Barry,
Skoss writes in the Koryu Bujutsu book that there is now two branches of Tenjin Shinyo-ryu. One is headed by Kubota and an other is headed by Shibata Koichi. I belive it's highly unlikly that someone broke out and started an own organization and started awarding dan-ranks. In this case I belive at least some would have heard of it...
That Kubota should hold open seminars seams very unlikly. Tenjin Shinyo-ryu is more or less a closed system and not that open to the public (like judo for example)...The only time Kubota have had a more or less open seminar in Tenjin Shinyo-ryu was in Sweden (1998 I think). At least to my knowledge...
Regards,
Tommy
PS! Happy new year to you also Lee...Really looking forward to meet you and you family again...
