Though I had been to Japan before, and despite being obsessed with video games, this was my first trip to a Pokemon Center in Japan (I had previously visited the Nintendo World Store in New York, which has a Pokemon Center in it). They had a LOT of Pokemon goods for sale, some exclusive, some more common. On this particular day, if you brought your DS and a copy of Black 2 or White 2, they were giving away one of the Legendary Pokemon!
