Lame excuse. Musashi isn't wearing a judo uniform. With basic kana reading you can understand "tai kikku" (thai kick) in the dialog box. Hell, how could a judoka grab an opponent wearing boxing gloves? (Flashbacks of Balrog pressing buttons in American cartoons coming back).
You could confuse it with kickboxing, but there's no way judo could be into the mix. That is the equivalent to screaming "home run" at a soccer event.
