How long does it take to get a10th Dan in Judo?Can I get a link to the time in grade per Dan for Judo?What about learning the67 Judo Throws?

minimum age is If I remember correctly is72, and over 55 years of training.

Most people are dead when they received it. the number of 10th dan's in judo can be counted on one hand.

Its more then just technique at this point its about what you have given back and contributed to judo on an international level. 

@Bon There was an organization called fajko, back in the 1800's they set the minimum ages and minimum time frames as well as many of the standards used by todays organizations 

There is no such thing as a set timeline of how much time per grade or dan. Martial art is not a video gram where you level up after a certain amount of points or time. Everyone progresses at their own pace.
