Re: Is is it still Aikido if you take away the Japanese clothes, etiquette and other things?
My point is that uwagi is not "traditional training clothes," otherwise it would be worn by koryu for demonstrations. So if it is not traditional, where is it from? It comes from Kano, who started a trend away from wearing regular clothes to wearing specialized training clothes.
Kano adapted the jackets used in Cornish/Gouren styles of wrestling. Judogi is european in origin. There's no collar & elbow grip tradition in japanese jujutsu.
