I returned to Nagoya in November to "finish" sightseeing and make the local card shop rounds. I discovered A-BITS the first time I visited, but a lack of funds kept me from really exploring the shop. This time, I came back with a good number of cards.
The owners of the store are very nice! They recognized me from my visit about six weeks earlier, though I guess they don't get many foreigners. I started a point card (hopefully I'll be able to finish it on a subsequent visit) and they were kind enough to award me with a 500 yen coupon for my next visit. I plan on returning to Nagoya once the baseball season resumes so I can catch a Dragons game.
