the last time i checked, the jusan kata is still a very integral part of the Iwama jo curriculum. i attended a seminar just last year where Sensei Stephanie Yap gave a very detailed instruction on the solo adn paired practice of jusan. she said (as i best remember) that the jusan paired practiced can be practiced wiht up to four partners, or, with slightly modified footwork (no turn on hasso no gaeshi), can be practiced with a single partner. it was very clear from this seminar that jusan hasn't gone anywhere and isn't going anywhere anytime soon.
to the moderator: you made very interesting statements in a previous post saying that aikijo and aikiken lack certain elements to make it as readily applicable as most koryu jodo/jojutsu or kenjutsu. if i did understand that correctly to be your point, would you be so kind as to reiterate what you said? also, how much of aikijo/aikiken do you personally feel would be effective as learning koryu jo or ken? if a person such as myself (who has no one in his area doing koryu) wanted to get a better idea of teh differences between aikido bukiwaza and koryu bukiwaza, what would you suggest?
sorry to pester...
