What is Ma-Iwashi?
These are in peak season at the moment, and are referred to as “autumn sardines” or “true sardines” when caught during September to October.
Ma-Iwashi, or Japanese sardine, is a type of bluefish renowned in Japan for its distinctive flavor and nutritional value. Easily recognized by its bright silver line running along its body, Ma-Iwashi has a tender, juicy texture that becomes especially rich in autumn when the fish develops a balanced, flavorful fat layer. During this season, the sardine’s meat is celebrated for its deep umami, heightened by the natural oils it accumulates.
High in essential nutrients like omega-3 fatty acids (DHA and EPA), vitamin D, and calcium, Ma-Iwashi has been cherished as a seasonal delicacy and a nutritional powerhouse in Japan for centuries, offering both a satisfying taste and numerous health benefits.
