Meaning

Foreshadowing — a narrative hint or setup planted early in a story that becomes significant later.

伏線 is a literary term that has become central to anime and manga fan discourse. Fans actively hunt for and discuss foreshadowing elements, debating whether small details are intentional 伏線 or just coincidence. The term is used both to praise clever writing ('すごい伏線!') and to speculate about future plot developments.

Examples

1. あのシーン、伏線だったんだ！全然気づかなかった。 That scene was foreshadowing?! I totally didn't notice.
2. 1話から伏線張ってたとか作者天才すぎる。 They've been laying foreshadowing since episode one — the author is a genius.
3. これ絶対伏線だよね？回収されるの楽しみ。 This is definitely foreshadowing, right? I can't wait for the payoff.
