History of National Dashi Day
Dashi itself has a rich history dating back over 800 years to Japan’s Heian period. This simple yet profound broth was originally created by simmering kombu and dried fish to extract their natural umami flavors. During the Edo period (1603-1868), dashi became firmly established as the cornerstone of Japanese cooking, appearing in literature and cookbooks of the time.
The Kansai region (Kyoto & Osaka) played a significant role in dashi’s development, while regional variations emerged throughout Japan. In the Kyushu region, “ago dashi” made from dried flying fish became popular among common people by the mid-Edo period.
The scientific understanding of dashi’s appeal came when Japanese researcher Kikunae Ikeda identified glutamate as the source of dashi’s distinctive savory taste, coining the term “umami” – now recognized globally as the fifth basic taste alongside sweet, sour, salty, and bitter.
