Soy sauce brewing is said to have been born out of the process used to make Kinzanji miso, which originated in the Kamakura era. The town of Yuasa in Wakayama is well-known as the birthplace of shoyu, or soy sauce, and is rich in history, a town where the somehow nostalgic streetscape merges with the blue ocean and mountains that surround it. In 2006, Yuasa was designated by the Japanese government as an Important Preservation District for Groups of Traditional Buildings.
