noun
staged event; faked situation; prearranged performance
Refers to an event or situation that is deliberately set up to appear genuine, often in media, entertainment, or social contexts. Can imply deception or manipulation.
あの感動的な再会シーンは、実はやらせだったらしい。
That touching reunion scene was apparently staged.
テレビ番組でやらせが発覚し、大きな問題になった。
The TV program was found to have faked situations, causing a major scandal.
仕込み refers to something prepared or arranged in advance, often in a neutral or positive sense (e.g., training, setup), while やらせ specifically implies a deceptive or manipulative staging.
演出 is a general term for direction or production in theater, film, etc., without the negative connotation of fakery that やらせ carries.
Derived from the verb やる (to do) in its causative form やらせる (to make someone do), nominalized to やらせ. The term likely emerged in media and entertainment contexts to describe staged or forced scenarios.
