Re: Teaching the names of techniques.
When I first started Aikido, I was worried about the Japanese names and expressed concern to my Sensei. He just told me not to worry, that people usually pick most of it up by the time they are 3rd kyu. And I can see he is probably right. I don't know everything yet, but I am picking up things as I go along, listening to Sensei and the Sempai. Also, studying for gradings, since you can look at the japanese words and figure it out usually.
