Kurō

Kurō is a Japanese masculine given name typically written with the kanji characters ku (九) meaning "nine" and rō (郎) meaning "son". This name was traditionally used for the ninth son in a family, following a naming convention where numerals were combined with the element rō to indicate birth order. Other kanji combinations are also possible, leading to different meanings, such as characters meaning "black" (黒) or "toil" (労) with rō.

The naming practice using numbers in Japanese masculine names has historical roots, particularly among samurai families and commoners during the Edo period. Sibling sons were often distinguished by such names—Ichirō (first son), Jirō (second son), Saburō (third son), and so on. Kurō, meaning "ninth son," reflects this tradition.

Related variant forms include Kuro and Kurou, which use alternative romanizations or elongations. In modern usage, Kurō has declined in popularity, partly because families are typically smaller, but it remains as a traditional or character name.
