Reviews

Worked well and arrived at our hotel on time and was easy to return. With the additional battery we ran it all day with no loss of connection.

Lasted all day. Worked everywhere. Loved it. Would use again.

The WiFi worked perfectly.

Reliable all the way through our 10 day trip.

Was impressed and it handled 3 devices.
The little back battery needs to be either replaced or more power as it didn’t last long. The battery life of the device was just enough us, often just used the hotel usb ports.

Werkt fantastisch, maar vooral tevreden over betrouwbare informatie, moment van ontvangst en accessoires. Voor 100 % aan te bevelen gedurende een vakantie in Japan.

I travel to Japan twice per year, typically staying 4–5 weeks each visit, and for the past three years I’ve consistently used Japan Wireless Premium WiFi. Simply put, the service has been outstanding.

Coverage throughout Japan has been exceptional — from Sapporo to Kagoshima — including on Shinkansen trains, subways, inside major city centers, and even in large glass hotel buildings where signals often struggle. Connection drops have been extremely rare, likely less than 1% during my combined months of use, and usually tied to temporary transit or tunnel situations.

I generally connect three devices simultaneously — my notebook computer, iPhone, and Apple Watch — and have never experienced performance or stability issues.

The delivery process is equally impressive. I always have the unit shipped directly to my hotel, and every single time it has either been waiting at the front desk or already placed in my room upon arrival. Very professional and reliable.

Returning the device is effortless. They provide a prepaid, self-addressed Japan Post return envelope. You simply drop it into any Japan Post mailbox or leave it at one of the major airports before departure.

Excellent pricing, outstanding reliability, and consistently strong coverage across Japan. I highly recommend Japan Wireless Premium WiFi to anyone traveling throughout the country.

5 out of 5 stars.

Very good and convenient

The product was reliable and the battery lasted through the day even as we traveled to some isolated areas.

Works very well and it’s worth the price. Easy to pick up and return
