Global Advanced worked as well as expected the end of June 2015 for my 20 yo son and I. Picked up at the post office of Narita Terminal 2 (departure level) and dropped off at the same place when we left. Like all Japan native equipment, there is the total bandwidth limit before throttling occurs. What people have not mentioned, though, is that paying an extra fee gets rid of that. Global covers that fee for you. Instructions are with the equipment telling you how to cancel the throttling out.
