Master Black Belt
My brother's Shotokan teacher studied with the Funakoshis in Japan after WWII, and my understanding is that 5th Dan was it; as high as you could go. There were no higher ranks until the 60's, likely in response to higher ranks being awarded in other styles (a 7th Dan has to better than a 5th Dan, right?). My brother's teacher actually split with the JKA when ranks above 5th Dan were approved and awarded, as he had received his 5th from one of Funakoshi Sensei's sons and thought a 6th Dan was a sacriledge in Shotokan. So, a 4th Dan in the 40's and 50's could very easily be seen as far more difficult to attain than a 4th Dan currently is in Shotokan or TKD. (I don't mean to disparage in any way any current students of Dan rank in Shotokan or TKD, just to point out what was the highest available rank during Funakoshi Sensei's time). And as you all likely know already, Funakoshi Sensei did not like people describing their rank as anything other than Black Belt when they were above Shodan, as he saw karate as an art, not a competition. If you were told people you were Sandan, you might have been seen as rather shallow by Funakoshi Sensei, so that was generally avoided.
