Origin
The surname UCHINO has its origins in Japan, with the earliest recorded instances dating back to the Muromachi period (1336-1573). The name is believed to have derived from the Japanese words "uchi" meaning "inside" and "no" meaning "of", potentially referring to someone who lived within a particular area or settlement.
One of the earliest documented references to the UCHINO name can be found in the records of the Tokugawa Shogunate, which ruled Japan from 1603 to 1868. These records mention a samurai warrior named Uchino Masahiro, who served under the famous Tokugawa Ieyasu during the late 16th century.
During the Edo period (1603-1868), the UCHINO name was particularly prevalent in the Kyoto region of Japan. Historical records from this time indicate that there was a prominent family of merchants and artisans who bore the UCHINO surname and were renowned for their expertise in traditional Japanese crafts, such as pottery and woodworking.
In the late 19th century, a notable figure with the UCHINO surname emerged – Uchino Kumazo (1860-1925), a politician and diplomat who played a significant role in the modernization of Japan during the Meiji Restoration. He served as the Minister of Agriculture and Commerce and was instrumental in the establishment of Japan's first modern postal system.
Another individual of historical significance was Uchino Tsunekichi (1877-1952), a renowned Japanese architect who designed several iconic buildings in Tokyo, including the Nippon Yusen Kaisha Building and the former headquarters of the Dai-ichi Life Insurance Company.
The UCHINO name has also been associated with literary figures, such as Uchino Kenji (1914-1971), a celebrated poet and translator who was renowned for his translations of works by Walt Whitman and other Western poets into Japanese.
While the UCHINO surname has its roots in Japan, it has since spread to other parts of the world due to emigration and globalization. However, its origins can be traced back to the rich cultural heritage of Japan, where it has been a part of the nation's history for centuries.
Demographics
Among Census respondents with the surname Uchino, the largest self-reported group is Asian/Pacific Islander at 86.3%. The next largest groups are Hispanic (8.5%) and White (3.4%).
The bar chart below shows how Uchino bearers described their own race and ethnicity on the 2020 Census form. 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 Uchino surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
