That they are, but dammit, they've gotta come from SOMEWHERE. I usually don't think too deep about that, because if I do I start asking myself "Why are people who are clearly not of japanese descent given japanese names when they die? Or, if they are all people who died in Japan and thus goes to the Japanese afterlife, why oh why is there a black man in there who died for over a hundred years ago?" It's... kind of too much for me to swallow.
