Thanks David. I could have gone my whole life without that description. ;-)

That said there may be some remote
place in Japan
that does use kani miso as neta. But it certainly is not mainstream.

You're right that it's not necessarily mainstream, but it's probably a lot
more ubiquitous than you think. For example, kani miso sushi (as gunkan
maki), is served at all of the Bikkuri Sushi restaurants in Tokyo. Bikkuri
Sushi is a kaiten (conveyor-belt) sushi chain with dozens of locations
throughout Tokyo. I've also seen it served at many other lower-end
sushi restaurants in Tokyo.
