They haven't had an issue that sparked this media attention*. This has been ongoing.
I went to Japan about a month ago. It was impossible to buy official packs of any set. Only place I could find them was in an official pokemon vending machine in the ikebukuro station, but the line was about 20 people long and you were limited to buying one pack at a time.
Even going to one of the largest pokemon card shops out there -- Hareruya 2 -- they didn't sell any. The Pokemon center had packs, but you couldn't walk in and buy one -- you had to pre order them (I think by lottery).
The only way you can buy cards right now is by direct resale of opened cards. Or, there's a lot of vending machines in tokyo that take opened packs and resell them in an ebay like manner across the streets of tokyo.
Pokemon cards right now are on the level of lottery tickets unfortunately.
