now i have watched many judo students go at it with each other but how would it do on the street in a real fight? Im not sure. I know that if you practice something long enough it becomes effective.

Yes is the short answer. If you practice long enough and learn your techniques and throws well it will be very effective against a SINGLE PERSON. Using JUDO in a fight will result in you taking them to ground. If there are multiple attackers this is the worst thing you could do. As always, remember thatr the best self defense is not being there at all. They cant beat you in a fight if u are not there to beat.JUDO is an effective martial art. Train hard and you will go far.

judo is great to use in the street if you are being attacked. Like John said a throw to the ground hurts like hell and once they feel it they wont wanna come back for more

well I only was in judo for awhile almost a year maybe.. But I agree that if you were in a fight against multiple opponents you would be ..well in a lot of trouble.. especially since if you tried a throw you would be kicked or beaten to the ground.. anyway even against one person I think it would be ok but you would also need to punch and try to damage them before they have a chance to get you.. and if you do slam them into concrete it would hurt but I know guys who would get back up and hurt you.. plus you might have some trouble getting into postition since when you are in a tournament you dont have to worry about a knee being driven into your ribs or strangled , beaten in the head face,etc. so it would be against someone who has an unexperienced fighter but anyone who is confident in themselves and not afraid to attack may be difficult.. but then again I dont know an exceptional amount so don't go by only my opinion.

Thinking about it, I think Judo would be better for the street than BJJ because of Judo's priority on throwing. Where as BJJ is takedown to ground. I have known of a few Judoka who did well in a street fight. Ed

using judo against one assailant can be devestating. a tai-otoshi throw will, when done properly, destroy your opponet. but, as stated earlier, if someone is lurking in the shadows, it may get dicey.

[Here is where I put something witty about suffering fools or somesuch]

Just ask a black belt judoka to spar. You are getting thrown, yes? A little rattling, even on that soft mat, no?

There you go. There's your answer.
