Two of Japan’s largest media firms are seeking billions of yen in damages from AI search engine Perplexity and raising once more questions of how news content is being used by artificial intelligence platforms.
Nikkei and The Asahi Shimbun jointly sued Perplexity in Tokyo District Court for ¥2.2 billion ($15 million) in damages each. The publishers are also asking for an injunction against the AI firm to desist from using their content and erase all stored articles from their publications.
What is Behind the Legal Challenge
Perplexity AI Sued Over Copyright Infringement and Misinformation
The crux of this controversy is charges that Perplexity has been copying, archiving, and duplicating news articles from both news outlets without authorization since at least June 2024. But it is not just copying the media companies charge that Perplexity is actually evading technical protections designed to prevent unauthorized access.
These protections, known as robots.txt files, are like digital “no trespassing” signs that websites use to tell automated systems which parts of their content should be off-limits. The lawsuit alleges that Perplexity ignored these barriers and scraped content anyway, violating both Japanese copyright law and the country’s Unfair Competition Prevention Act.
“This is mass-scale, repeated free riding on article content,” the publishers say, adding that reporters are not paid for their work to be used in this fashion.
In addition to their copyright issues, Nikkei and Asahi are more concerned with the way they are represented on Perplexity’s website. They assert that the AI system generates false summaries but continues to cite their publications as sources, thereby creating the dangerous scenario of false information bearing the credibility of their respected brand names.

This is not merely a matter of defending intellectual property this is a matter of defending the integrity of journalism. When AI systems mislead or inappropriately reduce news content, it can compromise public confidence in genuine news sources and disseminate misinformation, the publishers caution.
The concern extends to the economic foundation of the broader news industry. If AI websites can provide brief summaries of news articles, there will be fewer people who visit the original sources, and this may cut into the streams of income that underwrite professional journalism.
The Rising Tide of AI Copyright Lawsuits and Perplexity’s Legal Battles
Perplexity has not made any public statement regarding this specific lawsuit, even though the company has previously defended itself when faced with such legal challenges in the United States. Perplexity maintains that its search engine gathers content in real-time to answer user queries rather than keeping vast amounts of publisher data.
In the background of increased tensions with news organizations, Perplexity recently announced a $42.5 million revenue-sharing plan for paying publishers whose material is used on its site. This Tokyo lawsuit, however, indicates that that will not be enough to appease all media organizations.
This court case is not an isolated incident. Other large Japanese publishers, such as Yomiuri, have also brought similar suits, and international media giants such as Dow Jones have also sued AI platforms for rights to use content.
AI vs. Journalism: The Copyright Conflict and the Future of Information
The episode illustrates a fundamental conflict of the digital technology era: AI firms contend that in order to train their algorithms and offer useful services, they require access to enormous quantities of data, but content creators desire to have control over the usage of their work and just compensation for its worth.
The decision of this case can potentially make significant precedents on the legal use of copyrighted material by AI firms, especially where technical constraints are concerned. Although Japanese law permits copyright material to be used to train AI under certain conditions, it does not permit reproduction and storage in a direct sense without permission.
As artificial intelligence improves and broadens in search and summarization, the way cases such as these are resolved will most likely decide the future of artificial intelligence and the coexistence of journalism. It’s not a matter of dollars and cents, it’s a matter of whether or not traditional media can coexist with AI technology and continue to be valid sources of information.
