Akō's salted rice crackers are a specialty of Akō City in Hyōgo Prefecture, known for using sodium chloride salt that contains magnesium chloride, harvested from the Seto Inland Sea. Even before the widespread adoption of ion-exchange membrane salt production using vacuum evaporation tanks, Akō's salt was highly regarded for its quality during the era when salt pans and traditional boiling methods were employed. The salted rice crackers made with this salt offer a simple yet savory flavor, with a gentle saltiness and a toasty aroma.
