best chances are
A: go to japan and scour the hell out of small record shops. handout stuff shows up alot
B: use a auction service and try yahoo! auctions japan
C: make friends with someone in japan and have them search for you
Ah, no longer unfortunately, I'm back in Australia now... sorry! Since it appears to be a handout/freebie I'm not sure of any online Japanese shops/distros that might carry it (these places and their websites are hard enough to find in the first place, argh).
Hmm, no chance you could pester the Cyclone Records folks into sending one over...?
