原作

• Reading: げんさく
• Romaji: gensaku
• Kanji breakdown: 原 (original/source) + 作 (work/creation) → original work/source material
• Pronunciation: /ɡeɴ.sa.kɯ/

Meaning

The original source material — the manga, light novel, game, or other work that an anime or adaptation is based on.

原作 is essential vocabulary for discussing adaptations. Fans frequently compare anime to their 原作, debating whether the adaptation did the source material justice. '原作勢' (gensaku-zei) refers to fans who read the original before the adaptation. The term is central to discussions about pacing, cut content, and faithfulness.

Examples

1. 原作読んでからアニメ見るとカットされたシーン多くて悲しい。 When you read the source material first and then watch the anime, it's sad how many scenes got cut.
2. 原作の方が面白いって言う人多いけど、アニメも良くない？ A lot of people say the source material is better, but isn't the anime good too?
3. 原作勢としてはこの展開知ってたけど黙ってた。 As a source material reader, I already knew this plot twist but kept quiet.
