Our verdict
eConnect Japan suits anyone whose trip sits entirely inside Japan, since it is a carrier selling both eSIMs and a pocket WiFi on the country's own networks. Pocket WiFi charges ¥261 to ¥481 a day and keeps 14 devices online at once.

Pros and cons
Pros
- Data caps run 20GB, 50GB, 100GB or unlimited, and the unlimited option comes with a written fair use policy rather than an open promise.
- The pocket WiFi holds 14 devices at once and shares the connection, so a group carries one device instead of a plan each.
- eSIM plans start at ¥2,860, and both formats run on SoftBank 4G/LTE and NTT Docomo 5G/4G(LTE) with instant activation.
- Collection in Japan reaches an airport, hotel, guest house, ryokan, post office or a private residence, and return is a prepaid envelope in any post box.
Cons
- Coverage stands at 1 country, so both formats are built around a single trip destination.
- Support runs on email and help centre only, and phone is not among those channels for anything urgent.
- The unlimited tier runs under a fair use policy: SoftBank can slow the speed for heavy data use in a short period and restricts speed once the total allowance is used, with the connection left on.
Who it suits
- Japan-only trips where several people need data on the move at the same time.
- Travellers who want one provider to supply the eSIM for phones and the WiFi for a shared laptop.
- Both quick city breaks and longer stays, since its stated audience covers short trip and long trip.
Who should look elsewhere
- Multi-country itineraries: Zwitchy covers 200 countries, so one plan can follow you across borders.
- Travellers after the lowest starting price: eSIMGo.is lists plans from $0.99.
- An Israel trip: SimToIsrael's plans start at $25, while eConnect Japan's cover 1 country.

Frequently asked questions
How much does the pocket WiFi cost per day?+
The daily rate for the pocket WiFi is ¥261 to ¥481, charged per day rather than as one lump sum. The same allowance list sits across that range: 20GB, 50GB, 100GB or unlimited. Short stays suit the lower end of the range, while longer stays favour stepping up to a bigger or unlimited tier.
What data allowance do I get?+
The pocket WiFi is sold in tiers: 20GB, 50GB, 100GB or unlimited. Every tier shares the same device and network treatment, so the allowance is the thing you actually choose. Top-ups are available, which helps if a group burns through a capped tier sooner than planned on a busy itinerary.
Is the unlimited plan really unlimited?+
The fair use policy sets the limits. SoftBank keeps the right to slow the connection when a lot of data goes through in a brief period, and once the plan's allowance is spent the speed drops while the connection stays live. The tiers covered are 20GB, 50GB, 100GB or unlimited.
How many devices can share one pocket WiFi?+
Hotspot sharing is supported, and the device holds 14 devices connected at the same time. That is the practical reason to carry a single device for a group rather than an eSIM in every phone. The connection comes from SoftBank 4G/LTE and NTT Docomo 5G/4G(LTE).
Which country and networks does it cover?+
Coverage is limited to 1 country, with the region listed as local. The service runs on SoftBank 4G/LTE and NTT Docomo 5G/4G(LTE), the domestic networks, so your signal follows those operators. Nothing here carries you beyond the country, which keeps the choice narrow and the pricing clear.
What does the eSIM side cost and how long does it last?+
Plans start at ¥2,860, with ¥2,860 as the reference price. The published plan list pairs a larger data pack with a shorter validity, so the entry plan suits a quick trip and a bigger pack suits a longer stay. Both formats cover 1 country.
How do I collect the device and send it back?+
Collection happens in Japan, and the listed handover points include an airport, hotel, guest house, ryokan, post office or a private residence, which suits arrivals on a tight schedule. Return is simpler: the device goes into the prepaid envelope and into any post box. The service runs under MOBILE PLANNING Co., Ltd..
How do I get help if something goes wrong in Japan?+
Support runs on email and help centre only, so questions go by email or through the help centre rather than down a phone line. Worth knowing if the WiFi is carrying your navigation, since a device fault takes a written exchange. The provider is a carrier, carrier.
