Most of my townies/randomly generated sims have Japanese names too for some reason. It wouldn't bother me if I could at least pretend the game is in Japan. But the thing is, it's just the same names over and over. In my current save I have already met THREE kids named Mariko and TWO named Ayaka. And basically those are the only kids in town, in case you wondered. Yay. I'm pretty sure most people have different names in Asia too, you know, it's not like an American or a European "thing". Most languages have hundreds and hundreds of names. This is just sad.
I don't get me started on the amount of choice you have with the CAS name generator...
