Origin
Meaning and history of Mirio
The name Mirio has its origins in the Japanese language and culture, with roots dating back to the 8th century AD. It is believed to be derived from the Japanese words "mi," meaning "beautiful," and "rio," meaning "village" or "settlement." The name therefore carries the connotation of a beautiful or pleasant village or place.
One of the earliest recorded instances of the name Mirio can be found in ancient Japanese texts from the Nara period (710-794 AD), where it was used to refer to scenic locations or settlements renowned for their natural beauty. During this time, the name was often associated with poetic descriptions of picturesque landscapes and tranquil settings.
Throughout the centuries, the name Mirio has been borne by several notable figures in Japanese history. One such individual was Mirio Fujiwara (1098-1176), a celebrated poet and scholar of the late Heian period. His works, which captured the essence of traditional Japanese aesthetics, were widely influential and contributed to the development of Japanese literature.
Another prominent figure was Mirio Tokugawa (1625-1693), a prominent daimyo (feudal lord) and member of the influential Tokugawa clan during the Edo period. He played a pivotal role in strengthening the Tokugawa shogunate's control over the region of Kyushu and was known for his administrative and military prowess.
In the realm of Japanese art, Mirio Kano (1828-1895) was a renowned painter and founder of the Kano school of Japanese painting. His works, which often depicted traditional Japanese subjects and landscapes, were highly regarded for their technical mastery and adherence to traditional techniques.
Mirio Miyagi (1894-1975) was a pioneering Okinawan karate master who played a crucial role in spreading the practice of karate beyond the confines of Okinawa. He is widely regarded as one of the most influential figures in the history of modern karate and contributed significantly to its global dissemination.
The name Mirio has also been associated with various literary and artistic works throughout Japanese history, further solidifying its cultural significance and enduring legacy within the Japanese tradition.

FAQ
Mirio: questions and answers
How many people in the U.S. are named Mirio?
Name Census puts the figure at roughly 12 living Americans. We arrive at this by taking every SSA birth registration for Mirio 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 28,562,862 US residents.
Is Mirio a common name?
We classify Mirio as "Very Rare". It ranks above 32.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 12 babies have been registered with this name.
When was Mirio most popular?
The single biggest year for Mirio was 2022, when 7 babies received the name. The fact that the average living Mirio is about 3 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
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 Mirio in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Mirio a male name?
Yes, 100.0% of people registered as Mirio 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 Mirio still being used today?
Yes. The SSA still recorded Mirio 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 Mirio 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.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
