I'm trying to make a list of all e-cards from Japan. Here's what I have so far:
Pikmin 2 (6 packs)
Rockman Battle Network 4 (4 series)
Doubutsu No Mori e+
Pokemon (I don't know or care about specifics)
Pokemon Battle-e
Mario Advance 4
Hamtaro
Domokun

Any others?

(Oh, and if anyone has any Japanese e-cards for sale/trade, PM me please)
