In December 2005, Japan agreed to remove the restriction on importing beef from the United States. A letter to customers was then put up in restaurants, promising that the beef bowl would return in a few months. In January 2006, imports stopped again because inspectors found banned cattle parts in a veal shipment from the United States. In June 2006, Japan lifted the ban on imports again, and on July 31, 2006, Yoshinoya reposted the letter promising to resume serving the beef bowl in about two months.
