Hi, Brian,
This will be discussed from time to time, and there will always be differences "read in" to what was said by the Kodokan committee.
I have that issue as well, and although very tired and tattered due to my neglect, I have never understood it to mean that Kano graded himself to anything.
This book, and even more so late edtions, say different things about when and how Kano "graded" himself. I just ordered a book which now has been reissued and one I have never owned, but we will see. These same people in committe at the Kodokan in the fifties have also said, though not included in this manual, that Kano berrated his students for attempting to rank him to any level, and to do so, he would put it out of reach, IE, that if he were given tenth dan, he would raise it higher, etc. These manuals from the Kodokan are just that and do have many contributors, ones who thought Kano a "genius" and should be held out in some form or another apart from ordinary judoka.
Now if we consider that Kano has also stated that judo must be learned as he instructed, and in the order in which to learn waza, it is also said that he made nage waza to be most important if the other waza were not available. Personally, since this book, in all its variations says this, and that Kano said, paraphrased, that to stop judo training is not to be tolerated, among other rules. As this is not possible for most for a lifetime, the additons have added these caveats to make it comprehensible. There is very little about Kano which is quoted and witnessed. His only goal was to teach judo, and he lamented the lack of qualified teachers before he died, so when he says that a return to "Kodokan randori" is of immeditate importance, is this to mean his randori or that praciticed by people who have studied at the Kodokan? In his later years, he spent little time there. Much can be opined to what this meant, and therefore, much of what the Kodokan itself said concerning Kano and what his thoughts were, is to be taken only at face value. It can be interpreted that he promoted himself to junidan or shihan or whatever, but no one has specifically quoted Kano as announcing this to all to here, otherwise, it would not be in such dispute.
This is only my opinion, but when someone says that Mr. Kano did just that, as are the stories which came out of the daito ryu "history" which claim certain waza which can only be "demonstrated" by master and a trained uke, as to do otherwise, would be dangerous for anyone who wanted to experience one of these techniques. Also, T. Takeda also said is father was a "wall passer." Of course there are no such claims about Kano. He also never mentioned the "soft" judoka, but this is making a comeback, if for no other reason than to say that this is what Kano meant by the constant of "mimimum effort and maximum efficiency." He is said to have been very unhappy the direction judo had taken, and repeated what he meant that one must never use brute force to do well in competition, that waza will win out and strength should be centered only in the shoulders and hips, and then only in the instant required to achieve kake, or whatever the technues one was utilizing in randori. But just like in ryu of jujutsu, time has a way of changing things to fit our vision of the world, and the soviet judo players proved, at least in winning, that size does matter, thus the need for weight classes and the removal of the openweight divisions. This is contrary to what judo is about, but the facts are what they are. Personally, I can't wait 'til this adage is fact, and it is, if you are in judo for the long haul, when the two or three techniques one uses in shiai no longer hold up in the real world. There are many now who have no interest or cannot physically compete, but the number of schools which do more than touch on self-defense kata (goshin jutsu) or even nage no kata, or participating in kata tournament are nearly inpossible. I have run into some who have many years of judo training, and when the discussion hits on "well, what about atemiwaza no kata," and the usual description of what they do does not involve striking in any way. This is truly one of the sadder commentaries on judo today, but I know you have a vast storehouse of knowledge, and this, of course does not apply. It is only an example of what can happen when someone takes the term "forbidden" and then does the same with these forms, literally. The Kodokan is not innocent in this.
The other day, I was making my monthly tour of the judo forum at http://www.ijf.org and the question of "jumping juji-gatame was again raised, as someone wanted to know if it were legal. I am only certified in my state to officiate at shiai, but the rules clearly state that if a true waza was not attempted to bring uke to the mat, then "dragging" an opponent from the standing position to katami waza is not a proper move, and can be dangerous, as well. If one can grab an armlock and then uke goes to the floor because he is resisting, then that is different. Here is a good example of "a judgement call," as some will not allow it but others will. Personally, dragging someone to the mat, or jumping into a mat technique such as this which is cinched before uke gets there, he/she will get one warning (if a point tournament-we don't have many here) than an immediate keikoku is called and the opponent, or victim, gets credit for waza-ari. Either way, do it twice and you are out of the tournament (direct hansokumake). I have heard this story beginning in the sixties and there is still an argument, not over the technique, but what is achieved as an attempt before the armlock. Otherwise, it is a very nice move, and one I approve of, but only in context of self-defense. That's just me My point was (sometimes I forget to make a point) that one person had called the Kodokan about it and asked Murata, curator of the museum there, and that he had said it was perfectly within the rules. Mr. Murata has answered a few questions of my own, and is very nice, but the Kodokan long ceased to be rule maker, as the IJF makes them today. I am sure he deserves his nanadan very much, but to answer so flippently about something which is not his territory, is not the response I would expect. Instead, I would give the name of the head shimban or officiating body of the IJF, or the person's national organization to answer that (referee training and seminars are held, at the least, once a year, and too many times in this isstance of the Olympics).
So while I would like to believe everything attributed to Mr. Kano to be true, some are not, and I doubt seriously, a man of Mr. Kano's stature (he was the same height as me ), would announce than he is now shihan, junidan, or anything else, as he had always intended the white/black belt, and possibly brown, to be a watermark of where your level in training is located. As Kano applied the "circle of judo" to mean the same thing in life, then the only thing a "perfect" judoka could be after attaining this perfection (10-dan), is to be a student again, and though it is possible, he wanted no part in his many students' plans to grade him there as he believed perfection could not be achieved, but if so, then eleven and twelve would be the first of this new class of student.
Anyway, sorry for the long and drawn out post, but I like the subject, and I fight for judo to be accepted as it was meant to be. "To better one's self." This can be accomplished in many ways, and he had strived to make this pleasing, but totally unimportant in the scheme of things.
My two c-notes
Sincerely,
Mark
