Kyūtarō

Kyūtarō is a traditional Japanese male name. The 'Kyū' (九) character means 'nine', and 'tarō' (太郎) is a common suffix for male names, often meaning 'eldest son' or simply 'son'. When combined, it traditionally designated the ninth son in a family. This naming convention was historically prevalent in Japan, especially in larger families, to indicate birth order.

While the direct meaning points to birth order, the 'tarō' suffix itself carries connotations of strength and masculinity. Names ending in -tarō were very common in feudal Japan and continue to be used, though less frequently for birth order designation in modern times. The name reflects a cultural practice of naming children based on their position within the family.
