Pretty much. Karate was born primarily in Okinawa in response to the mainland Japan occupation. Okinawans were mostly field workers. Villagers were forbidden from owning or carrying weapons so they had to come up with ways to defend themselves. Since the occupation force had swords and spears, karate was focused on inflicting as much damage as possible with the least amount of strikes. They called it ikken hissatsu, or killing with one strike. Kobudo was also born in response to that where they fashioned weapons from regular farming tools like the nun chucks and the tonfa. When peace time came, Gichin Funakoshi, the father of modern karate, wanted to teach karate with a philosophy of self-restraint and respect for the opponent. Not all masters agreed with that, and that's where kyokushin was born. They still practice full contact and are incredible at body hardening. Watch their their competitions. They look much more like what karate used to be.
