- "An armor is nothing but iron, leather, and silk. It can be replaced, but the man who wears the armor is..."
- —Ichiro Yamashiro to Ray Palmer[src]
Ichiro Yamashiro is the father of Masako Yamashiro and the late Oda Yamashiro. He assisted the time travelers known as the Legends, healing Nate Heywood and outfitting Ray Palmer in a suit of Samurai armor that once belonged to his son, Oda. Imparting words of wisdom on Ray, he later revealed that he, along with his daughter, they are a part of the Yamashiro family to the Legends.
Ichiro healed Nate Heywood when he traveled back in time and also inspired Ray Palmer to continue on his quest, despite losing the A.T.O.M. Exosuit. Although he inspired Ray to think more of a man who wears, then the armor itself, he also said that nobody should be ridiculous in thinking that they can stand against the Shogun without any armor. Ichiro gave his son's armor to Ray, hoping that it would serve him in battle. When Ray returned the armor, as it served its purpose, he asked Ichiro what his family's surname was, it was revealed that they are the ancestors of Maseo Yamashiro.
Ichiro was a wise, knowledgeable village doctor, who was, despite fearing for his family, ready to help a gaijin such as Nate Heywood heal his wounds. When faced with a possible destruction of his hometown by Tokugawa Iemitsu, Ichiro appeared accepting of either development of his fate, whether the Legends manage to save the hometown and avenge his son, or die trying. Seeing that Ray Palmer was distraught after losing his armor and being forced to destroy it, Ichiro imparted him with words of wisdom regarding armor being less important than the men that wear it. Despite that, he was pragmatic enough to know that nobody would be able to fight against Iemitsu without any armor.
