Explanation:

[STC001614] Hidekazu Tojo, a sushi chef, learned culinary arts in Japan, but after moving from Osaka to Vancouver, Canada, in 1971, he popularized sushi and the now-famous California roll. The chef adapted the fundamentals of sushi from Japan for Western palates that weren’t accustomed to eating raw fish. In order to cover up the seaweed, the sushi rice was also flipped from the outside to the inside. According to Tojo, the term “California Roll” was coined by the out-of-towners, many of whom were from Los Angeles, who gave the roll raving reviews and helped fuel its explosive growth in the late 1970s. While several chefs in Los Angeles and elsewhere claim to have created variants of the roll, Tojo was honored by the Japanese government in 2016 for both creating the dish and his work promoting Japanese cuisine.
