A couple of visual cues subtly place the climactic All Valley Karate Championship of The Karate Kid at Christmastime. When Mr. Miyagi (Pat Morita) accompanies Daniel LaRusso (Ralph Macchio) to the Cobra Kai dojo in an attempt to stop the attacks on young Daniel-san, militant sensei, John Kreese (Martin Kove), demands that Daniel fight his best student, Johnny Lawrence (William Zabka). With Kreese having a perceived advantage in his own dojo, Mr. Miyagi motions towards a poster on the dojo wall for the under 18 All Valley Karate Championship taking place at State University on December 19th. Upon checking in at the tournament, shot inside the Matadome at Cal State Northridge, red, gold and silver tinsel line a wooden trophy case and a flocked Christmas tree can be glimpsed in the background.
