In order to survive in the struggle for lands, many samurais in the Sengoku period preferred to use a picture of Myoga as their symbol on the battlefield, because the pronunciation of the term Myoga is the same as that of the term (冥加), which means luck.
領地のために命を張った戦国武士などは、戦闘で命が残る「冥加」にかけて、「茗荷」の紋を好んで使用した。
