Kappamaki

Kappamaki (Japanese: かっぱ巻き), cucumber sushi roll, is a norimaki (seaweed roll) with cucumber core. It is a typical thin sushi roll along with dried gourd rolls and tekka (thunnus sashimi) rolls. The name "Kappa" is thought to refer to the Japanese monster kappa, but there are various theories as to the origin of this name (see below).
