Kenzai is a modern American coinage that joins the Ken- opening of Kenzo and Kenji with the "-ai" ending of Kai; it has no established meaning, though Kenzo, its closest model, is a Japanese name often read as "healthy and strong". The name is brand new in the statistics: it first appeared in 2024 at number 3247 and reached number 2960 in 2025 with 42 boys.
