John F. Seems like very, very bad practice to use Douke as the main entry. By all means include a cross-reference, but to start following idiosyncratic usages for main references would mean unravelling thousands of references in Sensei's Library, the British Library, the US Congress Library and millions of other standard usages.
tchan001 If you can persuade the Nihon Kiin to change the English name for this person in their profile, by all means use the version you think is correct. Personally I prefer to follow the official version.
