If it's a "Goshin-Ryu Ju Jitsu" dojo then it's not MMA. The latest trend is for traditional martial arts schools who teach styles that are "mixed" to claim that they are teaching MMA. Yes, technically they are teaching a mixture of martial arts, but they are not teaching Mixed Martial Arts.
Exactly like my dojo for kickboxing-kickboxing is obviously American Freestyle Karate but we wear gis, do our "kelow" and "sezat" bows and say "matay" to stop. We have kata too. But you can tell our club is based on a mixture of martial arts due to the fact that we teach Jiu Jitsu techniques at Black belt and also because Lau Gar Kung Fu is Chinese, not Japanese (Lau Gar Kickboxing is what we actually do though-it's pretty much kickboxing in a Lau Gar organisation)
