Origin
Meaning and history of Kaize
The name Kaize is believed to have originated from the Japanese language, with its roots likely dating back to the Heian period (794-1185 CE). It is thought to be derived from the Japanese word "kaizoku," which means "pirate" or "sea robber." In ancient Japan, pirates and seafarers were often referred to by this term.
One of the earliest recorded uses of the name Kaize can be found in the ancient Japanese epic "The Tale of the Heike," which chronicles the struggle between the Taira and Minamoto clans during the late 12th century. In this literary work, there is a character named Kaize no Sukemori, who was a samurai warrior and member of the Taira clan.
During the Kamakura period (1185-1333 CE), the name Kaize gained popularity among Japanese nobility and warrior classes. It was often given to sons who were expected to grow up and become brave and skilled warriors, embodying the fearless spirit of the pirates and seafarers from which the name originated.
One notable historical figure with the name Kaize was Kaize Naganori, a Japanese samurai and daimyo (feudal lord) who lived during the Sengoku period (1467-1615 CE). He was known for his military prowess and leadership in various battles against rival clans.
Another prominent individual with the name Kaize was Kaize Masashige, a Japanese daimyo who lived during the late 16th century. He was a skilled strategist and played a crucial role in the unification of Japan under the leadership of Toyotomi Hideyoshi.
In the early Edo period (1603-1868 CE), the name Kaize was also used by some members of the samurai class and the ruling shogunate. One such individual was Kaize Tsunanori, a samurai and retainer of the Tokugawa shogunate, who was highly respected for his loyalty and bravery.
Throughout the centuries, the name Kaize has remained a part of Japanese culture and has been associated with strength, courage, and a connection to the sea and maritime traditions of ancient Japan.

FAQ
Kaize: questions and answers
How many people in the U.S. are named Kaize?
Name Census puts the figure at roughly 10 living Americans. We arrive at this by taking every SSA birth registration for Kaize 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 Kaize a common name?
We classify Kaize 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 Kaize most popular?
The single biggest year for Kaize was 2019, when 5 babies received the name. The fact that the average living Kaize is about 5 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 Kaize in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kaize a male name?
Yes, 100.0% of people registered as Kaize 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 Kaize still being used today?
Yes. The SSA still recorded Kaize 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 Kaize 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.
