Not really. Just because it's bad to reproduce with a close family member, doesn't necessarily mean we naturally find close family members unattractive. There's no evolution reason for that, anyway. It does kind of come naturally, but it's highly likely to be nurture, not nature. Consider Freud's work, where he hypothesises that a young boy goes through a phase where he is fixated on his mother, the Oedipus complex. If evolution insisted we find family members sexually repellent, then this phase of a boy's life makes no sense. Though at college, in psychology lessons I hypothesised that Freud was fucking weird and his childhood emotions were not common in boys of his age, and his work was his attempt to convince himself he wasn't weird. I basically psychoanalysed Freud in GSCE psychology.
I digress. People who are into incest are less likely to have offspring capable of reproduction, but that doesn't mean shit, because to argue that this is a product of evolution is to argue that someone who is into incest is that way due to genetics, rather than just being fucking weird.
As for why it's a thing in Japan, they're about as sexually weird as it gets for a culture. Individuals can obviously be way more depraved, but I challenge you to find a weirder population in this regard. It's all the more strange with them because in pretty much every other way they are socially perfect human beings, especially for such a large population.
The Germans are pretty fucking weird too, though as best I'm aware, they're not into shitting on their sisters.
