OSHIKATSU— ORIGIN, MEANING & USAGE

Oshikatsu The active, ongoing practice of supporting one's favorite idol, VTuber, or character (one's oshi) — buying merchandise, attending events, streaming content, voting — treated as a dedicated hobby/lifestyle in its own right rather than passive fandom.

Origin:Compound of oshi (推し, one's favorite/most-supported member) and katsu (活, short for katsudou, "activity"), following the same -katsu naming pattern as other Japanese lifestyle-activity terms (e.g. konkatsu, "marriage hunting"), formalizing active idol/VTuber support into a named category of dedicated fan behavior.
