Why is Miyama Ryu called Combat Jujutsu?
When we say combat we mean defense against attacks as they would actually occur on the streets. Some Jujutsu styles have perpetuated the myth that fighting someone for 45 minutes on the ground is self-defense. Of course your own common sense would tell you that rolling around on the streets of New York or any major city for 45 minutes with an armed attacker or multiple attackers would mean certain death.
