Matt Thorn sez: no!

The Japanese are not Other within their own borders, and therefore drawn (or painted or sculpted) representations of, by and for Japanese do not, as a rule, include stereotyped racial markers. A circle with two dots for eyes and a line for a mouth is, by default, Japanese.

Yes. Similarly, when a white person looks at a henohenomoheji face, they usually don't see a Japanese person there, despite the obvious and extreme Japaneseness of its provenance.

On the other hand, a hemamushiyo-nyūdō does look like a specifically Asian sage, at least to me... but I'm pretty sure that's because of the robe.

In other news, commenting has been adjusted so that links will work... I think.
