Sushi having the same name does exist in Kansai such as Osaka and the whole eastern Japan area (as explained later), but what characterizes Okayama barazushi is that its topping ingredients overwhelmingly exceeds those of the Osaka version in kind, size of each piece, volume and manner in which they are displayed.
大阪などの関西・東日本一帯でも同様の名称の寿司（後述）があるが、乗せる具材の品目数・大きさ・量・盛りつけの豪華さなどが大阪の物よりも圧倒的に多いのが特徴。
