 So when did John Crease open up the Cobra Kai dojo in the Karate Kid universe? Well, we know that according to the picture on the wall in the first film, Crease was karate champion in the army from 1970 to 1972. In season three of Cobra Kai, Robbie is reading newspaper clippings and we learned that Johnny won two out of three tournaments at that point and that was the fourth overall win for the school. So that means the school was open at minimum of five years, giving us a window of 1972 to 1979. So when did Cobra Kai first open his doors? Well, one of our viewers did a little detective work for us. In the flashback of season four, we see Crease hand silver a flyer for the seventh annual All Valley Tournament. As mentioned in Cobra Kai, 2018 was the 50th All Valley, so with a little math, we can determine that the year of this flashback was 1975. Silver responds with saying, you entered, we don't have any students yet, implying the school had just opened unless they ran for years with no students. So John Crease opened up the first Cobra Kai dojo in 1975. How's that for some nerdism for you?
