Senior Master
in another thread you and I discussed my suggestion that the dan rankings be eliminated and only two black belt ranks ought to exist: non-teacher, and teacher. Beyond that, there would be no higher promotions. This is a perfect example of what my idea is intended to eliminate. I know that nobody will adopt it, at least not on a wide scale use. But this is why I came up with it.
In the early days of karate, there were just a few ranks like you describe. While on mainland Japan, the kyu and dan colored and black belt system of Judo master Kano was adopted by Shotokan in the 1920's (the Japanese love to be organized and standardized), this did not catch on in Okinawa (more independent types) until post World War II. Prior to that, the experts had only 4 instructor ranks: sensei, renshi, kyoshi, and hanshi (these titles are still with us today.)
The difference between then and now is that these titles, as well as 8th, 9th, and 10th degree black, had real street cred back then. Why? Because they were not given out by some other guy who promoted himself, a buddy, or some guy who charged money for them. They were given out by a board of recognized and unimpeachable masters who stood at the apex of the karate world. Guys who studied from the legendary godfathers of karate, like Bushi Matsumura, Higashionna Kanryo, Kyan Chotoku, and Itosu Anko. Their students like Miyagi, Funakoshi, Chibana and Mabuni, among others, were those that made up the board.
While the organization, name, and members changed over the years, its function and credibility did not. So the judges were not like Judge Judy (a reality TV judge), but more like the U.S. Supreme Court.
Note that these board members represented multiple Okinawan styles. So there was no hegemony. To become a master, you had to be accepted by the other masters (from competing styles.) Zenryo Shimabukuro, Hohan Soken, Chojun Miyagi and Tatsuo Shimabuku (as well as his younger brother, Eizo) received their highest ranks in this way. You were accepted by your peers.
This system is still, more or less (mostly less but still credible), in place today in Okinawa and Japan. In the USA and no doubt elsewhere, there are some organizations, especially those with strong ties to Okinawa/Japan, that carry on this tradition of credibility and authenticity. But for the most part, self-promotion and bogus masters are running amok and give karate a bad reputation.
So, going back to that original thread of "What is a black belt", I think we can set some objective standards, a fairly high bar, to judge quality from crap. Whether the pretenders and uninformed like it or not.
