Meaning & origin
Kotaro is a Japanese male name that follows the traditional pattern of combining an element with 'taro', meaning eldest son. First recorded in U.S. data in 1919, it reflects Japanese naming conventions that prioritize birth order. The name saw a peak in usage in 2010, but overall it has remained stable with limited popularity. Its meaning depends on the kanji, so it can signify either 'small' or 'thick' eldest son, adding a layer of personal significance for families. Top states for the name are not listed, indicating no strong regional concentration. For parents drawn to short, authentic Japanese names with a clear cultural heritage, Kotaro offers a straightforward option with deep roots in Japanese tradition.
Kotaro is a common Japanese male name composed of two elements: ko (小) meaning 'small, little' or (太) meaning 'thick, big', and taro (太郎) meaning 'eldest son'. The name follows a traditional Japanese naming pattern where taro is often used for the firstborn son. It has been in use since at least the early 20th century and remains familiar in Japan, though it is less common today.
