Do it!
After wasting 6000 Yen for nothing (bought a sim card but didn't work) at the airport, found this wifibox at my hotel lobby. It was a lifesaver. You may find this at the airport as well. Super fast connection and reasonable price. I highly recommend it. You can drop the thing at the airport when you leave the country. Do it!

3 times I've used WIFI-Box THE BEST
I have used WiFi Box 3 times. Every time has been excellent. Always easy to find, always helpful staff and so easy to use and return. I will always use WiFi-box! I recommend to all my friends going to Japan!

Useful
lightweight with a day's battery life, it's the essential item for planning trips to Japan and staying connected to the rest of the world without worry. Available in all airports, it's convenient as is booking from Europe.

Veryy good
It was very nice and convenient expirience to find your service at airport. I didn't know about it. I have found it very useful for my 12hrs transfer through Tokyo. Your employee at the counter at Haneda airport was kind and English speaking, which was good. Internet was sometimes off, but mostly good. I wish I have more energy capacity at your device so I can charge my phone more. Thanks!

★★★★☆
Good value for money
I used the wifibox for two 2days it was a life saver. We went to Hakone, Shibuya, Shinjuku, Tokyo, and using the unlimited Internet, plus the WiFi can be shared. My companion can also use the data. The only fault is the machine battery can improve. All in all I highly recommend this wifibox if you want to data while your traveling.
