Saitama Prefecture is where Jake Adelstein’s reporting moves from the metropolitan newsroom into a demanding regional beat, and where several investigations expose the distance between a missing-person report and the criminal history behind it. Urawa, Chichibu, Kumagaya, and Konan are not interchangeable backdrops: each marks a different point in the work, from the routines of a local bureau to a homicide investigation and the recovery of a forgotten case. Together, they make Saitama the book’s working landscape of local knowledge, investigative access, and the consequences of publishing too soon.

The regional beat

Jake Adelstein was assigned to the Yomiuri’s Urawa office after an initiation period in which new reporters could be given jobs such as layout before joining the reporting roster. Matsuzaka described Urawa as a Spartan office in the heart of Saitama, where Adelstein would have many chances to write for the national edition and would be extremely busy. The assignment was geographically close to Tokyo, but Matsuzaka warned that once Adelstein was there, the capital would feel far away. The contrast defines the regional beat: proximity did not mean an easy commute back into the center of the newspaper’s world, but a full workload rooted in Saitama.

That distance also gave the bureau its own investigative importance. Reporting there meant learning how to gather information beyond the routines of the metropolitan police beat. Adelstein’s work depended on conversations with residents, local officials, and sources inside the police, and on following leads across small towns where the social standing of a suspect could differ sharply from what an outsider might expect. The region’s significance lies partly in this change of scale: a case that appeared peripheral from Tokyo could become a major investigation once local details connected it to older disappearances.

Chichibu and the murder investigation

In Chichibu, police declared the death of a snack-bar proprietor a murder and established a special investigation headquarters. The Chichibu Snack Bar Proprietress Murder Case began with a missed shift. The woman normally went to work at five in the afternoon, but when she failed to appear, one of the hostesses went to her apartment. After receiving no answer at the locked door, the hostess asked the building manager to open it with a key.

The apartment appeared orderly, with no apparent sign of a struggle or burglary and nothing evidently stolen. The proprietor was found dead on her futon. The discovery made the case an immediate focus for police and reporters, but the ordinary details of the initial search mattered too: the concern of a coworker, a locked door, and the manager’s key brought the investigation into a private home rather than a public scene. Adelstein received information from Yamamoto, who relayed what he had learned at a briefing, showing how reporting on Saitama cases relied on access to the police process as it developed.

Kumagaya and a case recovered from neglect

A later investigation began with a dog breeder near Kumagaya, Gen Sekine, who was suspected of being a serial killer. In the preceding ten years, several people associated with him had disappeared. Police had investigated the first three disappearances, but the leads ran out and the case faded from attention. The renewed inquiry followed the disappearance of Akio Kawasaki, the president of a waste-management company. When Kawasaki’s wife reported him missing, the initial police questions focused on familiar explanations: unusual behavior, domestic problems, unexplained absences, or enemies.

Her mention of a disagreement between her husband and a dog breeder changed the tone of the questioning. The officer warned her to prepare for the worst if Kawasaki had been involved with Sekine, and police reopened the old case. Two months after Kawasaki disappeared, the Saitama police homicide division formally established a special task force. Ten detectives were working on the inquiry by the time Nakajima’s source brought him into the loop. The source said that the Yomiuri could wait for an exclusive and that even senior Saitama police officials did not yet know the details, making an early leak to other papers less likely.

The reporting also depended on archival work. Adelstein was asked to search the newspaper’s old files for information about Sekine or his pet shop, African Kennel. The Yomiuri had not yet digitized its back issues, so he searched through physical scrapbooks. After two days, he found a July 14, 1992, story about a Kumagaya pet breeder who had raised a lion on his balcony; the article reported that the animal would be sent to a zoo in Gunma Prefecture. The discovery gave the investigation a specific connection to the past, though the reporting’s publication had an immediate cost: it alerted Sekine that police might be investigating him and risked encouraging him to destroy evidence.

Konan and the search for local knowledge

After the article appeared, Adelstein traveled to Konan to learn more about Yasunobu Endo, whose disappearance was connected to the investigation. He described the town as a place with one large Zexel factory, a golf course, town hall, three schools, a grocery store, a family restaurant, and extensive open fields. It also had a temple devoted to Monju, the Buddha of Wisdom. Adelstein could not find a recognizable downtown. The description places the reporting in a sparsely populated setting where institutional landmarks and personal memories mattered more than a conventional urban center.

Rather than begin by pressing police officers, Adelstein made inquiries at the fire department, whose members he had found more willing to talk. He learned that Endo had been the number-two man in the Takada-gumi, a third-tier group in the Inagawa crime family. Yet the people he encountered did not speak of Endo only with fear or deference. They remembered him as a former truck driver and a man they had supported in a mayoral election; one firefighter said he had voted for him in 1984. Their concern for Endo’s welfare complicated the simple image of a feared gang figure and gave the reporter a local account that official labels alone could not provide.

Police access and criminal networks

The Saitama investigations also reveal how access between police and organized crime could be indirect and politically delicate. During the inquiry into the missing people associated with Sekine, the Yomiuri’s early publication alienated the police. Investigators believed the story could have tipped Sekine off, while senior officers held the paper responsible if evidence was lost. The conflict was not simply between reporters and officials over a story; it affected the conditions under which the investigation could proceed and the willingness of police sources to share information.

The region also appears in a broader account of organized crime’s business activity. Kaneko described protection money from the sex industry in Omiya as one part of the Sumiyoshi-kai’s revenue, alongside land-related schemes, illegal waste disposal, extortion, and front companies. He portrayed the organization as an economic network that could profit from information, property, debt, and commercial services, not merely as a group defined by violence. A source who heard Kaneko’s account suspected that the disclosure might reflect an internal power struggle, illustrating how information about criminal enterprises could itself become part of a contest within an organization.

Across these episodes, Saitama is both a reporting assignment and an investigative system of relationships. Police task forces, local witnesses, archival records, and organized-crime sources each reveal different parts of a case, while the timing of a newspaper story can either secure public attention or damage cooperation. The prefecture’s narrative importance comes from that tension: its local scale makes older connections visible, but the same visibility can warn suspects and strain the networks on which an investigation depends.
