Origin
Meaning and origin of Uyematsu
The surname Uyematsu originates from Japan and can be traced back to the early 15th century. It is believed to have originated in the Kyoto region, where it was likely derived from a combination of the Japanese words "uye" (上), meaning "upper" or "superior," and "matsu" (松), meaning "pine tree."
During the Muromachi period (1336-1573), the name Uyematsu appeared in several historical records, notably in documents related to the samurai class and local administrative matters. One of the earliest recorded instances of the name can be found in a land registry from the year 1421, which mentions an individual named Uyematsu no Jiro.
In the late 16th century, the Uyematsu family established itself in the Shizuoka prefecture, where they were known for their involvement in the production of high-quality silk and silk-related goods. Several members of the family gained prominence during this time, including Uyematsu Masanobu (1548-1623), a skilled silk weaver and merchant.
Throughout the Edo period (1603-1868), the Uyematsu name continued to be associated with the silk trade, and they were recognized as one of the leading silk-producing families in the region. One notable figure from this era was Uyematsu Genroku (1676-1741), a renowned silk merchant who established trade routes connecting Shizuoka with other parts of Japan.
As the Meiji Restoration (1868-1912) ushered in a new era of modernization and industrialization, the Uyematsu family diversified their business interests. Uyematsu Yoshitaro (1836-1908) was a prominent figure during this time, contributing to the development of the textile industry and serving as a member of the local government council.
Another notable individual bearing the Uyematsu name was Uyematsu Sachiko (1892-1971), a pioneering educator who founded one of the first girls' schools in Shizuoka and advocated for women's education and empowerment.
Throughout its history, the Uyematsu name has been associated with various professions and industries, including silk production, textile manufacturing, education, and local governance. While its origins can be traced back to the 15th century in the Kyoto region, the name has left a lasting legacy in the Shizuoka prefecture, where it has been deeply woven into the cultural and economic fabric of the area for centuries.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers.
