Meaning & origin

Yasuo is a Japanese masculine name that has appeared sporadically in U.S. birth records since 1914, with its peak year being 1919. While it has never ranked among the top 1000 names, its usage trajectory has remained stable over the decades, with minimal fluctuation. The name carries a peaceful meaning, and its resemblance to the popular feminine name Yasmin sometimes causes confusion. Unlike more widely adopted Japanese names such as Yuki or Kenji, Yasuo has not seen a revival in recent years. Its rarity in the United States, where it is given to fewer than 1 in 1 million babies in 2025, makes it a distinctive choice for families seeking a name with Japanese heritage.

Yasuo is a Japanese masculine given name composed of elements that can be written with various kanji characters. The first element, yasu, often means 'peaceful' or 'calm' (安). The second element, o, can mean 'man' (男) or 'husband' (夫), or sometimes 'second son' (郎). The name has been in use since at least the early 20th century, with its peak recorded in 1919 according to U.S. Social Security data. It remains a recognizable Japanese name internationally.
