Origin
The surname Kadowaki is of Japanese origin, derived from the Japanese words "kado" meaning "gateway" or "angle," and "waki" meaning "side" or "vicinity." It is believed to have originated in the 9th or 10th century during the Heian period, when surnames were first adopted in Japan.
Kadowaki was initially associated with families who lived near gateways or corners of towns or villages. It is likely that the name was first used to identify individuals based on their place of residence or occupation related to guarding gateways or residing in the vicinity of such structures.
One of the earliest recorded mentions of the Kadowaki surname can be found in the Shōyūki, a historical text from the late Kamakura period (1185-1333). This text references a prominent samurai named Kadowaki Nobuyori, who served under the Hojo clan during the 13th century.
In the 15th century, during the Muromachi period, a Zen Buddhist monk named Kadowaki Zenkō (1398-1473) gained recognition for his teachings and contributions to the development of the Rinzai school of Zen Buddhism.
Another notable figure with the Kadowaki surname was Kadowaki Munetoshi (1564-1645), a daimyo (feudal lord) who ruled over the Tosa Domain (present-day Kochi Prefecture) during the Edo period.
During the Meiji era (1868-1912), Kadowaki Mokurai (1835-1917) was a respected Buddhist scholar and calligrapher who played a significant role in revitalizing traditional Japanese culture and arts after the country's rapid modernization.
In more recent history, Kadowaki Tatsuhiko (1908-2000) was a renowned Japanese architect known for his innovative designs, including the Tokyo Dome and the Japan National Stadium.
While the Kadowaki surname has its roots in Japan, it has also been adopted by individuals in other parts of the world, particularly in areas with significant Japanese immigrant communities, such as Hawaii and California.
Demographics
Among Census respondents with the surname Kadowaki, the largest self-reported group is Asian/Pacific Islander at 69.3%. The next largest groups are Two or More Races (17.1%) and White (8.6%).
The bar chart below shows how Kadowaki 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 Kadowaki 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.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
