What is the meaning of the name Keitarou ?

Keitarou is Japanese in Origin.

Keitarou is a masculine Japanese given name (けいたろう) built from kei + ta “great” + rō “son/young man.” Common spellings include 慶太郎 (joy/celebration + great + son), 敬太郎 (respect + great + son), and 啓太郎 (enlighten + great + son); the final element may also be 朗 “bright,” yielding forms like 慶太朗. Because meanings hinge on the chosen kanji, the name conveys virtues such as joyful fortune, respectful character, or enlightened strength, with -tarō historically associated with an eldest son.

Names ending in -tarō flourished from the Edo to early Shōwa eras, giving Keitarou a classic, steady feel in Japan today rather than trend-driven popularity. Romanization varies: Keitarō (with macron), Keitaro (simplified), and Keitarou (showing the long ō). Familiar shortenings include Kei or Taro. Related forms include Keita (dropping -rō) and Kentarō. The name appears in literature and popular media, reinforcing its traditional yet approachable tone.
