A boy's name of Japanese origin with 1,734 recorded U.S. births.
Meaning & Origin
Aizen has 1,734 recorded U.S. births across 17+ years, peaking at 223 in 2024. It occupies the space between “never heard of it” and “everyone has one in their class” — a name that feels personal without being obscure.
In the most recent SSA release, Aizen ranks #1003 among U.S. boy names — distinctive enough to stand out.
Aizen is a boy's baby name of Japanese origin, from the Japanese Buddhist deity Aizen Myo-o (Ragaraja), the god of love and lust who transforms earthly desires into enlightenment. The name carries themes of transformation and spiritual passion.
Aizen gained significant international recognition as a major character in the anime series Bleach — Sosuke Aizen, the main antagonist whose intelligence and power captivated audiences worldwide. That association with brilliant, complex characterization has driven the name's growth among anime fans in the United States.
EtymologyShow more
Aizen first shows up in U.S. Social Security records in 2007. A twenty-first-century entry, Aizen belongs to the newest generation of American names — often coined, blended, or borrowed from international sources.
Its Japanese classification suggests a path from japanese linguistic traditions into American usage, though the specific route — whether through immigration, literature, or cultural exchange — would require deeper historical research.
