Aizen
A boys’ name with no widely documented etymology — two syllables, given to 105 babies a year in the US.
Aizen by the numbers
In 2025, 11 babies in England and Wales were named Aizen. In the US, 105 were, though that figure is from 2017, the most recent full year we hold.
For the size of the two countries, it is given noticeably more often in the US than in England and Wales.
Its best year in America so far is the most recent one on record, which means it was still climbing when the records end.
What we can tell you about Aizen
Not every name has a meaning to trace. Plenty are coined rather than inherited — invented outright, blended from two names, or respelled from an older one — and where we cannot find an etymology we can stand behind, we would rather say so than make one up. What follows comes from the birth records themselves.
