Purchased the wifi before arriving in Japan. Picked it up at the Ninja Wifi counter on the 3rd Floor in Haneda Airport. Had great wifi during my entire stay, and very easy to use. And the return was so simple: there’s a JP Post mailbox right in the departure area, so you can use the wifi up to the point you’re about to go through TSA. Also got an email confirmation that they received the return that same day. 100% recommend!!

Device is the right size for a small sling bag, battery life is so good you dont even need to used the powerbank that theyve provided. Internet speed is as advertise. All in all a pretty good deal.

The portable WiFi was amazing throughout my whole trip. It was delivered to my hotel before I arrived, so I could use it straight away. Easy to setup and nice a small to carry around. Then just posted it back as I was leaving, it couldn’t have been easier!! Great service!

Great service, good coverage, easily connected 4 phones, battery life good

If you don't have a good roaming data plan with you phone provider this is a must. I had great signal everywhere I go, even in the subway. No hassle getting and returning them too. Their booth right before you exit Narita Terminal 1.

I was reluctant at first dealing with a company I wasn’t familiar with in Japan. However, I got my device at my hotel on the day and time I needed it. I emailed my questions and concerns and they responded back promptly. The device gave me no problems. Conveniently , I even mailed my device back at the nearest mailbox near the hotel I was staying at before I left for the airport.
I would order from this company again.

Excellent service and very well worth.

Never disconnected unless lowbatt. Reliable.

My wife and I got japan wireless wifi and was amazing, even at the top of the senbon torii we got signal. Best option. We will use it when we return to Japan

We were able to plan routes & trains as our day unfolded from wherever we were!!

The wifi was perfect in tunnels & buildings for the whole week in Tokyo!! Great & very cheap!
