Ogata, Judan
I submit that Ogata's name above his character section should have "10-dan" replaced with the Japanese "Judan" for the reason that "Judan" is not a literal rank; it is the name of a title of which he is the current holder (for the duration of the series). His rank is 9-dan; there is no such thing as a 10-dan.   see http://senseis.xmp.net/?Judan, especially the sentence "Challenging for the title warrants a promotion to 7-dan, actually winning the title promotes to 8-dan, and finally winning the title twice gives an immediate 9-dan promotion." If it were a literal "10-dan" rank, then winning it wouldn't guarantee a promotion to 8-dan, would it? ) 72.84.200.91
