ok i was wondering if there was a japanese virsion of limewire or something similar to it?

You DO know that limewire is illegal, right? :\ I've never heard of a japanese version of it though.

Lime wire is just another P2P file sharing program, just like BitTorrent, the program itself isn't illegal. However, using it to share copyrighted music, games, etc. is.

You don't really need a Japanese version of lime wire though. :\ File sharing is still file sharing no matter which way you look at it. There probably is one out there though, but I never heard of one.
