Re: Best karate style for aikido?
I agree with Sean about Kyokushin Karate. I started training Kyokushin Karate and had been training for a few years when I found Aikido. I trained both for eight years and found them very complimentary to each other. Kyokushin was not linear and was a circle & point style of Karate - okinawan based.
I would still be training both but a foot injury forced me to give up Karate, but it still resonates in my Aikido Training and life even now.
I must also say that the statement that Aikido is Akido and Karate is Karate is not what I understand either to be. There are so many different representaions of Martial Arts and Schools that call themselves Karate and are really Tai Kwan Do etc
You need to find the style that is right for you and it is possible to successfully train two Martial Arts and thrive from both.
