Translation

架空の / フィクションの / 物語上の

Meaning

Fictional means existing in a story, film, game, or imagined world rather than in real life. It does not normally imply fraud or lying. For a false name in an official document, fictitious or fake is usually better.

Examples

• シャーロック・ホームズは架空の探偵です。
  Sherlock Holmes is a fictional detective.
• そのゲームは架空の都市を舞台にしています。
  The game is set in a fictional city.
