Check the citations on the Wikipedia article. They go in circles back to one, single source of questionable credibility. Then check the logs, they clearly show that this was a highly controversial article that was eventually locked without any real resolution. The fact that this Wikipedia article is now being cited as fact shows the power of propaganda.
The notion that a black man, or even any non-Japanese man could rise to the rank of Samurai is beyond preposterous to anyone even vaguely acquainted with Japanese history. The country is well-known for having an almost ridiculously ethno-nationalist culture well into the 20th century, and even today anyone of non-Japanese heritage moving to Japan will forever be regarded as a foreigner by the native population.
Would it have been interesting if there had been a real black Samurai, and would it have made for a good story? Sure, but there absolutely, definitely wasn't, so why would one claim that one existed instead of just making up a story and be honest about it? It may have something to do with the current cultural climate, where there's exists this Western phenomenon where one bends over backwards to insert people of some ethnicities into places and periods where they don't historically belong. It's the kind of fixation on ethnicity and superficial features that one used to consider a sure sign of racism.
(No, Cleopatra wasn't black, and neither was Anne Boleyn. It wouldn't really matter if they were, it's just that they simply weren't, just like Martin Luther King wasn't Italian, and Shaka kaSenzangakhona wasn't Irish. And while we're at it, Snow White got her name from the paleness of her skin, and the Little Mermaid is redheaded character from a Danish fairytale.)
