Gelatoni, where are you located? Hong Kong? It sounds like you're talking about in-person trading. If you are in Hong Kong, are there a lot of Japanese tourists who come over? I have the hardest time even finding Japanese traders.
I had a friend in Japan for a while who would swap stuff with me, and I know a few that come to the EPCOT event every year, but otherwise, it's so hard to find info on them. I even asked once if there was a board or forum in Japanese, just to see if I could pre-trade before going over, and I was basically told that there's no real "community" of traders in Japan, that they just all do their own thing. Do you find that to be true?
Oh, and I don't mean in-park/cast trading...I know the story behind that and all. I mean traders like all of us.
