I'm not sure if I understand this secret. Does OP mean Japanese artists within a Western fandom or do they mean from the Japanese fandom? If it's the latter then I think your secret is stupid. One look at Pixiv makes it obvious that there are tons of Japanese artists who are neglected. And it makes sense that only the really good stuff would be brought over to the Western fandom.

Basically it just sounds like you're making excuses for yourself...
