Census
Nanako in the 2020 Census
The 2020 Census recorded 239 people with the first name Nanako, which placed it at #34,236 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 Nanako is Asian/Pacific Islander at 85.8%. The next largest groups are Two or More Races (6.7%) and White (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 Nanako 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 Nanako at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Nanako
The name Nanako is a feminine Japanese name with its origins dating back to the 8th century. It is derived from the Japanese words "nana" meaning "seven" and "ko" meaning "child," suggesting it was initially used to refer to the seventh child in a family.
During the Nara period (710-794 CE), the name Nanako began appearing in Japanese historical records and texts, though it was relatively uncommon at the time. The name gained more popularity during the subsequent Heian period (794-1185 CE), particularly among the nobility and samurai classes.
One of the earliest recorded mentions of the name Nanako can be found in the Tsurezuregusa, a collection of essays written by the renowned Japanese Buddhist monk Yoshida Kenko in the 14th century. In this work, Kenko makes a passing reference to a woman named Nanako, suggesting the name was in use during that era.
Throughout Japanese history, several notable figures have borne the name Nanako. Lady Nanako (1141-1201), a member of the Imperial Court during the late Heian period, was renowned for her poetry and literary talents. Her works were included in several imperial anthologies of the time.
During the Edo period (1603-1868), Nanako Okumura (1687-1766) was a celebrated courtesan and geisha in Kyoto. She was known for her exceptional beauty, elegance, and skill in traditional Japanese arts.
In more recent times, Nanako Matsushima (born 1973) is a well-known Japanese actress and singer who has appeared in numerous films, television dramas, and stage productions. She is particularly recognized for her role in the popular film "Ringu" (1998).
Another notable figure is Nanako Suzuki (1935-2008), a Japanese author and children's book writer. Her works, which often explored themes of family, friendship, and self-discovery, have been widely praised and translated into multiple languages.
Lastly, Nanako Kawamura (born 1982) is a Japanese professional golfer who has won several tournaments on the LPGA of Japan Tour and has represented Japan in international competitions such as the Solheim Cup.

FAQ
Nanako: questions and answers
How many people in the U.S. are named Nanako?
Name Census puts the figure at roughly 72 living Americans. We arrive at this by taking every SSA birth registration for Nanako 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 4,760,477 US residents.
Is Nanako a common name?
We classify Nanako as "Very Rare". It ranks above 59.7% of all first names in the SSA dataset by living bearers. Across the full history of the data, 73 babies have been registered with this name.
When was Nanako most popular?
The single biggest year for Nanako was 2002, when 8 babies received the name. The fact that the average living Nanako is about 20 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Nanako in the 2020 Census?
The published 2020 Census first-name tables recorded 239 people with the name Nanako, or 0.08 per 100,000 residents. That placed it at #34,236 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 Nanako 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 Nanako?
In the 2020 Census sex table, Nanako appears almost entirely female. Of the 241 people counted with this name, 99.6% were female and only a very small share were male. 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 Nanako?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Nanako is Asian/Pacific Islander at 85.8%. The next largest groups are Two or More Races (6.7%) and White (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 Nanako most often in the Census?
Asian/Pacific Islander is the largest reported group for people named Nanako in the 2020 Census, accounting for 85.8% (205 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 Nanako in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Nanako a female name?
Yes, 100.0% of people registered as Nanako in the SSA data are female. 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 Nanako still being used today?
Yes. The SSA still recorded Nanako 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 Nanako 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.
