二次創作

• 読み: にじそうさく
• ローマ字: niji sousaku
• 漢字の分解: 二 (two/second) + 次 (order/next) + 創 (create) + 作 (work) → secondary/derivative creation
• 発音: /ni.dʑi.soː.sa.kɯ/

意味

Fan-made derivative creative works based on existing anime, manga, games, or other media — fanfiction, fan art, and fan comics.

二次創作 (literally 'secondary creation') encompasses all creative works that fans produce based on existing intellectual properties. This includes fan manga (doujinshi), fan fiction, fan art, fan games, and fan music. Japan has a unique culture of tolerance toward 二次創作, with many creators and publishers tacitly allowing it as long as it doesn't compete commercially with the original.

起源と歴史

The term emerged from Japanese copyright and creative discourse, distinguishing 一次創作 (original creation) from 二次創作 (derivative creation). It became standard vocabulary in otaku communities by the 2000s as doujin culture expanded.
