Every competitor, under the lens
What we honestly credit each one with — and what falls short once in Japan.
PlanJaponThe Japan specialist
from0.70 €/GB
What makes the difference
- 100% dedicated to Japan: NTT docomo 4G/5G network, 99% coverage
- True unlimited with no throttling + unlimited hotspot
- No blocked apps: TikTok, Instagram, banking apps
- Japan guide + Google Maps map free (€29.98)
- Support 7 days a week, money-back guarantee
Verdict — Built for a single destination: yours. That's the whole difference with "worldwide" eSIMs.
AiraloThe global generalist
≈2.04 €/GB
What we like
- Well-known brand, available in 200+ destinations
- Polished app to manage several eSIMs
What falls short in Japan
- No true unlimited plan for Japan
- Almost 3× our price per GB
- Account + app required before buying
- Support mostly in English
Verdict — Handy if you're hopping through 5 countries. For a Japan trip, you pay for the global logistics without benefiting from them.
HolaflyUnlimited billed by the day
3.79 €/day
What we like
- Advertised unlimited, very visible brand
- Support available in several languages
What falls short in Japan
- "Unlimited" with a fair-use policy: speed reduced beyond a threshold
- Limited hotspot — a drawback for groups
- ≈ €53 for 2 weeks, among the most expensive on the market
Verdict — The most expensive unlimited in this comparison — with limits ours doesn't have (€38.99 for 15 days, free hotspot).
SailyThe eSIM by Nord Security
≈2.04 €/GB
What we like
- Modern app, backed by NordVPN
- Frequent promotions on small volumes
What falls short in Japan
- No true unlimited for Japan
- Price per GB among the highest in the panel
- Chat support in English only
- No Japan specialization (guides, tips, network)
Verdict — Another decent eSIM in the app store — nothing designed specifically for Japan.
NomadThe American low-cost
≈1.85 €/GB
What we like
- Decent price per GB on large volumes
- Simple purchase flow in the app
What falls short in Japan
- No true unlimited for Japan
- Network operator varies by plan
- Support in English, on US hours
Verdict — Cheaper than the other generalists, but the network experience depends on the plan — a lottery you want to avoid when traveling.
UbigiThe NTT subsidiary
≈1.85 €/GB
What we like
- NTT docomo network — the same excellent network as ours
- Solid company (NTT / Transatel group)
What falls short in Japan
- Account + app required, heavy purchase flow
- No true unlimited, expensive top-ups
- Limited support, aging interface
- 2.6× our price per GB, zero gifts or guide
Verdict — The right network… at a high price and without the guidance. We keep the same docomo, in 2 minutes and 2.6× cheaper per GB.

Torn between us and one particular brand? Here are our head-to-head comparisons, with prices from the official sites and identical criteria.
Compare, with full clarity
The one that ticks the 4 boxes that matter on site: the network (NTT docomo is Japan's #1 carrier), true unlimited with no throttling, the price per GB, and support in your language. PlanJapan is the only one in this comparison that ticks all four.
The eSIM, unless your phone isn't compatible. Pocket wifi costs €70 to €110 for 2 weeks, must be charged every night, picked up and returned at the airport with a deposit. The eSIM installs in 2 minutes before departure.
It depends on your carrier: some plans include a limited volume of data in Japan, others charge €5-15/day passes — and overage is very expensive. Check your contract carefully before leaving.
Not always: several competitors apply a fair-use policy (heavily reduced speed beyond a daily threshold) and limit the hotspot. With PlanJapan, unlimited means no throttling and hotspot sharing is included with no limit.
Prices and features are collected from each brand's official website (July 2026), for a comparable Japan plan, converted to euros. Offers change regularly — if you spot a discrepancy, write to us and we'll fix it.
