@G0 DVL,
I definitely agree that Japanese people excel at making mashups. In fact, they create so many incredible mashups that I sit back and wonder how we'll ever be able to tell which ones are worth covering. As an outsider, it almost seems like every thing that exists has been remixed beyond belief in Japan.
It becomes difficult to research memes that are popular amongst Japanese-speakers but not popular with English-speakers.
The more information you can share about each meme, the better. The problem isn't "too much Japan." The problem for me is my own lack of knowledge about Japanese culture online. For English-language memes that we're not familiar with, it's not too hard to research why they became popular. With foreign-languages, we kind of have to depend on the knowlege of our members.
For the most part, your entries will be Confirmed more quickly if you properly embed videos into your meme entries, and try to explain them using as much of Yatta's 6-points as you can.
Yatta's 6 points of analysis:
1) Viral Spread: search results, social media mentions, forum posts, route of spread.
2) Point of Origin: Find out where the meme first appeared and provide proof that it spread beyond its original subculture.
3) Derivatives: Existing volume of spoofs, mashups, remixes, parodies, recontextualizations, and re-enactments. Is it mutating?
4) Appearance in Memetic Hubs: Websites and communities that have been made famous for spreading and culturing memes.
5) Organic / Forced Memes: Was the meme spread peer to peer or was it astroturfed? Even astroturfed phenomena can become memes.
6) Spin-offs / Sub-memes: Many memes spawn entire trees of sub-memes.
