Due to its large size, it is called mehari-zushi, meaning, "so big that your eyes are attached.
" There is another theory that the takana is so hot that your eyes pop out, or you have to be on the look out so that the rice ball does not fall apart.
It developed from bentos (lunches) people brought while they worked in the mountains.
There is also zushi using shiroita-konbu (kelp with its surface scraped off) or yuba (dried bean curd).
There are so many kinds of zushi, it is no wonder they call it the land of zushi.
