Planning a trip to Japan and wondering which eSIM won’t leave you lost in translation (or lost without Google Maps)? I’ve got you!
I spent a week exploring Japan with my husband and after traveling to 65+ countries as a full-time content creator, I’ve tested my fair share of eSIMs so you don’t have to.
If you’re anything like me, you want something effortless, unlimited, and reliable the moment you land. That’s why I’m sharing my go-to pick for Japan: an eSIM that gives you unlimited data and truly total peace of mind.
Let’s make sure your Japan adventure is fully connected! Here’s why Holafly is the best eSIM for Japan and why thousands of travelers swear by it.
Holafly Overview
Overall, I recommend the Holafly Japan eSIM because it’s the most seamless option for digital nomads and travelers who just want reliable, unlimited data without thinking twice.
All you have to do is install it before your trip when you’re connected to wifi, and then it will activate and work the moment you land!
It gives you fast coverage everywhere from Tokyo’s busiest crossings to tiny mountain towns.
No topping up, no worrying about running out of data, and no hunting down SIM cards after a long flight. It’s the kind of set-it-and-forget-it connectivity that travelers love!
What is Holafly?
Holafly is a travel eSIM provider that gives you fast, reliable mobile data in countries around the world without needing a physical SIM card.
Instead of buying a SIM at the airport or dealing with roaming fees, you simply purchase an eSIM online, scan a QR code, install it on your phone, and you’re connected as soon as you land.
Holafly Features
Unlimited Data
Unlimited data is a total game changer for staying connected in Japan, especially if you’re someone who’s constantly online for work or navigation (or posting)!
Instead of stressing over data limits or cutting back on usage, you can video call clients, upload high-resolution content, stream, and message freely without ever worrying about running out.
It gives you the freedom to stay in touch with loved ones and share your trip in real time.
Fast and Reliable Internet
Fast and reliable internet is essential for travelers in Japan because it turns every moment into a smooth, stress-free experience.
With strong coverage, you can quickly look up bus and train times, follow Waze or Google Maps without delays, and order Ubers or taxis right when you need them.
Instead of guessing, waiting, or hoping you’re on the right platform, you always have real-time information at your fingertips.
500MB Shareable Data
Being able to share up to 500MB of data with friends or family is a huge perk, especially if someone in your group doesn’t want to buy their own eSIM or you’re juggling a second device.
It means you can quickly hotspot for directions or essential messages.
It’s perfect for helping a partner book an Uber, letting a friend upload a photo, or getting your tablet online without extra setups or purchases.

Cons of Holafly Japan eSIM
No phone number included: you can’t make local calls or receive SMS.
BUT you can keep your original SIM active for calls/texts or use apps like WhatsApp or FaceTime.
Personal hotspot is limited (up to 500MB shared): not ideal if you want to tether multiple devices all day.
BUT unlimited data still covers your main device, and 500MB is enough for quick essentials on a second device.
Slightly higher price than local SIM cards: cheaper options exist if you’re willing to buy in person.
BUT Holafly saves time, avoids language barriers, and works instantly upon landing with zero setup at the airport.
Speeds can vary in very crowded areas like Shibuya Crossing during peak hours.
BUT speeds remain fast enough for navigation, messaging, and uploads throughout your trip.
Requires an eSIM-compatible phone so older devices may not work.
BUT most recent iPhones and many Android models are fully supported, and Holafly has a quick compatibility checker here.
My Experience using Holafly in Japan
From my own experience, the Holafly Japan eSIM worked perfectly from the moment I landed. As soon as I turned airplane mode off, I was instantly connected.
All you have to do is install the eSIM before your trip when you are connected to wifi, and then activate it when you land (which doesn’t require wifi as it automatically connects to the available data network in Japan).
I was able to upload videos, check emails, and even hop on FaceTime with my parents right at the airport.
The speeds stayed fast throughout my entire trip and made the transition into another country so seamless that I didn’t even have to think about my connection once.
Who is Holafly for?
Holafly’s Japan eSIM is especially perfect for the tech-savvy on-the-go digital traveler, someone who loves exploring new countries but still needs unlimited data for navigation, communication, and work.
If you value convenience, speed, and staying connected every moment of your trip from touchdown to takeoff, Holafly is for you!
Holafly Japan Pricing
Pricing for Holafly’s Japan eSIM depends on how many days you need service, which makes it flexible.
You purchase for a set number of days and you can always extend later. The days don’t start counting until the first day you activate it.
For example, a 5-day plan might cost around US $20, while a 10-day plan could be roughly US $37. If you’re staying for a full month, a 30-day plan might run you around US $75.
These are approximate figures, always check Holafly’s website for their current pricing.

Saily offers flexible data-only plans in Japan, ranging from small allowances to unlimited data depending on the plan. It also includes added security features like ad-blocking and web protection.
