The intensity of the japanese character is, in large part, i think, a factor in this. The late nineteenth early twentieth century's one of the high water marks of global racism and the pseudo science of it. And we'll talk about race, ecause it matters in a story that's very multi racial in an era that's very racest. But by the way, full disclaimers are here. There's going to be a lot of race talk in this programme, not because it matters to me or because i think it's important, but because it matter to the people in this story. It's carrots and sticks.
