I salute you for at least acknowledging that there were some Black people in Japan at the time, a concession many are unwilling to make. I also pointed out that the places they would have been are among the places shown in the show, within the Christian delegation and part of the Black Ship crew for example. I wouldn't expect to see random people in rural Japan but much of the series is set in Osaka, one of the main cultural and economic centers at the time where again, they existed.
Maybe I was influenced by another story I was writing about comic book history which initially excluded Black people, not only from fictional places like Paradise Island, Metropolis, and Gotham City, but in New York as well. There were Black people in the very settings shown in Shogun, I don't think it unreasonable to include them.
It isn't bigoted to not include Black people in every story. In a story with the scope and scale of this one, it just might be bigoted to exclude them. In this venue I've received criticism which includes you suggesting Black people have little history and culture of their own (while certain states increase their efforts to change and erase it). On X I'm getting called ni**er and more so I kind of think that's bigoted too. Thanks again for acknowledging their presence, something the show does not.
