Japan is a technologically advanced country that has widely adopted eSIM technology. All major Japanese carriers including NTT DoCoMo, SoftBank, and KDDI offer eSIM plans. So getting an eSIM in Japan is easy and convenient for travelers.
In this article, I'll provide an overview of eSIM Japan and explain everything you need to know about availability, compatibility, carriers, plans, and more. Let's get started!
What is eSIM?
An eSIM or embedded SIM is a virtual SIM card embedded into your phone or device. Unlike traditional physical nano-SIM cards, eSIMs don't require a SIM tray.
eSIM Japan works the same as a regular SIM card. The only difference is eSIM comes as a QR code you can scan to activate mobile service.
Key benefits of eSIM technology include:
- No need to find and purchase SIM cards when traveling.
- Ability to quickly switch between plans and carriers.
- Remote provisioning without visiting stores.
- Dual standby mode on select devices.
These make eSIM super convenient for managing connectivity in Japan.
eSIM Compatibility in Japan
In 2024, most new iPhone, Samsung, Huawei, Google Pixel, and other flagship devices support eSIM globally including Japan.
However, there are still many phones without embedded SIM capability. So before getting Japan eSIM, check your phone's specifications to confirm compatibility.
I recommend the iPhone 14 series or Samsung Galaxy S23 lineup to enjoy full dual eSIM functionality for Japan. But many older models also work fine.
Availability of eSIM in Japan
The top three carriers in Japan - NTT DoCoMo, SoftBank, and KDDI AU - have offered eSIM plans for a few years now.
You can easily find and purchase Japan eSIM plans from them or third-party resellers before your trip. Prices start around 3,000 JPY ($25 USD) for a 7-day prepaid tourist eSIM with 10GB LTE data.
But as a foreign traveler, I don't recommend getting eSIM service directly from Japanese carriers. Their account creation process can be complicated requiring Japanese credit cards or residency documents.
Getting eSIM for Japan from Asian eSIM
That's why I highly recommend getting Japan eSIM service from Asian eSIM. They make the entire process quick and hassle-free for travelers.
Asian eSIM offers prepaid Japan eSIM plans at affordable rates. You can choose data packages ranging from 1GB for 3 days to 20GB for 30 days.
After purchase, you instantly receive the eSIM voucher QR code and activation instructions via email. There is no account registration or verification required.
Once you scan the QR code, mobile data starts in a few minutes without visiting any stores. This enables internet access right upon arrival at a Japanese airport.
So rather than worrying about Japan SIM cards, go for eSIM from Asian eSIM for the ultimate connectivity abroad!
How to Use eSIM in Japan
If you aren't familiar with eSIM already, here is a quick tutorial on How to use eSIM in Japan:
-
Install the eSIM app provided by your device manufacturer e.g. iPhone's Cellular Data or Samsung eSIM Manager. This app allows managing digital SIM profiles.
-
Launch the eSIM app then tap Add Cellular Plan or the + icon.
-
Select Scan QR code and point your phone camera at the QR code from your Japan eSIM voucher.
-
Follow the on-screen activation process and wait several minutes for mobile data to start.
That's all there is to it! You can now use the high-speed data for calls, messaging, maps, social media, and any other internet needs in Japan.
The process is quite straightforward but reach out if you need any assistance with managing multiple SIMs or troubleshooting your eSIM Japan.
Now that you know eSIM availability and activation in Japan, the last thing is choosing the right service plan.
How to Select Japan eSIM Plan
With so many prepaid data options from various Japan eSIM providers, it can get confusing picking the best plan.
I recommend framing your decision based on data volume and trip duration needs:
- Short 1-7 day trip: Get a 7-day eSIM plan with at least 10GB
- Medium 8-15 day trip: Go for 15-day plan with 15GB+ data
- Long 16-30 day trip: Pick a monthly plan up to 20GB data
If you plan on using mobile data mostly for essential needs like maps, messaging or light web browsing, even a basic 1GB eSIM will do.
But for photography, video streaming, gaming, remote work and other data-hungry use cases - maximize the high-speed allotment.
Fortunately, Asian eSIM Japan plans scale from 1GB all the way to unlimited data. You can conveniently purchase more data as needed anytime.
