A Japanese court has ruled that detailed written summaries of movie plots, known as "spoiler articles," constitute copyright infringement. The ruling determined that reconstructing and conveying the essence of a work goes beyond mere summarization and amounts to "adaptation," a decision expected to have significant implications for how content is consumed.
"Plot Summary Is Adaptation"... First Guilty Verdict on Spoiler Articles
According to NHK and the Asahi Shimbun on the 18th (local time), the Tokyo District Court sentenced a 39-year-old site operator, identified as A, to one year and six months in prison, suspended for four years, and fined him 1 million yen (approximately 9.29 million won) on charges of violating copyright law.
From 2018 to 2023, A posted detailed articles summarizing the plots and scene developments of movies and animations on his site and earned advertising revenue. According to prosecutors, his advertising revenue in 2023 alone reached 38 million yen (approximately 350 million won).
The content in question involved articles related to "Godzilla Minus One" and "Overlord III." The "Godzilla Minus One" article ran over 3,000 characters, describing the film's entire development from beginning to end, while the "Overlord III" article even included major lines of dialogue transcribed verbatim.
The central issue in the trial was "how far plot descriptions are permitted."
The defense argued that "merely introducing a plot in writing does not allow readers to feel the essence of the original work, and therefore cannot be considered adaptation."
The court's judgment, however, differed. Judge Jun Shimato ruled that "it can be viewed as the creation of another work in which the essential characteristics of the original can be felt based on the original," determining that the spoiler articles themselves constitute "adaptation."
"Reading Alone Equals Watching the Film"... The Court's Infringement Standard
The court emphasized that the articles went beyond simple summaries.
According to the ruling, the articles in question reproduced characters, event sequences, major scenes, and dialogue in detail.
The court ruled that "merely by reading the article, one can clearly grasp the scenes and development as if having watched the film directly,"
adding that "this conveys the essential characteristics of the original work." The court also pointed out that "this causes copyright holders to lose the opportunity to receive fair compensation and risks impeding cultural development."
Generally, adapting a movie or novel as a secondary creation requires permission from the copyright holder and payment of royalties. This case became problematic because content effectively at the "adaptation level" was produced and distributed without authorization.
The court particularly criticized the commercial intent, stating that the defendant "advanced a self-serving and arbitrary interpretation of copyright for the purpose of advertising revenue."
Meanwhile, "fast movies," which compress films into short videos, have also previously received guilty verdicts for copyright infringement.
