Rice has been cultivated in the Tagajo environs since ancient times. In a return to these roots, rice producers today are cultivating ancient rice, known as kodaimai, thought to be similar to the earliest species of rice grown in Japan. This ancient variety, with its beautiful purple hue, has a crackly texture and satisfying chewiness. In addition, it is rich in minerals, vitamins, anthocyanin—a type of polyphenol—and other nutrients, making it popular among people who care about beauty and health. Shiro no Murasaki is the general brand name for gourmet products made using ancient rice, a specialty of the historic city of Tagajo.
Today, restaurants and cafés in Tagajo City serve bread, noodle dishes, and sweets made with ancient rice. In addition, supermarkets and farm stands sell sake and packs of ancient rice. Each product is creatively crafted to highlight the history of Tagajo and the delicious flavor of ancient rice.
