The whole point of banning relationships between close family members is that children born out of such relationships have a far higher chance of inheriting alleles that are the cause of genetic illnesses. However in Japan, due to the long isolation and numerous marriages between close family members, the carriers of such diseases gradually died out to the point where marriages between Japanese cousins have a far lower chance of giving birth to children with genetic illnesses than the cousins within other cultures would. If the consequences of relationships between cousins are not really severe, then why ban it? Thus our concept of incest differs greatly from the concept in Japan and just because it differs from your concept doesn't mean that it is wrong. If you can't get over your prejudice, then that is your own problem.
