Neta are typically fish such as salmon, tuna or other seafood. Certain toppings are typically bound to the rice with a thin strip of nori, most commonly octopus (tako), freshwater eel (unagi), sea eel (anago), squid (ika), and sweet egg (tamago).
Oshizushi = Pressed Sushi
Also known as hako-zushi, box sushi, is a pressed sushi from the Kansai region, a favorite and specialty of Osaka. A block-shaped piece is formed using a wooden mold, called an oshibako. The chef lines the bottom of the oshibako with the toppings, covers them with sushi rice, and then presses the lid of the mold down to create a compact, rectilinear block. The block is removed from the mold and then cut into bite-sized pieces. Particularly famous is battera, pressed mackerel sushi) or saba zushi. In oshizushi, all the ingredients are either cooked or cured and raw fish is never used.
