Find out about recommended ways to prepare these fish and shellfish, which are oftentimes unique to the regions where they are most commonly caught in Japan.

Features and Preparation of Salmon

Salmon start their lives in rivers, migrate to the sea for several years, and then return to the river where they came from to spawn. They are often thought to be red-fleshed because of the color of the meat, but they are actually categorized as a white-fleshed fish. Salmon feed on shrimp and crabs, and the color of these foods cause the flesh to become reddish pink.

There are many different types of salmon. Let's take a look at the features of the main types.

Chum salmon

The most common type of salmon in Japan is the chum salmon. It is caught in the Sea of Okhotsk north of Hokkaido, the Sea of Japan near the Hokuriku region, and the North Pacific Ocean near northern Japan. It prefers cold waters and is in season from autumn through winter. It is very tasty and fatty during this season.

Sockeye Salmon

Sockeye salmon has a reddish flesh and is very popular in Japan. However, most of it is imported from Alaska and Canada. The fat content is very high, making it a delicious choice.

Coho salmon

Coho salmon is a salmon that looks similar to chum salmon. It is characterized by the silvery color of its belly and is often imported from Chile to Japan. It is also very fatty and delicious when smoked.

Pink salmon

The pink salmon is often caught along the coast of the Sea of Okhotsk. It is slightly less reddish than other types of salmon. It is characterized by its low fat content, causing the flesh to easily break up. Because it is one of the most abundant salmon species, its price is low. It is sometimes processed into canned products.

Salmon is very tasty when eaten raw as sashimi or sushi. It is also popular as meuniere, a preparation method where the fish is to be filleted, dusted with flour and baked in butter, or simply grilled with salt. It is also sometimes fried.
