Cucumber rolls are called kappamaki in Japan. It is one of the most popular sushi rolls and is easy to make, with just three ingredients–nori (dried seaweed), sushi rice, and cucumber. As there is no fish included, this roll is also perfect for vegetarians.

The word kappa doesn't actually mean cucumber in Japanese (that is kyuuri); it refers to a demon or imp figure from Japanese traditional folklore. The word kappa is a combination of words meaning "river" and "child" and is related to water. Somehow, a kappa is associated with cucumbers, hence the name of this sushi roll. Interestingly, no other Japanese cucumber dishes are called kappa.

This recipe calls for Japanese cucumbers, which are long, slender, and thin-skinned. They do not have seeds nor any bitter taste and are therefore easy to handle and a pleasure to eat. If you cannot find Japanese cucumbers, mini Persian or English cucumbers are good substitutes.
