When I first booked my trip to Japan, I figured the toughest choice would be deciding between the serene temples of Kyoto or the vibrant nightlife of Tokyo. Little did I know, one of the biggest challenges would pop up before I even started packing: how on earth do you stay connected while in Japan?
There’s a ton of advice floating around. Some folks are all about pocket Wi-Fi, while others swear by grabbing a local SIM card right at the airport. And then there’s the new kid on the block — the eSIM. Wanting to dodge those pesky roaming fees and connectivity issues, I decided to give all three options a shot during my travels. Here’s how each one stacked up — the good, the bad, and the surprisingly simple.
1. Free Wi-Fi in Japan: More Hype Than Help
In theory, Japan boasts decent public Wi-Fi. You’ll spot signs for it in convenience stores, cafes, and major train stations. But relying on it as your main source of connection? That was a misstep. Most networks had a sign-up process, think entering your email or logging in through Facebook, and many would kick you off after just 15 or 30 minutes. I ended up spending more time reconnecting than actually browsing. One day in Kyoto, I desperately needed to pull up directions to a hidden gem of a restaurant. No Wi-Fi, no signal, and my reservation time was slipping away. Let’s say I arrived late and frazzled. Not quite the vibe I was hoping for in Japan’s cultural heart.
Verdict: Handy in a pinch, but way too unreliable for everyday use.
2. Pocket Wi-Fi: Great Coverage, Less Great Convenience
I rented a pocket Wi-Fi device for the first half of my trip. Setting it up was a breeze — I picked it up at my hotel, connected my devices, and boom, I was online in no time. In terms of performance, I had no complaints. I enjoyed a strong signal from Tokyo to Hakone to Hiroshima. The speeds were solid enough for Google Maps, video calls, and the occasional Netflix binge. But lugging around an extra gadget.
That got old pretty fast. So did the constant reminder to charge it. The battery life was okay, but I often found myself trying to stretch it out on those longer days. And when I accidentally left it behind one morning? I was cut off until I got back in the evening.
Also, keep in mind that if you misplace the unit or return it late, those fees can accumulate quickly.
Verdict: Reliable and speedy, but not the best choice for light packers or those who tend to forget things.
3. eSIM with a Local Number: Surprisingly Simple
I’ll be honest, I was a bit daunted by the whole eSIM concept — it sounded pretty technical. But it turned out to be the easiest option by a long shot.
I went with Mobal’s Japan eSIM because it provided a real Japanese phone number, which I needed for some local apps. After I placed my order and uploaded my ID (a must for voice plans), they sent me a QR code via email. I scanned it, adjusted a few settings on my iPhone, and just like that, I was connected.
I really appreciated not having to swap SIM cards or lug around an extra device. Plus, unlike some data-only plans, this one allowed me to make local calls and receive SMS messages — which came in handy more than once. I used it to book seats, sign up for a ticketing app, aend even call my hotel when I arrived late.
The coverage was solid everywhere I went, from bustling cities to quiet rural spots. Tethering worked seamlessly when I needed to connect my laptop.
Just a heads up: make sure your phone is unlocked and compatible with eSIM before you make a purchase.
Verdict: The easiest and most flexible option — especially if you want to be connected as soon as you land.
The Bottom Line
After trying all three options, here’s my take:
- Free Wi-Fi? Useful sometimes, but not reliable.
- Pocket Wi-Fi? Perfect if you’re travelling with a group or need to connect multiple devices.
- eSIM? The best all-around choice for solo travellers or anyone who values convenience.
If I had to do it all over again, I’d skip the pocket Wi-Fi and go straight to the eSIM. The ability to install it before flying, skip airport kiosks, and travel light made a big difference. Plus, having a local number felt like a small thing that made a big impact.
