Origin
The surname SUENAGA is of Japanese origin, dating back to the Kamakura period (1185-1333 CE) in Japan's history. It is believed to have originated from the region of Kyushu, specifically in the area around present-day Fukuoka Prefecture. The name is derived from the Japanese words "sue" meaning "end" and "naga" meaning "long", likely referring to a geographical feature or a person's physical characteristic.
One of the earliest recorded instances of the SUENAGA name can be found in the Azuma Kagami, a historical chronicle compiled in the late 13th century, which mentions a samurai warrior named SUENAGA Chikahiro who served under the Kamakura shogunate. Another notable figure from this period was SUENAGA Masatsune, a high-ranking court official and poet who lived during the late 13th and early 14th centuries.
During the Muromachi period (1336-1573 CE), the SUENAGA name was associated with the influential Suenaga clan, a family of daimyo (feudal lords) who ruled over parts of present-day Oita Prefecture in Kyushu. One prominent member of this clan was SUENAGA Nobunao, who fought alongside the famous warlord Oda Nobunaga in the late 16th century.
In the Edo period (1603-1868 CE), a SUENAGA family served as hatamoto (direct retainers of the Tokugawa shogunate) in Edo (present-day Tokyo). One notable figure from this time was SUENAGA Bunshō, a scholar and calligrapher who lived in the early 19th century.
Moving into the modern era, SUENAGA Taneomi (1835-1900) was a prominent samurai and politician who played a key role in the Meiji Restoration and the establishment of the modern Japanese state. Another notable figure was SUENAGA Kusuo (1900-1986), a celebrated novelist and essayist known for his works exploring Japanese culture and tradition.
While the SUENAGA name has its roots in Kyushu, over the centuries, it has become more widely dispersed across Japan, with families bearing this surname found in various regions of the country.
Demographics
Among Census respondents with the surname Suenaga, the largest self-reported group is Asian/Pacific Islander at 65.6%. The next largest groups are Hispanic (12.2%) and Two or More Races (11.1%).
The bar chart below shows how Suenaga 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 Suenaga surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Suenaga (2000, 2010, 2020).
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.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
