Sushi is originally Japanese, but the creative, colorful rolls found in American sushi restaurants are a distinctly American creation. Japanese sushi first came to the US in 1966, when Kawafuku opened in Los Angeles, California. However, it wasn't until the 1970s that sushi chefs began experimenting with ways to make rice and raw fish more appealing to American tastebuds. The result? California rolls, spicy tuna rolls, Philly rolls, Alaska rolls, and every kind of multicolored, fantastically named sushi roll found in American sushi restaurants.
