Origin
Meaning and origin of Mizuki
The surname MIZUKI is of Japanese origin, tracing its roots back to the early centuries of the feudal era in Japan. The name is derived from the Japanese words "mi," meaning "beautiful," and "zuki," meaning "moon." It is believed that the surname originally referred to either a person born during a full moon or someone who was particularly fond of the moon's beauty.
One of the earliest recorded instances of the MIZUKI name appears in the Azuma Kagami, a historical text from the 14th century that chronicled the lives of prominent samurai families. The text mentions a samurai named Mizuki Nobuyuki, who fought valiantly in the battles of the Nanboku-cho period (1336-1392).
In the 16th century, during the Sengoku period of constant warfare, a renowned swordsman named Mizuki Masahiro (1521-1589) gained fame for his skills on the battlefield. He served under the powerful daimyo (feudal lord) Oda Nobunaga and was known for his unwavering loyalty and bravery.
The MIZUKI name also appears in several historical records from the Edo period (1603-1868), when Japan was under the rule of the Tokugawa shogunate. One notable figure was Mizuki Shigenobu (1745-1818), a respected scholar and poet who contributed significantly to the development of traditional Japanese literature.
In the 19th century, a prominent politician and diplomat named Mizuki Munemitsu (1843-1901) played a crucial role in establishing Japan's diplomatic relations with Western nations during the Meiji Restoration.
Another notable figure was Mizuki Shigeru (1922-2015), a celebrated author, and illustrator renowned for his supernatural manga series "GeGeGe no Kitaro." His works, deeply rooted in Japanese folklore and mythology, have been widely acclaimed both in Japan and internationally.
While the MIZUKI surname has its origins in Japan, it has since spread to other parts of the world through immigration and cultural exchange. However, the rich history and cultural significance of this name remain firmly rooted in its Japanese heritage.

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 Mizuki surname at the time of the 2010 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
Not necessarily. Mizuki appears here with 2010 Census data, while the latest surname file loaded on Name Census is 2020. When a surname drops below the Census publication threshold, older rows can still be kept for historical reference even if the name no longer appears in the newest file.
Does the Census include every surname?

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. 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.
