Cobrai Kai is sending Daniel LaRusso to Japan in Season 3

Entertainment Weekly

"For season 3, something I can tease is that, albeit we have a lot of cleaning up to do based on the events of season 2, some of the stories will dive into the origins of both Miyagi-Do Karate and Cobra Kai,” Ralph Macchio tells EW. “Like, the beginnings of those two forms of martial arts, and we’ll learn stuff about both that we never knew. And that includes LaRusso going to Okinawa, which is a piece of season 3.”
