Meaning
ocean flying, sea and soar
The story
Kaito is a modern Japanese boys' name usually built from a kanji for sea or ocean in its first element, with a second element that varies by family: characters meaning to soar or to fly give the popular reading of ocean flying, while another common choice uses the character for the Big Dipper. That is the honest shape of many Japanese names: the sound comes first, and the written characters chosen at naming fix the meaning. Kaito has ranked among Japan's popular boys' names through the twenty-first century, and it travels unusually well because English speakers can say it correctly on the first try. Kai works naturally as a short form and links it to a wider international family of sea names. The US curve first registers in the 2000s and rises into the 2010s and holds through the 2020s. For bilingual families it is a small masterpiece of compatibility, fully Japanese and effortlessly portable.

Not on the record in Puerto Rico, Ireland, New Zealand, Scotland and Poland: those registries withhold small counts, so rare uses may sit below their floors.
Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown. Not on the Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years. Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown. Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
