PlanJapan
VS
Airalo
Airalo is probably the best-known eSIM in the world: available in 200+ destinations, with a polished app. PlanJapan covers a single destination — Japan. Price per GB, unlimited plans, network, support: we put the two head to head, with figures taken from the official websites. And we tell you honestly when Airalo is still a good call.

Prices and features recorded in July 2026 on the official websites, for a comparable Japan plan (≈ 20 GB / 30 days, or 15-day unlimited), converted into euros. Airalo's offers may change. Daily data limits were re-checked in September 2026 on each brand's official pages.
Many “cheap” eSIMs use routing that blocks TikTok, banking apps or SMS verification. Ours uses the real Japanese NTT docomo network: everything works, just like at home.
Based on the 50 GB plan: the shorter the bar, the less you pay per gigabyte.

0,70 €
Airalo
≈ 2,04 €
Concretely: our 50 GB costs €34.99 (€0.70/GB). The same volume at ≈ €2.04/GB with Airalo is a far heavier budget — for the same data, on the same trip.
Good to know: −5% from 2 eSIMs and −10% from 3 or more, applied automatically at the cart — no code to enter. And every eSIM includes the Japan guide (70+ pages) and the Google Maps map (200+ spots), worth €29.98, free.
Airalo isn't a bad eSIM — it's a generalist eSIM. Here's when it makes sense, and why PlanJapan wins on Japan.
AiraloThe global generalist≈ 2,04 €/GoVerdict — Handy if you're hopping between 5 countries. For a trip to Japan, you're paying for global logistics you won't use.
PlanJaponThe Japan specialistVerdict — Built for a single destination: yours. That's the whole difference with “worldwide” eSIMs.
Our take. Comparing Airalo and PlanJapan means comparing two different jobs. Airalo sells connectivity everywhere: more than 200 destinations in a single app, standardised data plans, impressive global logistics — and that's what you're paying for too. PlanJapan does exactly the opposite: a single destination, Japan, with everything optimised for it. One network — NTT docomo, the country's number one carrier — genuinely unlimited data with no throttling, a travel guide and a Google Maps map free with every eSIM, and support that replies 7 days a week.
The result: for a trip to Japan, the specialist beats the generalist on every criterion that matters once you're there — and often for far less. The real question isn't brand recognition, it's what happens on the ground: network, speed, tethering and support. It's spelled out in black and white on the product page.
The detail that matters when travelling together: with PlanJapan, tethering is included on every plan — handy for connecting a laptop or a travel companion's phone. How to turn on the hotspot →
Looking for Airalo reviews for Japan? Here, side by side, are those from travellers who chose PlanJapan — 4.9/5 from 1,500+ verified reviews, collected after a verified purchase.
“I hesitated for a long time, there are so many eSIM options for Japan! I went for the 15-day unlimited plan: everything was perfect, both for Google Maps and for social media. I'd do it again without hesitation, thank you so much.”
“Extremely happy with this eSIM, I highly recommend it. I visited several cities and had no network issues, no need for a VPN unlike other eSIMs. Unbeatable price and excellent after-sales service.”
“Trip in April 2026: easy to use, no network problems, very happy. One of the 2 eSIMs wasn't compatible with my daughter's phone: refunded within days. Great. PlanJapan offers some of the best value for money.”
Airalo isn't the only alternative: here are our other comparisons, done with the same method — prices from the official websites, identical criteria.
