I DO have Japanese Bakugan!
all i know is that japanese bakugan have holes on the magnet and have better detail
have holes on the magnet: just for the earlier version. When SM produce it again along the show, the hole has just disappeared. (but sometimes error can occur) Korean version also has the hole.have better detail: not at all. Someone point out that Delta Drago's metal ring has more detail in US version than import (It's true for Korean version Delta Drago, but I don't know does it stand for Japanese one since I don't have 1).more difference like different font and location (sometimes) for g-power, I don't know if US b1 Bakugan have any mold number and if it does, this is probably a main difference...Japanese Bakugan seem to be no mold number...as least, less...Korean version has mold letter, not number.
he wanted to know if anyone ahd an japanese bakugan, and whats the difference between american bakugan and japanese bakugan
Oh.Well, I do not have any, and the only difference is that the Subterra Japanese Bakugan are dark brown with tan hilights like in the anime. Other than that, they are identical.
dark brown Subterra is just for the earlier Japanese version before Bakugan show was released. It is now very rare, and I really want a dark brown Subterra Saurus!
