-kyo vs. -kajo
Hi all, since I started out in JuJutsu rather than Aikido, I learned the initial control techniques as:
Ikkajo, Nikajo, Sankajo, etc.
In Aikido, I know them as:
Ikkyo, Nikyo, Sankyo, etc.
Although I do have one of Shioda sensei's books, and I notice that he too uses the -kajo version.
Is there a major difference between these words in Japanese?
