Akami nigiri is a traditional type of nigiri sushi. It consists of hand-pressed sushi rice that's topped with slices of akami (red meat) tuna. There are also otoro (fatty tuna) nigiri sushi and chutoro (medium-fatty tuna) nigiri sushi varieties, and all of them are classified under maguro (tuna) nigiri sushi.

Akami includes tuna and bonito, and the meat gets its red color from the high content of myoglobin and hemoglobin, which is typical for migratory fish. The slices are on the thicker side and the focus is on tuna's sticky and firm texture. Akami nigiri sushi is usually served with pickled ginger (gari), soy sauce, and wasabi on the side.
