Origin
The surname Hiratsuka is of Japanese origin, deriving from the geographic location of Hiratsuka, a city in the Kanagawa Prefecture of Japan. Its roots can be traced back to the late 16th century when surnames were first widely adopted in Japan.
The name Hiratsuka is believed to originate from the Japanese words "hira" meaning "flat" and "tsuka" meaning "mound" or "hill". This suggests that the name likely referred to a flat hilltop or plateau area where the earliest bearers of the name may have resided or held land.
One of the earliest recorded mentions of the Hiratsuka name can be found in the Shinpen Musashi Fudoki, a historical document detailing the geography and cultural traditions of the Musashi Province (present-day Tokyo and Saitama Prefectures) compiled in the early 8th century AD. This ancient text references a settlement called "Hiratsukamura" which translates to "Hiratsuka Village".
In the 17th century, a prominent figure named Hiratsuka Masayuki (1618-1680) rose to become a high-ranking samurai and served as a retainer to the powerful Tokugawa shogunate. His descendant, Hiratsuka Raicho (1886-1971), was a pioneering feminist and writer who founded the influential literary magazine "Seitō" and played a pivotal role in the early Japanese women's rights movement.
Other notable individuals carrying the Hiratsuka surname include Hiratsuka Katsunari (1927-2022), a respected archaeologist and scholar of ancient Japanese pottery, and Hiratsuka Yuji (born 1964), a contemporary manga artist and illustrator best known for his work on the "Great Teacher Onizuka" series.
The Hiratsuka name has also been associated with several place names within Japan, such as Hiratsukashi (Hiratsuka City) in Kanagawa Prefecture, and Hiratsuka Station, a major transportation hub serving the city. These place names serve as reminders of the geographic origins of the surname and its enduring connection to the region.
Demographics
Among Census respondents with the surname Hiratsuka, the largest self-reported group is Asian/Pacific Islander at 53.7%. The next largest groups are American Indian/Alaska Native (22.2%) and Two or More Races (14.8%).
The bar chart below shows how Hiratsuka 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 Hiratsuka 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 Hiratsuka (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.
