Gojirō

Gojirō is a traditional Japanese male given name. The 'Go' (五) kanji means 'five', and '-jirō' (次郎) is a common suffix for male names, often indicating 'second son' or, more broadly, a male child. When combined, it traditionally referred to the fifth son in a family. This naming convention was historically prevalent in Japan, especially in larger families, to denote birth order.

While less common in modern Japan due to smaller family sizes, names incorporating birth order suffixes like -jirō, -ichirō (first son), -jirō (second son), -saburō (third son), and -shirō (fourth son) were once very widespread. The name Gojirō carries a sense of tradition and family lineage.
