Meaning & origin

Masayoshi entered U.S. Social Security records in 1914, its peak year, and has remained consistently rare since then, with a stable trajectory showing no resurgence. The name carries strong moral weight in Japanese culture, combining the kanji for 'correctness' and 'goodness' to evoke integrity. While not common in the United States, it reflects a meaningful and traditional choice for families seeking a name with ethical resonance.

Masayoshi is a Japanese masculine name formed from two kanji characters. The first element, masa (正), commonly means 'correct,' 'righteous,' or 'just.' The second element, yoshi (良/義), can mean 'good,' 'virtue,' or 'righteousness.' Combined, the name conveys ideals of moral uprightness. It has been used in Japan for centuries, often given to boys with the hope they embody fairness and integrity.
