Japanese Sushi Puzzle

Sushi (すし, 寿司, 鮨, 鮓, 寿斗, 寿し, 壽司?) is a Japanese food consisting of cooked vinegared rice (shari [しゃり]) combined with other ingredients (neta [寿司ネタ]), usually raw fish or other seafood. Neta and forms of sushi presentation vary widely, but the ingredient which all sushi have in common is shari. Shari is also referred to as sushi-meshi (寿司飯, "sushi rice").

Raw meat (usually but not necessarily seafood) sliced and served by itself is sashimi.
