It's called "Kung-Fu Theater," but isn't Kung-Fu Chinese? 🤔

I'm seeing samurai, shinobi, geishas, a kabuki mask, a dojo and mention of a shogun at one point, all of which are Japanese. Granted, there are also pagodas, dragons, buddha statues and a few other things associated with East Asia in general, but the culture that seems predominantly featured is Japanese culture... They should've called it "Karate Theater" because it just seems like they're going by the typical blanketed "it's call Chinese to me" mindset.
