Planning a trip to Japan? Let’s break down the two most popular ways to stay connected, Jetpac’s travel eSIM vs the good ol’ Pocket WiFi.
Staying connected while traveling in Japan is pretty much a must in today’s internet-driven world. You’ll need it to navigate Tokyo’s busy streets, check train schedules, and even translate restaurant menus, which, let’s be honest, is especially important if you want to eat at local restaurants.
And while you’ll find public Wi-Fi in places like hotels, train stations, and restaurants, having your own connection is key for uninterrupted access and a much more secure browsing experience.
When it comes to staying connected in Japan, the two best options out there are Pocket WiFi and eSIMs. But which one should you choose? In this guide, we’ll break down everything you need to know about Jetpac Japan eSIM and Pocket WiFi so you can pick the one guaranteed to keep your trip smooth, fun, and hassle-free.

What is a Jetpac Japan eSIM?
A Jetpac Japan eSIM is your digital ticket to staying connected while exploring the Land of the Rising Sun. With Jetpac, there will be no SIM-swapping or Wi-Fi hunting required.
Short for embedded SIM, an eSIM works just like a regular SIM card, but it’s built right into your phone. That means you can activate it instantly without any physical card or trip to a local shop.
Jetpac takes it a step further by offering some of the biggest data packs around (we’re talking Godzilla-level), with super affordable prices and coverage on Japan’s top networks! On top of that, you’ll unlock some awesome perks, including free airport lounge access if your flight gets delayed at select airports. You can even enroll a travel buddy, too, so you both get to enjoy the lounge life together!
Using Jetpac Japan eSIM is super easy. Just scan a QR code or activate through their app, and you’re online and ready to explore! No need to submit your ID, no contracts to sign, no roaming fees - just fast, reliable internet wherever your adventure takes you.
What Is a Pocket WiFi?
Pocket WiFi is exactly what it sounds like - a tiny, portable device that gives you internet access on the go. It works like your own personal mobile hotspot, letting you connect your phone, laptop, or tablet to the internet wherever you are in Japan.
It’s a popular option for travelers, especially those in groups, since you can connect multiple devices at once. But keep in mind: you’ll need to pick it up, usually at the airport or your hotel, pay a deposit, keep it charged, and return it at the end of your trip. So while it’s handy, it does come with a bit of extra baggage, quite literally!
