Origin
Meaning and origin of Aragaki
The surname Aragaki is believed to have originated in Japan, likely during the Heian period (794-1185 AD). It is thought to be derived from the Japanese words "ara", meaning "rough" or "wild", and "gaki", which can refer to a small child or a type of supernatural creature in Japanese folklore.
One of the earliest recorded instances of the name Aragaki can be found in the Azuma Kagami, a historical chronicle from the late Kamakura period (1185-1333 AD). This text mentions an individual named Aragaki Munetada, who served as a samurai under the Hojo clan during the late 13th century.
In the 16th century, the Aragaki family gained prominence as retainers to the powerful Mori clan, who ruled over parts of present-day Hiroshima and Yamaguchi prefectures. One notable figure from this era was Aragaki Katsutada (1537-1596), a skilled archer and military strategist who played a key role in several battles during the Sengoku period.
During the Edo period (1603-1868), the Aragaki surname appeared in various records and documents from different regions of Japan. For example, there are records of an Aragaki family residing in the Satsuma Domain (present-day Kagoshima Prefecture) in the late 17th century.
In more recent history, several individuals with the Aragaki surname have achieved recognition in various fields. These include Aragaki Yui (1992-), a Japanese actress and model, and Aragaki Tsuyoshi (1961-), a renowned photographer known for his landscape and nature photography.
Other notable individuals with the Aragaki surname include Aragaki Masato (1935-2018), a Japanese novelist and poet, Aragaki Hideo (1939-2006), a prominent architect and urban planner, and Aragaki Kiyoko (1924-2019), a celebrated ceramist and artist known for her innovative pottery 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 Aragaki surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
