It seems like the whole world is talking about Japan right about now, and it’s no surprise really!
A country full of epic attractions, from Mount Fiji to Tokyo.
But when you’re visiting Japan, how do you stay connected the entire time?
Rather than relying on WiFi, you should opt for an eSIM to make sure you’ve always got an internet connection.
"Why would I always need an internet connection", I hear you ask?!
Well....Maps, opening hours, buying tickets, sharing photos, Instagram stories, Google Translate, and so much more!
So in this post I’m going to take you through my top 5 eSIMs for Japan!
But, first up…
Don’t be alarmed if you haven’t heard of an eSIM yet.
They’re still pretty new technology, but they’re absolutely everywhere now. Thank gosh!
Gone are the days of having to search for a sim card every time you land in a new country (I am seriously glad I don’t have to do this anymore). eSIMS are the future.
An eSIM is like the digital version of a regular SIM card.
Instead of using a physical SIM, eSIMs come pre-installed in your phone.
That means all your data is stored digitally.
You can activate it by purchasing and installing different eSIM plans, letting your device connect to mobile networks worldwide.
With this virtual setup, there’s no need to insert a physical card into your phone.
Unlike a mobile WiFi hotspot or portable WiFi, an eSIM allows your phone to connect directly to the internet through the local cellular provider.
No extra gadgets needed!
Taking the top spot for eSIMs for visiting Japan is, Sim Local!
Why?
Well, to start, Sim Local is partnered with AU, one of the leading mobile networks in Japan, well known for its reliability and fast speeds.
This means you can stay connected, fuss free, on your entire trip.
If you’re heading to Japan, staying connected is a must. And with Sim Local, you get a fast, reliable, and hassle-free mobile experience.
Here’s why it’s a top choice:
Sim Local only partners with the best mobile providers worldwide, and Japan is no exception. Their AU plans ensure strong, stable connections throughout your trip—so whether you’re navigating bustling Tokyo or exploring remote temples, you’ll always stay connected.
Need to share your internet with your laptop, tablet, partner or friend? No problem!
With Sim Local’s unlimited data plans (naturally they’re subject to fair usage), you can connect multiple devices seamlessly.
This makes me sooo happy, because if you’re a digital nomad like myself, or you simply travel with a laptop for planning, you NEED to be able to hotspot.
And I thoroughly hate it when eSIM plans don’t have that as an option ;)
Thankfully, you have no issues with Sim Local!
AU plans offer the best data-to-price ratio out there, making them an affordable and efficient choice for travelers.
Since they are known for their widespread coverage, fast speeds, and top-rated customer service—you pretty much know your money is well spent.
Plus, if you don’t need as much data, there are lower GB plans available to suit your specific travel needs.
Plus it’s even cheaper when you use our discount code of DREAMBIG10 for 10% off ;)
Forget the stress of running out of data! An eSIM with Sim Local will provide a reliable, unlimited data experience without unexpected speed drops or cutoffs.
Whether you’re working remotely, streaming, or using maps on the go, you’ll always have seamless connectivity—letting you focus on enjoying Japan to the fullest.
Overall, I’d say the unlimited data plans for Japan with Sim Local are actually some of the best value I’ve come across!
1. No Voice or SMS Services: Most eSIM data plans (including Sim Local) do not include calls or SMS—they’re data-only. If you need to make local calls (e.g., to hotels, restaurants, or for emergencies), you’ll need to use services like WhatsApp, Skype, or Line, which may not always be accepted by some Japanese services that require a local number.
Saily offers a range of eSIM data plans tailored for travelers to Japan, providing flexible and affordable options to stay connected.
Their competitive pricing, ease of use, and flexible data plans make it a strong contender for those looking to stay connected while exploring Japan. They also allow hotspotting, which makes it a winner in my eyes!
They also offer a Global Data plan that includes Japan.
Plan Options and Pricing: Saily's Japan eSIM plans are designed to cater to various data needs and durations:
Maya mobile is another eSIM provider that I used, who provided eSIM plans for Japan. I’ve never had any issues with Maya Mobile, and I like how easy the eSIMS are to buy and use. In terms of what they offer for Japan.
Data Packages: Choose from 3 GB, 5 GB, 10 GB, and 20 GB plans, catering to various data needs for a good price.
Unlimited Data: Daily unlimited data plans are available, providing continuous connectivity throughout your stay.
You can also hot spot data with them on Unlimited and Prepaid plans!
Eskimo is a little different.
They do offer eSIMS for specific countries, like Japan, but in addition to that they offer one global eSIM that covers 80 countries for 2 years.
This is a great option if you’re planning on visiting Japan multiple times, or you’re planning on visiting travelling to a bunch of different places.
Holafly are a popular eSIM provider and they offer Japan options too- mainly in the form of Unlimited data.
Which is great, BUT they have restrictions on the amount of data you can hot spot (500MB), which makes it a little difficult for me to choose. BUT, if I’m just using my phone, then it’s not a bad shout.
Plan Options and Pricing: Holafly's Japan eSIM plans come with unlimited data and are available for various durations:

One of the biggest advantages of an eSIM is its flexibility.
Forget the struggle of buying and inserting a physical SIM card every time you land in a new country.
Physical SIM cards and international roaming can be costly, but eSIMs offer a more affordable alternative:
Say goodbye to misplacing tiny SIM cards or struggling with different SIM sizes. I am so guilty of losing sim cards, btw, so this is one of the main reasons I love eSIMS for travel.
Even with dual SIM phones, swapping SIMs constantly can be a hassle.
So there you have it!
