.zip password cracking

So ive got a .zip file with a password, only the password is in japanese. Ive tried brute forcing it with japanese character sets only all so far have failed. Are there programs that can extract a .zip whilst ignoring the password entirely?

Anyways heres the file http://sk2b.hp.infoseek.co.jp/cgi-bin/lime/lime.cgi?rm05a

Any help would be greatly appreciated, thanks.
