Job's Tears (Coix lacryma-jobi), Coixseed, adlay, or adlai, is a tall grain-bearing tropical plant
of the family Poaceae (grass family) native to East Asia. Throughout East Asia, Job's Tears
are available in dried form and cooked as a grain. The grains are generally spherical, with a
groove on one end, and polished white in color, though in Japan unpolished yuuki hatomugi.
