Gauldar, you're correct. Promotions in judo are earn via two avenues: success in competition, and advancement of the art of judo. If I remember correctly, the Kodokan does not promote beyond the 5th dan for competitive achievements, such as earning a medal at the Olympics, World Games, etc. My sensei, a 7th dan, excelled at kata at the international level. In the later part of his life, he has trained judoka to compete at the international level, and acted as a consultant to the International Judo Federation and the International Olympic Committee. Despite his success, he will not likely earn another promotion in his lifetime, because of the sheer difficultly ramp at the highest echelons of the art. Keiko Fukuda's promotion is an acknowledgement of lifetime of dedication to Kodokan Judo, the lives she has touched through her instruction, and wealth of knowledge she represents.
