The name derives from an image of a Jizo, the guardian spirit who looks over children, which the chef received from a Buddhist temple. The character for ‘sushi’ is an unusual choice, harking back to the fermented fish from which modern nigirizushi originated. The chef is deeply interested in literature and the classics. As snacks were not part of a sushi shop’s menu in the days of food stalls, the chef presents the range of toppings available before starting to form his sushi. Gizzard shad is moulded in the shape of the Edo-era Katsuyama hairstyle. In a relic of traditional practice, shrimp on sushi rice is paired with nori.
