Origin
Meaning and origin of Tabuchi
The surname Tabuchi is of Japanese origin, with the earliest records dating back to the 8th century AD. It is believed to have originated from the region of Kyushu, one of the main islands of Japan. The name is derived from the Japanese words "ta" meaning "rice paddy" and "buchi" meaning "town" or "village".
During the Heian period (794-1185 AD), the name Tabuchi appeared in several historical documents and records, indicating that families with this surname were prominent landowners or agricultural workers in rural areas. One of the earliest recorded individuals with the name Tabuchi was a samurai warrior named Tabuchi Masahiro, who served under the renowned shogun Minamoto no Yoritomo in the late 12th century.
In the 16th century, a notable figure named Tabuchi Yoshitsugu was a skilled swordsmith who crafted exceptional blades for the samurai class. His works were highly prized and are still celebrated in Japan today.
The Tabuchi surname can also be traced back to the village of Tabuchi-mura in the Gifu Prefecture, which was established during the Edo period (1603-1868). This village was known for its skilled artisans and woodworkers, many of whom carried the Tabuchi name.
In the late 19th century, a prominent philosopher and educator named Tabuchi Yukichi (1833-1901) made significant contributions to the modernization of Japan's education system. He was a proponent of Western-style education and played a crucial role in shaping the country's educational reforms.
Another notable individual with the Tabuchi surname was Tabuchi Masataka (1888-1973), a respected painter and printmaker who was part of the Nihonga (Japanese-style painting) movement. His works were heavily influenced by traditional Japanese art and often depicted scenes from nature and daily life.
Throughout its history, the Tabuchi surname has been associated with various professions, including agriculture, artisanry, philosophy, and the arts. It has a rich cultural heritage rooted in the rural regions of Japan, particularly in the areas around Kyushu and Gifu Prefecture.

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 Tabuchi 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.
