I've been training in Judo for about 3 years with a couple of clubs under the Scottish Judo Federation but have recently started training in a club which is affiliated to the Brittish Judo Council. The first major difference is that the BJC state that they teach kata from blue belt and that the SJF don't until 2nd Dan. But to me it seems that the sets the SJF do for their grading greatly resemble the katas that the BJC teach. The SJF sets are even called something like Go No something kata (sorry my japanesse is still very dodgy even after all these years). What I'd really like to know is when do sets or combination attacks become a kata? Does it have to be throw for throw? p.s I've heard about a breakfall kata, I think its called 'The falling leaf kata' has anybody else heard of it?
