Meaning & origin

Jiro is a Japanese name that follows the traditional system of birth-order naming, where specific suffixes denote the child's position in the family. The name has been used in the United States since at least 1913, with its peak in 1918, when Japanese immigration to the mainland was at a high. Since 2022, the name has been in decline, reflecting broader naming trends away from traditional Japanese birth-order names among Japanese-American families. Despite its rarity, Jiro offers a strong cultural heritage and straightforward pronunciation.

Jiro is a Japanese masculine name typically given to a second son. It combines the kanji for 'two' (二, ji) and 'son' (郎, rō). The name follows the traditional Japanese naming convention for birth order, with Ichiro for first son, Jiro for second, Saburo for third, and so on.
