What is Isaki?
Isaki is written using a few different character combinations, “鶏魚” (which translates literally as ‘chicken fish’), “伊佐木” and “伊佐幾”. Adult Isaki grows as long as 40 cm. You can find it on the coasts of Japan where there are warm currents. In most cases, fish lose their flavor during the spawning season, but isaki maintains its flavor even when carrying eggs, so it is available to eat during its summer spawning season.

There are fish other than Isaki that peak in Summer and have high fat content such as swordfish, conger eel, and unagi, but all of these fish have slender bodies such, so fish like Isaki is rare. As it has a large amount of fat, it is also rich in DHA and EPA, which can delay the progression of arteriosclerosis and prevent lifestyle-related diseases.
