Yoichiro (Japanese: Yōichirō) is a masculine given name built from yō + ichi + rō. The element yō can be written with kanji such as 陽 “sunny,” 洋 “ocean/Western,” or 曜 “radiance,” while ichi (一) means “one,” and rō (郎) denotes “son; young man” (sometimes 朗 “bright” is used).

Overall meaning: a positive yō quality combined with “first son,” signaling brightness, breadth, or steadiness in an eldest child.
