In the early 2000s, Yoshinoya triggered a discount war in Japan along with other chains such as McDonald's, by introducing a regular gyudon dish for 280 yen. However, in late 2001 the mad cow incident critically damaged the sales on Yoshinoya's beef menu.
Yoshinoya also has an ambitious plan to expand its chain overseas. [1] [1]
