Intresting, wich Takemusu associations would that be? Since both the Takemusu Aikido Acc in USA and the Takemusu Aikido Kyokai in europe is affiliated to Aikikai. And my impression is that also the "Iwama group" in CAA also maintains strong links to the Aikikai.
Well, there is no need to point fingers but I can tell you the said dojos are located on 3 different continents. My (previous) sensei's reaction when I told him was that Takemusu was part of the aikikai and he was very surprised at this kind of disrespect to the son of the founder.
