Origin
The surname ITAGAKI has its origins in Japan, with the earliest recorded examples dating back to the 16th century. The name is derived from the Japanese words "ita," meaning "board," and "gaki," meaning "gaki tree" or "persimmon tree." This suggests that the name may have been originally associated with occupations related to woodworking or the cultivation of persimmon trees.
One of the earliest known references to the ITAGAKI surname can be found in the records of the Tokugawa shogunate, which ruled Japan from the 17th to the 19th century. During this period, the ITAGAKI family was prominent in the domain of Tosa, located on the island of Shikoku.
In the late 19th century, a notable figure bearing the ITAGAKI surname was Taisuke ITAGAKI (1837-1919), a prominent politician and leader of the Freedom and People's Rights Movement, which advocated for democratic reforms in Japan. He played a significant role in the establishment of the modern Japanese political system.
Another historical figure with this surname was Seishiro ITAGAKI (1837-1919), a samurai and military leader who fought in the Boshin War, a civil war that marked the end of the Tokugawa shogunate and the beginning of the Meiji Restoration.
In the realm of literature, Naohiko ITAGAKI (1875-1950) was a renowned Japanese novelist and playwright who wrote works exploring social issues and the lives of ordinary people in the early 20th century.
During World War II, Hiroshi ITAGAKI (1901-1948) was a general in the Imperial Japanese Army and served as the Chief of Staff of the Southern Expeditionary Army Group, which oversaw operations in the Pacific theater.
More recently, Keisuke ITAGAKI (born in 1971) is a Japanese video game designer and programmer, best known for his work on the popular fighting game series "Tekken" and "Dead or Alive."
While the ITAGAKI surname can be found in various regions of Japan, it is particularly prevalent in the prefectures of Kochi, Ehime, and Tokushima, which are located on the island of Shikoku, where the name has a long historical presence.
Demographics
Among Census respondents with the surname Itagaki, the largest self-reported group is Asian/Pacific Islander at 82.7%. The next largest groups are Two or More Races (13.5%) and White (3.0%).
The bar chart below shows how Itagaki 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 Itagaki 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.
