Along with his wife, Kaz founded Kuzui Enterprises, which distributes US films in Japan, and imports Japanese films for the US market. In addition to holding a portion of rights to the Buffy the Vampire Slayer character, Kuzui was also given an executive producer credit for the TV series and its spin-off Angel, despite having no practical role in either production.
Kuzui intends to relaunch the Buffy franchise without Joss Whedon, the man who created the original concept.
