The salted roes of herring are also called a yellow diamond. The sushi is usually topped with dried bonito flakes and is called "Kazu no ko". This name is derived from "Kado no ko" which means herring roe. The ''Kado'' part is changed to ''Kazu'' which means numerous.
People used to ferment fish with rice for preservation before Edo style sushi appeared around 1716.
