Just curious if anyone has either bought or seen this SIM card for Japan while in Taiwan. It would be much more convenient (and appears to be cheaper) to buy this SIM while still in TW before leaving for Japan to save one extra task before getting on the train into the city.

I've been to TW multiple times since this announcement, but never saw one of these SIM cards, but I didn't know where to look for it before.
