Japanese Millet🌾
Echinochloa esculenta
ヒエ
An annual in the grass family. Along with foxtail millet (awa) and proso millet (kibi), one of Japan's oldest cereals, cultivated since the Jōmon period. Domesticated from the wild barnyard grass (E. crus-galli). Important as a staple in cold regions and Tōhoku where rice was difficult to grow; declined after the Meiji era as rice production expanded. Now revalued as an allergen-friendly grain and in traditional foods (hie-mochi, hie-zōsui).
