Self-introduction is a basic building block of Japanese conversation, and short clips like this one circulate on soundboards for quick reuse rather than as a line from a known show or film. The Japanese title simply means self-introduction, which explains why listeners search for it when they need a clean, standalone greeting for an edit. Creators keep using it because it is instantly recognisable as an introduction, even to audiences who do not speak Japanese, and because its short length makes it easy to drop into intros, memes and study content without extra editing.
