Census
Kazuma in the 2020 Census
The 2020 Census recorded 235 people with the first name Kazuma, which placed it at #34,648 in the published first-name tables. This is a snapshot of people who already had the name at the time of the Census.
The SSA sections elsewhere on this page answer a different question: how often parents gave the name to babies over time. The "people living today" figure on this page is different again: it is a current estimate built from SSA birth records and age-based survival rates, so the two numbers are not expected to match exactly.

In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kazuma is Asian/Pacific Islander at 69.8%. The next largest groups are Two or More Races (18.7%) and Hispanic (6.0%). These figures describe the people who had the name in 2020, not any inherent property of the name itself.
The bar chart below shows how people with the first name Kazuma 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 name, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown so the breakdown is easy to read across every published category. Because the 2020 Census first-name file also includes raw headcounts for each group, Name Census can show those alongside the percentages in the legend and hover tooltip.
Keep in mind that these are self-reported numbers. A first name does not determine a person's race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the name Kazuma at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Kazuma
The given name Kazuma is a masculine Japanese name. It is a compound word formed by combining the elements "kazu" meaning "number" or "many", and "ma" meaning "truth" or "spiritual". Together, the name conveys a meaning along the lines of "many truths" or "abundant spiritual virtues".
The name Kazuma has been in use in Japan for centuries, with records indicating its presence as early as the 8th century AD during the Nara period. It was initially favored by aristocratic families and members of the samurai warrior class, who valued the spiritual connotations associated with the name.
In ancient Japanese literature, the name Kazuma can be found in various historical texts and chronicles, including the Kojiki and Nihon Shoki, two of the oldest books detailing the mythology and early history of Japan. These works mention individuals bearing the name, although it is difficult to determine if they refer to actual historical figures or mythical characters.
One of the earliest recorded individuals with the name Kazuma was a renowned Buddhist monk who lived during the late Heian period (794-1185 AD). Known as Kazuma Taishi, he was a influential figure in the spread of Buddhism throughout Japan and is credited with founding several temples and monasteries.
Another notable figure in Japanese history was Kazuma Akechi, a samurai warrior and general who lived during the late 16th century. He played a significant role in the military campaigns of Oda Nobunaga and Toyotomi Hideyoshi, two of the most powerful daimyo (feudal lords) of the Sengoku period.
In the realm of literature, the name Kazuma is associated with Kazuma Kodama, a prominent Japanese poet and scholar who lived during the Edo period (1603-1868). His works, which explored themes of nature and spirituality, were highly influential in the haiku and waka poetry traditions of the time.
Another notable figure was Kazuma Inoue, a Japanese philosopher and educator who lived in the late 19th and early 20th centuries. He played a significant role in modernizing Japan's education system and introducing Western philosophical ideas to Japanese academics.
In more recent times, the name Kazuma has been carried by individuals such as Kazuma Kōdaka, a Japanese judoka who won a gold medal at the 1984 Summer Olympics in Los Angeles, and Kazuma Tomoto, a professional baseball player who played for the Yomiuri Giants in the Nippon Professional Baseball league.
While the name Kazuma has its roots in ancient Japan, it continues to be a popular choice for parents in modern times, reflecting the enduring appeal of its spiritual and literary associations.

FAQ
Kazuma: questions and answers
How many people in the U.S. are named Kazuma?
Name Census puts the figure at roughly 200 living Americans. We arrive at this by taking every SSA birth registration for Kazuma going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 1,713,772 US residents.
Is Kazuma a common name?
We classify Kazuma as "Very Rare". It ranks above 74.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 208 babies have been registered with this name.
When was Kazuma most popular?
The single biggest year for Kazuma was 2010, when 17 babies received the name. The fact that the average living Kazuma is about 19 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Kazuma in the 2020 Census?
The published 2020 Census first-name tables recorded 235 people with the name Kazuma, or 0.08 per 100,000 residents. That placed it at #34,648 in the national Census ranking for first names.
Why is the Census count different from the living estimate?
Because they measure different things. The Census figure is a count of people who had the name Kazuma in 2020. The living estimate aims to answer a current question instead: how many people with the name are alive today, based on SSA birth records and age-based survival rates. Since one number is a 2020 snapshot and the other is a present-day estimate, they are not expected to be identical.
What does the Census say about the gender split for Kazuma?
In the 2020 Census sex table, Kazuma appears almost entirely male. Of the 229 people counted with this name, 99.1% were male and only a very small share were female. The Census view is a snapshot of people living with the name in 2020, while the SSA section above tracks births across time.
What does the Census say about the background of people named Kazuma?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kazuma is Asian/Pacific Islander at 69.8%. The next largest groups are Two or More Races (18.7%) and Hispanic (6.0%). These figures describe the people who had the name in 2020, not any inherent property of the name itself. The percentages in the chart above come from self-reported race and Hispanic-origin responses in the 2020 Census.
Which group reports the name Kazuma most often in the Census?
Asian/Pacific Islander is the largest reported group for people named Kazuma in the 2020 Census, accounting for 69.8% (164 people in the published table).
Why can the Census sex total and race total differ slightly?
The Census Bureau published separate 2020 tables for sex and for race/Hispanic origin, and the released figures can differ slightly because of privacy protection in the public files. That is why this page treats the gender section and the race/origin section as two related snapshots instead of forcing them into one identical total.
Does every first name have Census demographic data?
No. The public Census first-name release only includes names that met the Bureau's publication rules, so many rarer names in the SSA files have no Census demographic snapshot. When that happens, the SSA trend, gender history, and state sections still appear, but the 2020 Census demographic sections are omitted.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Kazuma in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kazuma a male name?
Yes, 100.0% of people registered as Kazuma in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Kazuma still being used today?
Yes. The SSA still recorded Kazuma in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Kazuma can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.
