(JR East) as 'experimental sites to create enriching lives for the next 100 years.' The championship was organized by JR East with the aim of allowing people to imagine future infrastructural management, while seeking to improve drone operation technology and safety. Many of the company's departments have introduced drones in their work.By Ryuzo Suzuki / Yomiuri Shimbun Senior PhotographerA drone with lights dashes inside a pipe in a space modeled after an underfloor space on the second day of the championship.The inter-department tournament between four teams from JR East was held on June 7; the inter-company tournament between eight teams from companies collaborating with JR East, such as a security firm and an electric power company, took place on June 8.

Participants navigated drones remotely by hand, relying only on images sent from the drones to clear the tricky challenging sections modeled after train station facilities, such as attics, underfloor spaces and platforms, before crossing the finishing line at a real automatic ticket gate. The win was not counted unless the drone tapped the automatic ticket gate with a Suica IC travel card attached to its body.
The competition was a single-elimination tournament. Each team of three took turns racing the course, with total team time as the deciding factor for the winner.

Yomiuri Sues U.S. AI Startup over Use of Articles; Perplexity Allegedly Used Over 100,000 News Stories

Three Yomiuri Shimbun newspaper companies have filed a lawsuit against a U.S. startup company that allegedly used a large number of Yomiuri Shimbun articles and images for a generative AI-powered search engine without permission. The Yomiuri Shimbun; The Yomiuri Shimbun, Osaka; and The Yomiuri Shimbun, Seibu filed the lawsuit demanding that Perplexity AI, Inc. stop using the newspaper's articles and seeking damages of about ¥2.17 billion in the Tokyo District Court on Thursday. The three companies are under The Yomiuri Shimbun Holdings. This is the first time a major Japanese media company has filed such a lawsuit, although several AI-related businesses in Europe and the United States have been taken to court for the unauthorized use of copyrighted material by generative AI. Established in 2022, Perplexity provides a search service that parses the latest online information to compile answers to questions typed in by users. A conventional search engine will display a list of websites related to the search terms entered by a user, but Perplexity pitches its service as an 'answer engine' that summarizes information gleaned online. This enables users to acquire information they want without looking through individual websites. In its lawsuit, The Yomiuri Shimbun claims that Perplexity copied articles from the Yomiuri Shimbun Online (YOL) digital service and sent answers with content similar to these articles to its users. The Yomiuri Shimbun claims this violated the right of reproduction and the right to public transmission under the Copyright Law. Perplexity allegedly acquired 119,467 Yomiuri articles without permission between February and June this year for the purpose of generating answers for its users. The Yomiuri Shimbun decided to seek damages of ¥16,500 per article, calculated based on a regular licensing fee. The amount of compensation being sought could increase depending on the findings of a further investigation. In addition, conventional search engines encourage users to visit the YOL service, which generates advertising revenue for The Yomiuri Shimbun. However, Perplexity's service results in fewer online visits to the YOL. The Yomiuri Shimbun claims that this is causing a drop in advertising revenue, which also constitutes an infringement of its business interests. About 2,500 reporters are involved in news coverage for The Yomiuri Shimbun. Consequently, the newspaper believes Perplexity has been getting a 'free ride' on the activities of a media organization that devotes 'great effort and expense' to creating news articles. The Yomiuri Shimbun also is seeking compensation for lost advertising income. In response to The Yomiuri Shimbun's emailed request for comment, Perplexity sent a message that said: 'We are deeply sorry for the misunderstanding this has caused in Japan. We are currently working hard to understand the nature of the claims. We take this very seriously, because Perplexity is committed to ensuring that publishers and journalists benefit from the new business models that will arise in the AI age.' In October 2024, Dow Jones, a division of News Corp., filed a lawsuit together with another company alleging copyright infringement by Perplexity. That case is pending in federal district court in New York. Perplexity has rejected the claims in that case and insists that its search function is based on publicly available facts that are not protected by copyright laws. Yomiuri warns of negative impact The Yomiuri Shimbun Holdings' Corporate Communications Department issued a statement that said: 'Allowing a company to free ride on the results of our reporting would negatively affect our accurate news coverage backed by our research, and could undermine the foundations of democracy. We hope this lawsuit will raise questions about rules on the rapidly spreading use of generative AI and how it should be used and applied.'

Yomiuri Shimbun Sues U.S. AI Firm for Copyright Infringement

News from Japan Aug 8, 2025 17:57 (JST) Tokyo, Aug. 8 (Jiji Press)--The Yomiuri Shimbun has sued U.S. artificial intelligence-powered search engine Perplexity at Tokyo District Court for alleged copyright infringement of the major Japanese newspaper's articles, seeking a total of some 2,168 million yen in damages. The newspaper's three headquarters, located in Tokyo, Osaka and Fukuoka, also demanded a ban on the U.S. startup from using the newspaper's articles. This is the first lawsuit filed by a major Japanese news organization against a generative AI company over the use of news articles, according to the Yomiuri Shimbun side. In its complaint, the Japanese newspaper claims that Perplexity, which answers users' questions in summarized texts and images after collecting information using its AI-powered search engine, obtained and reproduced information from 119,467 online articles without permission between February and June. The newspaper group issued a statement saying that tolerating a free ride on articles could negatively affect accurate news reporting. It also said that the lawsuit is intended to seek a court judgment on the discipline and use of AI as this state-of-the-art technology is being rapidly adopted.

Major Japan newspaper sues 'free-riding' AI firm Perplexity

Japan's Yomiuri Shimbun newspaper, one of the world's biggest by circulation, is suing U.S.-based AI firm Perplexity for allegedly "free-riding" on its content on its search engine. The lawsuit filed Thursday is one of a slew by media companies worldwide against AI firms using their material and is the first by a major Japanese news organization, Yomiuri said. It accuses Perplexity of "free-riding on the results of the activities of news organizations, which have invested a great deal of effort and expense." A spokesman for the paper added that this "could have a negative impact on accurate journalism ... and shake the foundations of democracy." The lawsuit filed in Tokyo seeks damages of ¥2.2 billion ($14.7 million), equivalent to 120,000 Yomuiri articles used "without permission" between February and June. It is also seeking damages for lost advertising revenue, saying that Perplexity users click only on its search summaries and not on the newspaper's website, reducing traffic. The Yomiuri, with a daily circulation of around 6 million — down from over 10 million in 2010 — and some 2,500 reporters, is one of five major daily newspapers in Japan. Perplexity was not immediately available for comment. After a lawsuit by the Wall Street Journal and the New York Post in October, Perplexity criticized the "adversarial posture" of many media as "shortsighted, unnecessary, and self-defeating." They "prefer to live in a world where publicly reported facts are owned by corporations, and no one can do anything with those publicly reported facts without paying a toll," it said. "We should all be working together to offer people amazing new tools and build genuinely pie-expanding businesses."
