Origin
Meaning and history of Jukai
The name Jukai has its origins in Japanese culture, specifically in the language and tradition of Buddhism. The name is derived from the Japanese words "ju" meaning "abiding" or "dwelling," and "kai" meaning "ocean" or "sea." Together, the name Jukai can be interpreted to mean "abiding in the ocean" or "dwelling in the vast expanse."
In Japanese Buddhism, the term "Jukai" refers to the ritual of taking the Precepts, which is a formal ceremony where individuals commit to following the Buddhist teachings and way of life. This ceremony holds great significance as it marks the transition from being a lay practitioner to becoming a Buddhist disciple.
The earliest recorded use of the name Jukai can be traced back to the 8th century CE, during the Nara period in Japan. At that time, Buddhist monks and scholars were known to adopt dharma names, or Buddhist names, upon taking the Precepts. Jukai was likely one of the names chosen to reflect the individual's spiritual journey and commitment to the Buddhist path.
Throughout history, there have been several notable figures who bore the name Jukai. One of the earliest recorded individuals was Jukai Shonin, a Japanese Buddhist monk who lived in the 8th century CE. He is renowned for his contributions to the spread of Buddhism in Japan and for establishing several important temples, including the Tōdai-ji in Nara.
Another prominent figure was Jukai Ittō, a Japanese Zen Buddhist monk who lived during the 16th century. He is credited with reviving and restructuring the Rinzai Zen tradition in Japan, which had declined during the Sengoku period. Jukai Ittō's teachings and reforms had a lasting impact on the development of Zen Buddhism in Japan.
In the 19th century, Jukai Gensho, a Japanese Buddhist scholar and calligrapher, gained recognition for his contributions to the study and preservation of Buddhist texts and calligraphic works. He played a significant role in the restoration of Buddhism in Japan during the Meiji period.
Jukai Fujii, a Japanese Zen Buddhist monk and scholar, lived from 1888 to 1976. He was instrumental in introducing and popularizing Zen Buddhism in the West, particularly in the United States. Jukai Fujii's teachings and writings helped bridge the gap between Eastern and Western perspectives on Buddhism.
Lastly, Jukai Nakamura, a contemporary Japanese Zen Buddhist monk and teacher, has been influential in sharing the teachings of Zen Buddhism across the globe. Born in 1947, he has authored numerous books and established several Zen centers, making Zen practices accessible to a wider audience.

FAQ
Jukai: questions and answers
How many people in the U.S. are named Jukai?
Name Census puts the figure at roughly 10 living Americans. We arrive at this by taking every SSA birth registration for Jukai 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 34,275,434 US residents.
Is Jukai a common name?
We classify Jukai as "Very Rare". It ranks above 28.5% of all first names in the SSA dataset by living bearers. Across the full history of the data, 10 babies have been registered with this name.
When was Jukai most popular?
The single biggest year for Jukai was 2023, when 5 babies received the name. The fact that the average living Jukai 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 Jukai in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Jukai a male name?
Yes, 100.0% of people registered as Jukai 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 Jukai still being used today?
Yes. The SSA still recorded Jukai 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 Jukai 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.
