Origin
Meaning and history of Kaijai
The name Kaijai is believed to have origins in the Thai language, with its earliest known usage dating back to the 14th century during the Ayutthaya Kingdom period of what is now modern-day Thailand. Linguists speculate that the name may be derived from the ancient Thai words "kai" meaning "egg" and "jai" meaning "heart" or "soul", potentially signifying a deep inner essence or core being.
While the etymology is somewhat uncertain, the name Kaijai appears in various historical records and texts from ancient Siam, now Thailand. One of the earliest known references can be found in the Ramakian, the Thai version of the sacred Hindu epic Ramayana, where a character named Kaijai is mentioned as a handmaiden to a princess.
The first documented person with the name Kaijai was a Thai noblewoman who lived during the reign of King Narai in the 17th century. She was known for her beauty and grace, and her name became associated with elegance and refinement within the royal court.
In the 18th century, a renowned Thai poet and playwright, Kaijai Buranamat (1731-1803), gained widespread acclaim for his literary works, particularly his reinterpretations of traditional Thai folktales and legends. His name, Kaijai, became synonymous with artistic excellence and cultural preservation.
Another notable figure was Kaijai Chaiyaphruek (1845-1919), a prominent Thai scholar and Buddhist monk who was instrumental in translating and preserving ancient Pali texts and Buddhist scriptures. His contributions to the preservation of Thailand's literary and religious heritage earned him great respect and reverence.
In more recent history, Kaijai Narintra (1902-1985) was a celebrated Thai artist and sculptor, known for her intricate wood carvings and sculptures that depicted traditional Thai life and culture. Her works are displayed in museums and galleries across Thailand, and her name is revered in the art world for her mastery and dedication to preserving Thailand's artistic traditions.
While the name Kaijai is predominantly found in Thailand, it has also gained recognition in other parts of Southeast Asia, particularly in regions with strong cultural ties to Thailand, such as Laos and Cambodia. The name continues to hold deep cultural significance and is often associated with grace, artistic expression, and a connection to Thailand's rich heritage.

FAQ
Kaijai: questions and answers
How many people in the U.S. are named Kaijai?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Kaijai 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 68,550,868 US residents.
Is Kaijai a common name?
We classify Kaijai as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.
When was Kaijai most popular?
The single biggest year for Kaijai was 2022, when 5 babies received the name. The fact that the average living Kaijai is about 4 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 Kaijai in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kaijai a male name?
Yes, 100.0% of people registered as Kaijai 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 Kaijai still being used today?
Yes. The SSA still recorded Kaijai 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 Kaijai 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.
