Origin
Meaning and origin of Ikari
The surname "IKARI" is believed to have originated in Japan during the 14th century. The name is derived from the Japanese word "ikari," which means "anger" or "wrath." This suggests that the name may have been given to someone who was known for their fierce or intense demeanor.
During the Muromachi period (1336-1573), the name IKARI appeared in several historical records, including the "Taiheiki," a chronicle of the wars between the Northern and Southern courts. One notable figure from this time was Ikari Masanori, a samurai who fought for the Southern Court during the Nanboku-cho Wars (1336-1392).
In the 16th century, the name IKARI was also found in the records of the Sengoku period (1467-1615), a time of great social upheaval and constant warfare between rival daimyo (feudal lords). One famous figure from this era was Ikari Nobumasa, a skilled archer and retainer of the powerful Takeda clan.
As the Tokugawa shogunate gained power in the 17th century, the IKARI name continued to be associated with military service. The "Ikari Gunki," a historical account of the Ikari family's military exploits, mentions several members who served as samurai during this time.
During the Edo period (1603-1868), the IKARI name was also found in various regions of Japan, including the Kanto and Tohoku areas. One notable figure was Ikari Tsunetomo, a samurai and philosopher who wrote the famous "Hagakure," a treatise on the way of the samurai.
In the 19th century, as Japan entered the Meiji era (1868-1912), the IKARI name continued to be associated with military service and local governance. One prominent figure was Ikari Mitsumasa, a samurai-turned-bureaucrat who played a key role in the modernization of Japan's government and military.
While the IKARI surname is not as common as some other Japanese family names, it has a rich history and has been associated with courage, loyalty, and a strong sense of duty throughout the centuries.

The bar chart below shows how Ikari 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 Ikari surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
