In Japan, you can marry or have a relationship with your cousin. It's legal.

But it's disgusting if cousins are blood related 
In America too. It's legal to marry your cousin
But it has to be like 3rd or 4th cousins, enough so the bloodline is far enough apart unless you're in the south then them are hillbilly rules.
Yap in my cauntry its legal eather. Just why not
