I don't understand where people are getting the idea that Russia/America is rare in Hetalia's Japanese fandom or only liked in the American. Sure, it's nowhere near as popular as in the west, where it's the most popular Russia pairing and second most popular America pairing (at least USUK deserves to be popular). But every artist on Pixiv I've seen who draws mostly Russia, draws Russia/America at some point.

And I hate Russia/America, I wish the J-fandom ignored it.
