Mōri Motonari
In July 1562 at the First Siege of Toda Castle, Mōri Motonari ordered Hayashi Narinaga to go as a messenger to Honjō Etchū-no-kami Tsunemitsu (本城常光). Honjō Tsunemitsu held Yamabuki Castle (山吹城) in Iwami Province and was originally a vassal of the Amago clan, but defected to Mōri Motonari in 1563. Yamabuki Castle was strategically important for control of the Iwami Ginzan Silver Mine.&lt;br&gt; Two years later in April, 1564, Narinaga attended the Second Siege of Toda Castle.
