Origin
The surname Sakamoto originated in Japan and is believed to have been derived from the Japanese words "saka" meaning "slope" or "hill" and "moto" meaning "origin" or "source." This suggests that the name may have referred to people who lived near or originated from a hill or sloped area.
The earliest recorded instances of the Sakamoto surname can be traced back to the late 12th century during the Kamakura period in Japan. It is documented in historical records and family genealogies from that time, indicating its long-standing presence in Japanese society.
One of the earliest known individuals with the Sakamoto surname was Sakamoto Mochizane, a prominent courtier and scholar who lived during the late Heian period (794-1185). He served as a tutor to the imperial court and was renowned for his literary talents.
In the 16th century, during the Sengoku period, the Sakamoto clan emerged as a prominent samurai family in the Tosa Domain (present-day Kochi Prefecture). Sakamoto Nobumori, born in 1510, was a prominent daimyo (feudal lord) and military commander who played a significant role in the region's political affairs.
Another notable figure with the Sakamoto surname was Sakamoto Ryoma, a prominent samurai and influential figure in the Bakumatsu period (1853-1867). Born in 1836, he played a crucial role in the events leading to the Meiji Restoration, which marked the end of the Tokugawa shogunate and the transition to the modern era of Japan.
During the Edo period (1603-1868), the Sakamoto family had branches in various regions of Japan, including Echizen (present-day Fukui Prefecture) and Kozuke (present-day Gunma Prefecture). Sakamoto Kōkichi, born in 1755, was a prominent scholar and Confucian philosopher from the Echizen branch.
In more recent history, Sakamoto Ryuichi, born in 1952, is a renowned Japanese singer, songwriter, and record producer. He has had a successful music career spanning several decades and is widely recognized for his contributions to the Japanese music industry.
These are just a few examples of notable individuals with the Sakamoto surname throughout Japanese history, showcasing the name's long-standing presence and significance in various fields and time periods.
Demographics
Among Census respondents with the surname Sakamoto, the largest self-reported group is Asian/Pacific Islander at 76.9%. The next largest groups are Two or More Races (12.1%) and White (6.7%).
The bar chart below shows how Sakamoto 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 Sakamoto 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. 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.
