Gon'ichirō

Gon'ichirō is a traditional Japanese male name. The 'Gon' (五) typically means 'five' and is often used to denote birth order, specifically the fifth son. The 'ichirō' (一郎) component is a common suffix in Japanese male names, meaning 'first son' or 'eldest son', but when combined with a number like 'Gon', it reinforces the idea of a numbered son. Names incorporating numbers like 'ichirō', 'jirō' (second son), 'saburō' (third son), 'shirō' (fourth son), and 'gorō' (fifth son) were historically very common in Japan to indicate birth order within a family.

While 'gorō' explicitly means 'fifth son', 'Gon'ichirō' also carries the meaning of 'fifth son' due to the 'Gon' (five) prefix. The use of 'ichirō' in this context is more about the 'son' part of the meaning, with 'Gon' specifying the order. These types of names, while still understood, are less common in modern Japan as naming conventions have diversified.
