One thing I have wondered about, not really being too familiar with ****oryu, is why did many of the followers of Tani stop calling their practise 'Shukokai'? What was 'Shukokai' in relation to ****oryu? (All I know is it came about from Tani's school and had an emphasis on innovative new, for the time, training methods.) Are Shukokai kata different, or is it just how some of the kihon is done? Was it abandoned or is it just that the name Tani-ha ****oryu became preferred?
