Meaning & origin

Iwao is a Japanese name with uncertain etymology, possibly meaning 'rock man' or 'first boy of peace'. It first appeared in U.S. records in 1914, and its peak popularity occurred in 1921. The name has since become extremely rare, with no recent rankings, and it has remained stable in its low usage. While it did not appear in any top states, Iwao carries a distinct cultural heritage from Japan.

Iwao is a Japanese masculine name. It may be composed of the elements iwa (岩, rock) and o (男, man), thus meaning 'rock man' or 'stone man'. Alternatively, it could derive from i (一, one/first) and wa (和, harmony/peace) with o (男, man), meaning 'first boy of peace'. The name has been in use since at least the early 20th century and was most popular in the 1920s in Japan.
