Thanks Granham. Nice to meet a fella Aussie on the net.
Yes indeed, I've found some similarity of throwing technique between Aikido and Judo, especially ogoshi and seoi-nage.
And here's some info on Korindo Aikido:
"Korindo aikido was founded by Master Hirai in Shizuoka, Japan ..."
"Korindo aikido is a continuation of the old style (koryu) Japanese martial art, which is a form combining body technique (taijutsu) with sword technique (kenjutsu, iai, ryuto), stick (jo, bo), and others. It bears the same root as Judo, but we do it in the traditional way"
hope someone can help me clarify this. Many thanks.
