Yoshiro is a unisex given name of Japanese origin, derived from the kanji characters 義 ('justice' or 'righteousness') and 善 ('goodness'). This name has been used for both boys and girls in Japan but is more commonly associated with males due to its historical usage. The name's popularity peaked during the mid-20th century, particularly in the post-World War II era, but it remains a less common choice today. In Japanese culture, Yoshiro is often considered an auspicious name due to its positive connotations of justice and goodness.
"The name Yoshiro was popular in the early to mid-1920s with a peak of six births each year in 1921 and 1922, followed by five births annually until 1925. It then appeared less frequently, with another spike of five births in 1929."
