Mobile Wifi rental at Narita Airport

Hi lovely people of Japan Guide, I have a question and although its been asked many times a lot of the threads are out of date.

So pretty well as the question asks where at Narita airport (terminal 2) is the best to be able to rent a mobile wifi device from and be able to give it back in at on the way home after my two weeks holiday is over???

I`d mainly be using for communication with family and loved ones (I.e Skype and emails) as well as to a lesser extent for guidance and help on a few things to do etc.

Again sorry for the repeat of the question but I`d like more advice on the matter thats more recent :)

I've heard some good reviews about the services of Global Advanced Communications

Global Advanced Communications are the absolute best.
Order it online, and it will be waiting for you: they will supply you with the pick up location.
They also supply the return envelope: at Narita 2 there is a post box opposite check in area #5.
We have used this service twice now, and couldn�ft recommend it highly enough.
The 72mbps router was so quick, and we had no trouble using it at all.
We didnt go for the 2nd battery, as the 72mpbs battery lasts for 10 hours continuous usage.....
Have fun with it!!
