Census
Kazuto in the 2020 Census
The 2020 Census recorded 108 people with the first name Kazuto, which placed it at #52,273 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.

The next largest groups are Two or More Races (13.0%) and Hispanic (4.6%). 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 Kazuto 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 Kazuto at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Kazuto
The name Kazuto is of Japanese origin, derived from the combination of two separate words – "kazu," meaning "number" or "many," and "to," meaning "door" or "gateway." This name carries a symbolic meaning, suggesting "many gateways" or "numerous opportunities."
The earliest recorded instances of the name Kazuto can be traced back to the Heian period in Japan, spanning from 794 to 1185 CE. During this time, the name was primarily used by the aristocratic class and members of the imperial court. The popularity of the name likely stemmed from the cultural significance of numeric values and the concept of gateways, representing prosperity and potential.
In the ancient Japanese text "Kokin Wakashū," a renowned anthology of waka poetry from the early Heian period, there is a mention of a poet named Kazuto no Ason, who was renowned for his literary contributions. This reference suggests that the name was in use as early as the 10th century CE.
One of the earliest recorded figures bearing the name Kazuto was Kazuto Izumi, a prominent Buddhist monk and scholar who lived during the late 12th century. He was known for his philosophical teachings and his influence on the spread of Zen Buddhism in Japan.
In the 16th century, Kazuto Nakamura was a renowned samurai warrior who served under the powerful Tokugawa Shogunate. He played a significant role in the battles of the Sengoku period and was celebrated for his bravery and loyalty.
During the Edo period, which spanned from 1603 to 1868, the name Kazuto gained further popularity among the merchant class and artisans. Kazuto Matsumoto, a renowned woodblock artist from the 18th century, was celebrated for his intricate ukiyo-e prints depicting scenes from everyday life.
In the realm of literature, Kazuto Takeuchi was a prominent novelist and playwright of the late 19th century. His works explored themes of social commentary and cultural transition during the Meiji Restoration, leaving a lasting impact on Japanese literary tradition.

FAQ
Kazuto: questions and answers
How many people in the U.S. are named Kazuto?
Name Census puts the figure at roughly 23 living Americans. We arrive at this by taking every SSA birth registration for Kazuto 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 14,902,363 US residents.
Is Kazuto a common name?
We classify Kazuto as "Very Rare". It ranks above 42.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 78 babies have been registered with this name.
When was Kazuto most popular?
The single biggest year for Kazuto was 1919, when 7 babies received the name. The fact that the average living Kazuto is about 18 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Kazuto in the 2020 Census?
The published 2020 Census first-name tables recorded 108 people with the name Kazuto, or 0.04 per 100,000 residents. That placed it at #52,273 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 Kazuto 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 Kazuto?
In the 2020 Census sex table, Kazuto appears almost entirely male. Of the 110 people counted with this name, 100.0% 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 Kazuto?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Kazuto is Asian/Pacific Islander at 78.7%. The next largest groups are Two or More Races (13.0%) and Hispanic (4.6%). 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 Kazuto most often in the Census?
Asian/Pacific Islander is the largest reported group for people named Kazuto in the 2020 Census, accounting for 78.7% (85 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 Kazuto in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kazuto a male name?
Yes, 100.0% of people registered as Kazuto 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 Kazuto still being used today?
Yes. The SSA still recorded Kazuto 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 Kazuto 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.
