Like a Dragon: Ishin!

Despite there being 4 methods of combat (Brawler, Swordsman, Gunman, Wild Dancer), there are only three masters of combat. The Komaki Dojo (just East of Teradaya) will teach you Brawler moves, Unyuan (North of Teradaya) will teach you Gunman moves, and the Ginryu Dojo to the far Northeast will teach you moves for both Wild Dancer and Swordsman.

It's worth noting that you need access to Rakunai (the most northern part of the map) before you're able to access the Ginryu Dojo which happens by Chapter 3
