Haga is a surname of Japanese origin, derived from the word “haga” (羽賀), which means “feather” and “congratulate” or “celebrate.” As a family name, it’s relatively uncommon in Japan and even rarer outside of the country. The name Haga doesn’t typically appear in popular baby name lists, indicating its low popularity as a given name.

The inspiration behind the name Haga likely comes from its connection to nature (feathers) and positive sentiments (celebration). In Japanese culture, names often carry deep meanings and are chosen with care to reflect desired qualities or aspirations for the child.
