Origin
Meaning and origin of Uchida
The surname UCHIDA is of Japanese origin, originating in the 8th century during the Nara period. It is derived from the word "uchi," meaning "inside" or "within," and "da," which was an old nobility title. The name likely referred to someone who lived within a certain estate or manor.
UCHIDA is a locational surname, indicating that the first bearers of this name came from a specific place, likely a village or town called Uchida. The earliest recorded instances of the name can be found in historical records from the Heian period, which lasted from 794 to 1185 AD.
In the 12th century, the Uchida clan was a prominent samurai family that served under the Minamoto clan during the Genpei War. Uchida Ieyoshi (1154-1184) was a notable samurai who fought alongside Minamoto no Yoritomo and played a crucial role in establishing the Kamakura Shogunate.
During the Muromachi period (1336-1573), the Uchida clan continued to hold significant influence in various regions of Japan. Uchida Nobuyoshi (1535-1615) was a renowned daimyo (feudal lord) who served under Toyotomi Hideyoshi and played a vital role in the reunification of Japan during the late 16th century.
In the Edo period (1603-1868), the Uchida family produced several prominent scholars and intellectuals. Uchida Masao (1629-1711) was a renowned Confucian scholar who served as a tutor to the Tokugawa Shogunate. Uchida Gankyu (1763-1839) was a renowned scholar of Chinese literature and philosophy.
Another notable figure with the UCHIDA surname was Uchida Hyakken (1828-1893), a prominent sculptor and artist during the late Edo and early Meiji periods. His works played a significant role in the transition from traditional Japanese art to more modern styles influenced by Western techniques.

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. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Uchida surname at the time of the 2020 Census, not any inherent property of the name itself.
