The Japanese language may not be "esoteric", but this article certainly is obscure. It's based on an English languange phenomenon, and so one would not expect many first-language Japanese editors to have interest. In any case, unsourced challenged material does NOT get the benefit of the doubt. It's up to you to prove that it is worthy of staying. Where are all those fluent Japanese editors defending this translation? So far, everyone has been quick to defend the *idea* of the material, but no one has come by and defended the actual content.
