Contrasting Judo and Aikido?

Like someone said judo and aikido both come out of jujutsu. Both use the attacker's momentum against them when done correctly. Both use throws and pins(pain compliance). Both art are big on teaching students how to fall safely. Both have joint locks but different locks. However if you study judo long enough you will learn some of the basic technique in aikido as an advanced black belt.

Someone said aikido is reliant on compliance. This is far from the truth. Compliance is only done for demonstration and or safety. There is no compliance on the streets. As you advance you have to be able to perform techniques on those that don't know what you are doing and those that resist what you are doing. At least that was my experience. I can't speak for places where I have not trained. No one in aikido expect an attacker to be compliant unless you have provide enough pain. But if they don;t comply something will snap.

Judo you are not supposed to use your strength or muscle to do a technique, but often people do until they become higher skilled. Aikido stresses no strength being used from day one. It requires you to use better technique much earlier than you do in most judo dojo. Most aikido are more formal/traditional than a judo class. Exercises in aikido are generally not muscle building exercises. They mostly help teach a concept of a technique Aiki Taiso. Aikido teaches how to defend against weapons as well as use a few weapons.

It depends on the person how well they can transfer into another system. I have found that many that train in aikido have come from various others martial arts like karate, tkd, judo, etc. Many have trained many years in other arts but as they got older transitioned into aiki. The training methods/concepts are different. They must overcome that difference but after they catch on they normally progress faster than someone with no prior martial arts training. They will find that many things that are taught in their former art are present but the application is done differently. Yet they remain very effective.

Judo is quite different than other arts. But something done in judo you will find it other arts. You will generally be higher skilled at throwing because the bulk of your training is on thowong and finishing on the ground. In other art there are throws but most of the finish is done without getting on the ground. You should learn some things to do on the ground and escapes but most schools do not put as much time into it as judo or bjj or sambo.

Every martial art compliments another. Stand arts Karate (hands), Tae Kwon Do, (feet), Muy Tai (close range) as well as boxing, aikido and judo are your ground fighting. You can use it all so what ever you end up liking more. Try out a few classes of each, find a school and instructor you like and commit.

Judo's focus is grappling and the hardness is full contact. Judo means 'gentle way'. Its most prominent feature is its competitive element, where the objective is to either throw or takedown an opponent to the ground, immobilize or otherwise subdue an opponent with a pin, or force an opponent to submit with a joint lock or a choke. Strikes and thrusts by hands and feet as well as weapons defenses are a part of judo, but only in kata and are not allowed in randori. Judo's principle is: 'Resisting a more powerful opponent will result in your defeat, while adjusting to and evading your opponent's attack will cause him to lose balance, his power to be reduced, and you'll defeat him.' Judo places a lot of emphasis on use grappling and throwing to basically use your opponent's momentum against them.

Aikido's focus is grappling and the hardness if actually softness. Aikido means 'the way of unifying with life energy'. aikdio is an art that practitioners can use to defend themselves while also protecting their attacker from injury (*******). Aikido is performed by blending with the motion of the attacker and redirecting the force of the attack rather than opposing it head-on. This requires very little physical strength, as the aikidōka leads the attacker's momentum using entering and turning movements. The techniques are completed with various throws or joint locks. Physical training goals pursued in conjunction with aikido include controlled relaxation, flexibility, and endurance, with less emphasis on strength training. In aikido, pushing or extending movements are much more common than pulling or contracting movements.

High level judo and high level Aikido are principally similar.

You can understand Aiki in Judo, just as good Aikido is rooted in jujutsu.

At the get go, Judo starts from a set of rules designed to promote safety. Aikido trains you to be safe.

Judo Gokkyo and Kime kata are antiques from the lineage of Jujutsu and are basic techniques compared to Aikido waza.

Now, to counter act the other posters... Aikido will not transition to MMA. Aikido is neither a sport nor does it adhere to a sporting concept.

There is, however, randori in both arts, they just take on different meanings. In Judo, randori is a contest, in Aikido, it is a response test.

Aikido has Ne Waza and is based on kansetsu waza, however the aim is not to prostrate yourself pinning an opponent. Aikido aims to keep the practitioner open to multiple opponents, something Judo doesn't train students in.

I study Hakko Ryu Jujutsu, which shares the same lineage and a few techniques as Aikido, so I understand the finer points of Aiki and pins.

I also recently took up Judo to improve my nage waza.

There are merits to both.

judo and aikido are completly different.( i trained both). first of all aikido is not sport it is martial art. Judo used to be that but nowadays it is considered competetive sport. Aikido is used for self defence and there arent typical judo throws in aikido. I personally did aikido because i thought it was cool to know some intersteing moves. But in general aikido is not transfarable to MMA or street fighting. So its pretty useless. Judo is much more aerobic and explosive sport. It has nothing to do with aikido. Watch some judo fights and u ll see what judo really is. It is considered of throws and contra throws. Who first falls on back that one loses. There is also ground part of judo game which is completly enigma for aikido. Judo has also typical submissions like armbars triangles and kimuras whereas aikido isnt focused on that. Aikido is completly unusefull for me but while training it u feel very good haha

Both styles came from jujitsu.

Both use grappling.

Judo uses ground techniques and kicks (low) more than Aikido.

Aikido has more "leading" techniques, judo goes for a faster take down.

a lot of early aikidoka transitioned from judo. look at tomiki aikido. it kind of fuses the 2.
