Kotaro is Japanese in Origin.
Kotaro (commonly written as Kōtarō or Kotarou) is a Japanese masculine name built on the element Tarō (太郎 “eldest son”) combined with a first kanji usually read Kō or Ko. Meanings depend on the chosen characters: 光太郎 “light,” 幸太郎 “good fortune,” 孝太郎 “filial piety,” 航太郎 “navigation,” or 小太郎 “little Tarō.” Pronounced koh-TAH-roh; long vowels often marked with a macron (Kōtarō) or spelled -ou.
As one of Japan’s classic -tarō names, Kotaro has appeared since medieval times; the famed ninja leader Fūma Kotarō anchors its early visibility. The name stayed common through Meiji and Shōwa and today feels traditional yet lively. Common romanizations include Kotaro and Kōtarō; short forms are Kō or Taro. Notable bearers include novelist Isaka Kōtarō, actor Koizumi Kōtarō, and guitarist Oshio Kotaro. Overall sense: “(virtue/light/fortune) of the eldest son,” though modern use is not limited by birth order.
