The principles applied to Judo and Aikido are not the same. Judo ;when pushed /pull.When pulled push.Aikido when pulled;Enter .When Pushed :turn and push.As a long term judoka/aikidoka you will be mixed up if you apply Judo principles to aikido.In the first place the posture is different, the maai is different and the initial contact with uke/control of uke is different.Judoka close the maai and due to their posture [shizentai etc ] they can be kicked /punched fairly easily before/on establishing contact.Of course once contact is established
a throw can be set up or if the encounter goes to the ground the judoka can apply ne waza.Judoka in general do not train in atemi.
As a footnote most if not all my own teachers were Budo trained.Judo to me is closer to Iaido/Kendo in tai sabaki / foot work.Aikido uses hamni /judo shizentai +Jigotai.
Thanks for the info Joe. Tomiki Aikido was developed for Judo players. It follows those principals. Although the techniques are different looking, a principal is a principal and you have to understand what is happening in terms of off balance etc.
For instance, take Kote Gaeshi and Osoto Gari. They look totally different but they really aren't. You can get Uke in the same position with either technique. It's the off balance that puts uke in a certain position. That's how I see it.
I have a book from 1957 that Kenji Tomiki wrote entitled Judo and Aikido
. Chapter 4 is titled "Explaination of Aikido Techniques According to the Principals of Judo
They are very similar you just have to look at it from another angle.
