Yomiuri Shimbun Publishes the Missing-Person Story Ahead of Agreement

The Yomiuri Shinbun’s decision to publish news of the Saitama disappearances before the agreed moment was both a scoop and a breach of trust. Triggered by a sensational, inaccurate headline in the sports paper Asuka, the decision put the newspaper ahead of its competitors but warned Gen Sekine that police were investigating him. It also turned an arrangement intended to secure an exclusive at the time of arrest into a broken promise for which the police held the Yomiuri Shinbun responsible.

The Agreement and the Leak

The Yomiuri Shinbun had been receiving information from the Saitama police in exchange for keeping the investigation under wraps. The understanding, as Jake Adelstein explained at the newsroom meeting, was that the paper would sit on the story and receive an exclusive when the arrest came. This was not simply a question of timing: withholding publication was the price of continued access and a promise made to investigators.

That arrangement operated within a press system where access to official information was tightly organized. At the Tokyo Metropolitan Police Department, the ninth floor housed press clubs for newspapers, television, and radio and local newspapers. Weekly and monthly magazines were excluded, as were foreign media representatives. The Yomiuri Shinbun’s police relationships therefore mattered not only to this investigation but to the institutional channels through which Japanese reporters received news.

The immediate trigger was the appearance of an Asuka headline announcing, “Four People in Saitama Missing; Mysterious Dog Breeder Involved.” The article included a chart of the victims, though Adelstein described it as “horribly incorrect.” Even so, the information was public. As the newsroom reacted, Yamamoto put the paper in front of Adelstein and said, “The dog’s out of the bag.” The scoop had come from a sports newspaper the Yomiuri Shinbun regarded as far less credible, but its inaccuracies did not restore the possibility of keeping the investigation secret.

The Newsroom Decision

Yamamoto summoned staff to an emergency meeting at the Urawa office, scheduled for thirty minutes later. The bureau chief, Hara, and the head editor were already examining Asuka’s evening edition. Hara challenged Yamamoto: “I thought we had this thing locked up?” The staff had to decide whether the rival paper’s disclosure had made their own restraint pointless, or whether publishing would compound the damage by breaking the agreement with police.

Adelstein, a new reporter, raised his hand despite Yamamoto’s gestures urging him to stay quiet. When the editor brushed him off, Hara invited him to speak. Adelstein set out the bargain directly: “They’ve been giving us everything in exchange for us sitting on the story. When the time comes for the arrest, they’ll give us the exclusive. That was the deal.” He argued that printing now would forfeit police trust and violate the paper’s promise. The Asuka report, he added, was inaccurate and lacked credibility; a Yomiuri Shinbun article would carry a different weight. Publishing might win the immediate race for readers while sacrificing the more consequential relationship with investigators.

Hara considered the argument, studied the article, and then decided the paper could not ignore a story already in circulation. He expected the police to be upset but believed they would get over it. The meeting ended with instructions to write for the morning edition. Adelstein’s warning did not change the decision, but it had made the cost visible inside the newsroom: the choice was no longer merely whether the paper could publish, but whether it would accept responsibility for what publication might do to the investigation.

Publication and Consequences

The Yomiuri Shinbun’s first story appeared on the morning of February 19 under the four-column headline, “Several Dog Lovers Missing in Saitama from April to August. Trouble over Sales.” Because it ran in the morning, other papers scrambled to catch up after publication. The Yomiuri Shinbun had seized the lead in a case that had become nationally reportable, rather than letting the sports-paper disclosure define the coverage.

The competitive gain came with a direct investigative risk. Adelstein later judged that the article had “completely alienated the police” and must have alerted Gen Sekine that he was under investigation. Forewarned, Sekine would have less reason to reveal himself and more incentive to destroy evidence. The publication thus had consequences beyond the reporter-source relationship: it could alter the behavior of the person police were investigating and make evidence harder to preserve.

The police did not treat the Yomiuri Shinbun’s decision as an unavoidable response to Asuka. They considered the paper the first legitimate newspaper to publish news that was not ready to be known, and held it responsible if anything went wrong. The chief detective made that position clear to the paper’s editor, while Kanji Yokozawa, the head of the forensic department, placed the Yomiuri Shinbun on his personal blacklist. Their anger was specifically directed at the paper that had broken first among the major newspapers, even as others followed the story.

Significance in the Reporting Arc

The episode reveals the double edge of a scoop: publication can establish a paper’s lead while destroying the cooperation that helped make the reporting possible. Adelstein’s argument distinguished immediate prominence from long-term access, but the newsroom chose the former once Asuka had made secrecy untenable. His assignment to investigate Yasunobu Endo and his driver Wakui followed the decision; Yamamoto told him that, from the next day, his life would be Endo’s life. The story therefore began for Adelstein not with an unqualified journalistic victory, but with a new assignment under conditions worsened by the paper’s own timing.

The book later places this breach against other points where reporting is constrained by institutional or commercial pressure. When Adelstein tried to publish his investigation of Tadamasa Goto’s FBI deal, the Yomiuri Shinbun and other Japanese newspapers declined to run it, citing its age, concern about embarrassing the National Police Agency, and uncertainty about FBI confirmation. In the Saitama case, the newspaper published despite police objections because a rival had made the news public; in the later investigation, major outlets withheld a story even after Adelstein supplied it. Together, these episodes show that publication is not a simple contest between truth and silence: access, timing, institutional loyalties, and the anticipated costs of printing shape which facts reach readers.
