The price per GB, at a glance
Based on the 50 GB plan: the shorter the bar, the less you pay per gigabyte.
With PlanJapan, 50 GB valid for 30 days costs €34.99, that's €0.70/GB — and data plans start at €13.99 (10 GB). Let's be honest: Saily runs frequent promotions on small volumes — if you're going for a short trip with a very small plan, compare case by case. On a real stay, the gap per GB stays around ×2.9.
And that's not all: every PlanJapan eSIM includes the Japan Guide (70+ pages) and the Google Maps map (200+ spots) — that's €29.98 free, added automatically to your order. Not forgetting −5% from 2 eSIMs and −10% from 3, applied automatically at the cart.
To each their eSIM
Saily isn't a bad eSIM — it's a serious generalist, backed by Nord Security. Here's when it makes sense, and why PlanJapan wins on Japan.
When Saily is a good call
- Your trip hops between several countries: a generalist eSIM covering many destinations can make sense
- A modern app, backed by Nord Security (the company behind NordVPN)
- Frequent promotions on small volumes, useful for a short stay
- English-only support isn't a problem for you
What makes it awkward in Japan
- No genuinely unlimited plan for Japan
- One of the highest prices per GB in the panel (≈ €2.04)
- Chat support in English only
- No Japan specialisation (guides, tips, network)
Verdict — Another decent eSIM in the app store — nothing built for Japan specifically.

Why PlanJapan wins on Japan
- 100% dedicated to Japan: NTT docomo 4G/5G network, 99% data coverage
- Genuinely unlimited, no speed throttling — and unlimited tethering included
- No blocked apps: TikTok, Instagram, banking apps
- €0.70/GB on data (50 GB at €34.99), unlimited from 10 to 30 days from €29.99
- Japan guide + Google Maps map free (€29.98)
- Buy without an account, QR code by email in 2 min, flexible 180-day activation
- Support 7 days a week, satisfaction guaranteed
Verdict — Built for a single destination: yours. That's the whole difference with “worldwide” eSIMs.
Our take. If you're planning a trip to Japan, you've certainly come across Saily: the eSIM launched by Nord Security, the company behind NordVPN. A modern app, frequent promotions on small volumes, destinations all over the world — let's be blunt: if you're hopping between several countries on the same trip, it's a serious option.
PlanJapan plays in another category: a single destination, Japan. A single network — NTT docomo, the country's number one carrier — plans designed for a real trip (unlimited from 10 to 30 days, unlimited hotspot), a guide and a Google Maps map included free, and support 7 days a week. That specialisation changes everything at the exact moment you need it: on the ground. If you want to look wider, our full comparison of Japan eSIMs also puts Airalo, Holafly, Nomad and Ubigi under the microscope.
The detail that changes everything when travelling together: with PlanJapan, tethering is included with no limits on every plan, and unlimited data comes with no speed throttling — Saily doesn't offer a genuinely unlimited plan for Japan. See the unlimited eSIM →
