Currently there's no plugin available as far as I know, but just keep checking this page daily and if a plugin comes out it should be listed right at the top:

That makes absolutely no sense, as there are TONS of Japan exclusives that have cheat plugins available all over the place... It's not because it's Japan exclusive, it's because it's a very new game and searching and modifying values while testing to make working cheats takes a while.
