So my constant pointing out that every single thing you typed was wrong didn't sink in, huh?
More like semantics. I'm pretty sure that I said that Judo is a modernized form of Jujutsu. In fact you quoted me saying that.
It's not semantics, it's accurate history and terminology. And yeah, you said that Judo is a modernized form of Jujutsu... you did pick up on the whole "So, uh... no. Wrong" motif, yeah?
In other words, Judo is not (repeated here for emphasis) NOT "modernized" anything. It's Judo. Which is a form (repeated here for emphasis) ONE FORM of Jujutsu. While a number of it's aspects have been adopted by other modern systems, that doesn't mean that Kano was "modernizing" anything... he was simply adapting what he knew to a particular context (which was to do with ingratiating Judo into schools and the education system, nothing to do with "modernizing" anything, other than matching an evolving education system).
Again, semantics. I wouldn't consider Judo a subset of Jujutsu, nor would many other people. You clearly feel differently, but that's all a matter of opinion.
No, it's a matter of recognizing what it is, which is something you've shown to be unable to do in all respects.
Ah, wiki... Here's a fun fact.. when I accessed that page from my phone, it said "This article has issues"... from a PC it expands by saying it requires additional verification for some aspects. But let's get to the real problem here: You don't know what Jujutsu is, and that wiki article misses it as well, albeit it's a lot closer than you are. We'll deal with that in a bit.
So teaching breakfalling on mats as opposed to wooden floors, developing a belt system, removing dangerous techniques, applying scientific methods to techniques, etc. isn't a more modern approach?
No, it's not a more modern approach. Teaching breakfalls occurred on whatever surface the school used... what makes you think that Judo classes weren't held on wooden floors at times? Besides that, traditionally, you'd be training unarmed methods on matted floors (tatami), the wooden floored dojo are for weapon arts... so no, you're out there. The belt system wasn't anything to do with "modernizing", it was simply a practical answer to there being schools (in universities and educational institutions across Japan) all over the place, so when Kano went to teach, he wanted an immediately recognizable indication of the level of experience the student held if he'd never met them before. In most older systems, there would only be a single dojo, so the level of ability of each student would be known by the instructor already. The removal of "dangerous techniques" also isn't anything to do with "modernizing", it's to do with altering the art to suit a new context (teaching kids in schools, far more than anything to do with competition, for the record). And, as for applying scientific methods to techniques? Seriously old-school, mate. Kashima Shinryu has used such ideas since the mid 16th Century, and they're hardly alone.
The point was that classical Jujutsu isn't evolving in that way. Hence why its a "dead" art.
And my point is "how would you know?" To take Kashima Shinryu as an example again, the Jujutsu syllabus has been altered/restructured with each successive generation over at least the last 3... and a number of times prior to that. Araki Ryu has a long-standing tradition of pressure testing everything they do, altering, or even dropping any part of any method, even whole kata, if they don't "work". That art goes back to the beginning of the 17th Century. One of the best regarded modern combative teachers around, an absolute go-to guy for understanding real violence, is Rory Miller... who is trained in Sosuishi Ryu, a banpa ryu (off-shoot system) of Takenouchi Ryu. Again, seriously old school here... and if you think that Rory Miller is wasting his time with stuff that doesn't have any value, you're seriously out of your mind, and completely out of your depth.
Judo supplanted Jujutsu because by Kano's time Jujutsu was out of favor to most of the Japanese people.
Judo supplanted nothing. There was a backlash against anything seen to be related to the samurai after the Meiji Restoration of 1868, but there was no public school system teaching Jujutsu. Individual police areas would pick their own approach, but after the Meiji Restoration, there was a push to make things uniform, which is where the police tournaments came into it.
To this day, Jujutsu is rare in Japan, and if you ask someone to point you to a Jujutsu school, you're more than likely going to be directed to a Bjj school instead.
No, you're not. You'd more likely get a quizzical look, and be asked if you mean Judo or Aikido...
You can tell them whatever you like. The fact of the matter is that classical Jujutsu is rare in the country of its origin. That makes all classical Jj schools outside of Japan highly suspect. If someone wanted to learn Japanese JJ, I'd point them towards a Judo school without hesitation. That at least insures that the prospective student is learning something genuine.
Right, let's deal with this idea of "Jujutsu is rare in Japan". When you're looking at the older systems, in most cases each system would have a single dojo. There was no single art called "Jujutsu", so saying that "Jujutsu is rare" is just missing the point in the first place... it'd be like saying that "East LA High School" is rare... but High Schools, well, aren't. I can list dozens, if not hundreds of genuine Jujutsu schools in Japan, not to mention what's found in other schools, or the fact that there are more modern, larger organizations that offer genuine Jujutsu (and Jujutsu related) systems around the world... seriously, you're way out of your depth here. Suggesting Judo is fine, of course... you'll find that many classical practitioners have some exposure or experience in Judo as well (if they're Japanese, they did it in school), but your reasoning is way off base. Oh, and the word is "ensure", not "insure"... one means "to make certain", the other is "to provide financial compensation for loss".
