Ichiro is a Japanese name derived from "一" (ichi) meaning 'one' and "郎" (ro) meaning 'son', translating to 'first son'. It holds historical significance, as seen in figures like Ichirō Yamada, a renowned Edo period poet, and Ichiro Soga, a brave samurai. Today, it's popular among Japanese families, often chosen for first-born sons, and is sometimes used unisex due to its neutral meaning.
