非公式

• 読み: ひこうしき
• ローマ字: hikoushiki
• 漢字の分解: 非 (non-, un-) + 公式 (official, formal) → unofficial, non-official
• 発音: /hi.ko.u.ɕi.ki/

意味

Unofficial; fan-made or unauthorized content, events, or accounts that are not endorsed by the official creators or rights holders.

非公式 is an important label in Japanese fan culture, where the boundary between official and unofficial content is carefully observed. Fan-made goods, accounts, translations, and events are labeled 非公式 to avoid confusion and potential legal issues. Japan's doujin (self-published) culture means 非公式 content is massive, but fans are generally careful to distinguish it from 公式 (official) releases. Using 非公式 material without disclosure can cause fan community backlash.
