Jahkai is a modern American coinage that puts together Jah, the Rastafarian name for God that comes from the Hebrew Yahweh, and Kai, which means "sea" in Hawaiian, so it can be read as "God" and "sea" side by side. It belongs to a group of Jah- names such as Jahmir and Jahziel. Jahkai was rare in 2015 at number 4343 and has climbed to number 1215 in 2025, its highest rank so far.
