Period of Validity | Price |
|---|---|---|
| 1 GB | 7 days | $3.99 USD |
| 3 GB | 30 days | $7.99 USD |
| 5 GB | 30 days | $10.99 USD |
| 10 GB | 30 days | $17.99 USD |
| 20 GB | 30 days | $24.99 USD |
| Unlimited data | 5–30 days | $18.99–71.99 USD |
Plus conveniently, your Saily eSIM comes with a 180-day activation window, so you can get it set well before you travel to get one thing checked off your to-do list. Just note that if you don't activate your eSIM within 180 days, it will be activated automatically.
Saily customers can also enjoy 3% back in bonus credits each time they purchase an eSIM, and every time they successfully refer a friend, they get $5 USD in credit. These accumulated credits can then be used to help pay for your next Saily eSIM.
Additionally, Saily stands out from its competitors by allowing you to use a single eSIM for every destination you visit. Whereas most other eSIM vendors require that you download and install a new eSIM for each new destination/region, Saily lets you piggyback on the one you've already got. As long as you don't delete your Saily eSIM, the data plans for your future destinations should just be seamlessly added after your purchase.
Keep in mind that eSIMs purchased through Saily are charged in US dollars. Given this, it can be a good idea to make the purchase with a credit card that doesn't charge foreign transaction (FX) fees. A card like the Scotiabank Passport Visa Infinite+ Card will not only save you the 2.5% foreign currency fee on your Saily eSIM purchase, but it'll also extend these savings to all purchases made abroad.
Saily's parent company is Nord Security which also runs NordVPN, one of the best VPN services in the world. Once you've got your eSIM planned out, you may find that it's worth also exploring a VPN for your upcoming trip to help keep your data safe around the world.
The second eSIM vendor that we recommend to keep you connected in Japan is Airalo.
Airalo's eSIM packages for Japan range as follows:
| Data | Period of Validity | Price |
|---|---|---|
| 1–3 GB | 3 days | $6.00–11.00 CAD |
| 3–10 GB | 7 days | $11.50–24.50 CAD |
| 5–20 GB | 15 days | $15.00–34.50 CAD |
| 5–20 GB | 30 days | $16.00–35.50 CAD |
| Unlimited | 3–30 days | $16.50–98.00 CAD |
As you can see from the table above, Airalo offers a range of data quantities for select time frames, up to 30 days in length.
Similarly to Saily, Airalo also incentivizes your loyalty using a rewards system. With Airalo, every time you purchase an eSIM or refer a friend, you will earn Airmoney. Your accumulated Airmoney can then be redeemed toward the cost of your next eSIM purchase.
Notably, for some destinations Airalo offers the option to choose an eSIM package that includes calling and texting capabilities in addition to data. However, this option is not available in Japan, so travellers are limited to data-based texting and messaging apps like WhatsApp and FaceTime.
Our third recommended eSIM vendor is a great choice if you plan to use a lot of data while you're travelling in Japan. This is because every one of Holafly’s eSIM plans comes with unlimited data.
Additionally, Holafly lets you choose the exact number of days for your eSIM plan, meaning that you never have to pay for something you're not using. Plus, if that wasn't enough, Holafly has also introduced the Always On feature which gives you 1 GB of free "backup data" every month after your purchased plan ends.
The Always On data becomes available after you've installed your Holafly eSIM, and it remains accessible as long as you don't delete/uninstall it. The 1 GB automatically refreshes every 30 days, so you'll always have access to data in hundreds of destinations around the world.
Holafly also lets you share your data via your device's hotspot function up to a maximum of 1 GB per day. Additionally, if you ever need help with your eSIM, Holafly offers 24/7 customer support to make sure you stay connected.
Through Holafly, an eSIM plan for Japan can be selected for 1 to 90 days, with the cost per day becoming significantly lower the longer you stay. To give you an idea of the price for a Holafly eSIM in Japan, here are some common trip lengths with prices and the cost per day breakdown (all figures in CAD):
Regardless of where in the country your trip to Japan takes you, having a reliable eSIM is a great way to stay connected and make your travels more pleasant. Thanks to online eSIM vendors like Saily, Airalo and Holafly, it's incredibly easy to find the right plan for your trip length and data needs.

eSIMs absolutely work in Japan. The country has strong nationwide coverage through the same networks used by eSIMs, such as SoftBank and KDDI. However, keep in mind that while coverage is quite reliable in cities, along the train corridors, and in most tourist areas, it may become inconsistent or unavailable in remote mountain or island regions.
For 15 days of unlimited data, expect to pay $68.50 CAD with Airalo and $70.00 CAD with Holafly. Saily lists its plan at $48.99 USD, charged in US dollars: you get full speed up to 5 GB per day, then the connection drops to 1 Mbps.
To use an eSIM on your next trip, simply follow these steps:
Absolutely. eSIMs that are purchased through reputable vendors like Saily, Airalo, and Holafly are both trustworthy and reliable.
Not with these plans: the Japan eSIMs from Saily, Airalo, and Holafly are data-only and don't come with a local phone number. To send/receive texts or make a voice call, you will need to use a data-based service like WhatsApp, FaceTime, or another similar app.
It's best to install your eSIM at home before your trip as you need to have a strong Wi-Fi connection. Plus, by having your eSIM ready to go before your trip, it means that you can step off the plane and immediately connect to the local network – very convenient for navigating a new destination.
