Origin
The surname HARAGUCHI is of Japanese origin and dates back several centuries. It is believed to have originated in the Kansai region of western Japan, particularly around the Osaka and Kyoto areas. The name is thought to be derived from the Japanese words "hara," meaning "field" or "plain," and "guchi," meaning "entrance" or "mouth." Thus, the name may have originally referred to someone who lived near the entrance to a field or plain.
One of the earliest recorded instances of the HARAGUCHI name appears in a document from the Muromachi period (1336-1573), which mentions a merchant family by that name residing in Osaka. During the Edo period (1603-1868), the HARAGUCHI surname was prominent among samurai families in the Kansai region, particularly in the service of the powerful Tokugawa shogunate.
In the late 16th century, a HARAGUCHI samurai named Hideaki (1554-1624) is mentioned in historical records as having fought alongside the renowned warlord Toyotomi Hideyoshi during the Korean campaigns of the 1590s. Another notable figure was HARAGUCHI Toshitsugu (1678-1746), a Confucian scholar and educator who served as a tutor to the sons of several daimyo (feudal lords).
During the Meiji period (1868-1912), the HARAGUCHI name gained prominence in the world of business and commerce. HARAGUCHI Shigeru (1828-1901) was a successful merchant and industrialist who established one of the first modern textile factories in Osaka. His son, HARAGUCHI Katsunori (1863-1935), followed in his footsteps and became a prominent figure in the Japanese silk trade.
In more recent history, HARAGUCHI Kazuhiko (1941-2022) was a renowned architect and urban planner who played a key role in the development of several major cities in Japan, including Tokyo and Osaka. HARAGUCHI Sachiko (1920-2010) was a respected author and literary critic who wrote extensively on Japanese literature and culture.
While the HARAGUCHI surname has its roots in the Kansai region, it has since spread throughout Japan and can be found in various prefectures and cities across the country. The name continues to be associated with a rich cultural heritage and a legacy of achievement in various fields.
Demographics
Among Census respondents with the surname Haraguchi, the largest self-reported group is Asian/Pacific Islander at 65.3%. The next largest groups are Two or More Races (15.4%) and Hispanic (9.5%).
The bar chart below shows how Haraguchi 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 Haraguchi 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.
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.
