Re: Re: Judo came from ju jitsu Did the business men come up with judo because they thought ju jitsu was too violent? Samurais are the US Navy Seals, british Special air services, french GIGN of their time. They Ate slept and breathed combat. From swords bows to hand to hand combat. If you wanted to learn a self defense style wouldn't you rather learn from a people who centered their whole lives around it?
