Origin
Meaning and origin of Komada
The surname KOMADA is believed to have originated in Japan. It is a Japanese surname that likely traces its roots back to the 8th or 9th century AD during the Heian period. The name KOMADA may derive from the Japanese words "koma" meaning a small horse or pony, and "da" meaning a rice field or paddy. This suggests the name may have initially referred to someone who owned or worked with small horses in rice paddies.
One of the earliest recorded instances of the KOMADA name appears in the Shinsen Shojiroku, a record of aristocratic families and clan lineages compiled in 1127 AD during the late Heian period. This text mentions the KOMADA clan as a lesser branch of the prominent Minamoto samurai clan from the Kanto region.
During the Kamakura period from 1185 to 1333 AD, the KOMADA name is found in various local records and manuscripts from areas around present-day Tokyo and Kanagawa prefectures. A notable early bearer was Komada Nobumitsu, a samurai warrior who fought for the Hojo clan in the 13th century.
In the 16th century Sengoku period, historical records mention Komada Nagamitsu, a daimyo feudal lord who controlled lands in what is now Chiba prefecture. His descendant Komada Nobunao was a cavalry commander under Tokugawa Ieyasu during the pivotal Battle of Sekigahara in 1600.
Moving into the Edo period from 1603 to 1868, the KOMADA surname proliferated among samurai families in service to the Tokugawa shogunate. Komada Kiyonobu, born in 1672, was an accomplished Edo period artist and painter from Kanagawa.
In more recent centuries, other notable bearers include Komada Hatsukuni (1874-1965), a Japanese educator and principal, and Komada Setsuko (1887-1963), an early 20th century feminist writer and activist for women's rights and suffrage in Japan.

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 Komada 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.

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