Kentarou is Japanese in Origin.

Kentarou is a Japanese masculine given name built from kanji elements, most commonly written 健太郎. The long final vowel may be romanized as Kentarō or Kentaro; Kentarou reflects the kana spelling with ou. The -tarō/-rō suffix was a classic male name ending meaning “son,” once favored for first-born boys, though not tied to birth order today; it saw strong use from the late Edo through Shōwa periods. Diminutives and variants include Kenta and Ken, while less common spellings such as 謙太郎 or 憲太郎 appear.

Meaning varies by characters: 健 (healthy, robust), 謙 (modest), 憲 (law, constitution), 兼 (combine); paired with 太 (big, great) and 郎 (son, gentleman). Thus 健太郎 is often glossed “healthy, big son,” and 謙太郎 “modest eldest son.” The name remains familiar through cultural figures like manga artist Kentaro Miura and actor Kentarō Sakaguchi, giving it a timeless, traditional yet approachable feel.
