Jazai is a modern American coinage with no traditional meaning, formed from the fashionable Jaz- sound of names like Jazz and Jaziel together with the -ai ending heard in Kai and Nasai. It is one of the newest names in the US statistics and has risen quickly from a handful of births a few years ago. Jazai jumped from number 13185 among US boys in 2022 to number 2817 in 2025, its best rank by far.
