Origin
Meaning and origin of Tsuha
The surname TSUHA is of Japanese origin and dates back to the late 11th century. It is believed to have originated in the Kanto region of central Japan, particularly in the area around modern-day Tokyo. The name is derived from the Japanese word "tsuha," which means "twin leaves" or "twin blades," suggesting a connection to nature or perhaps a reference to a family crest or symbol.
One of the earliest recorded mentions of the TSUHA name can be found in the Azuma Kagami, a historical chronicle from the late 12th century. This ancient text documents the life and accomplishments of a samurai warrior named Tsuha Nobumitsu, who served under the Kamakura Shogunate during the Genpei War.
During the Muromachi period (1336-1573), the TSUHA family established themselves as prominent landowners and administrators in the Kanto region. Historical records from this era mention a TSUHA Masanori, who served as a local governor in the province of Musashi (present-day Tokyo and Saitama prefectures) in the late 15th century.
In the Edo period (1603-1868), the TSUHA name gained further prominence with the rise of Tsuha Takayoshi, a respected scholar and poet who served as a court advisor to the Tokugawa Shogunate. His literary works and contributions to the development of Japanese poetry are well-documented in various historical texts from the 17th century.
Another notable figure was Tsuha Masatomo (1790-1867), a skilled swordsmith who lived during the late Edo period. His katanas and other bladed weapons were highly sought after by samurai and nobility, and his techniques are still studied and revered by modern-day sword makers.
In the modern era, one of the most famous individuals with the TSUHA surname was Tsuha Kenichi (1917-2003), a renowned architect who played a significant role in the reconstruction efforts following World War II. His designs, which blended traditional Japanese elements with modern aesthetics, can be seen in several iconic buildings and structures throughout Japan.
While the TSUHA name has its roots in Japan, over the centuries, it has spread to other parts of the world through migration and cultural exchange. However, its rich history and deep connections to Japanese culture and traditions remain an integral part of its identity.
Demographics
Ancestry and ethnicity for Tsuha

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