NPA’s 2001 Confidential Report on the Goto-gumi

The NPA’s 2001 Confidential Report on the Goto-gumi is a top-secret assessment of Tadamasa Goto’s organization whose importance lies both in what it records and in how Jake Adelstein obtains and uses it. Compiled by the National Police Agency with assistance from police organizations throughout Japan, the report gives Adelstein a detailed account of the organization’s methods. It becomes more than background intelligence: its description of coercion and internal control helps explain why members might fear Goto, resent him, and eventually become sources against him.

Origin and Acquisition

Adelstein says he assembled hundreds of pages of material on the Goto-gumi, using techniques he had learned at the Yomiuri and accepting moral compromises to get information. Among the material was the report, which a valuable source passed to him in exchange for services rendered. The book does not identify the source in this account. Its description of the exchange matters: the document reaches Adelstein through a personal relationship and an obligation, not through an official release or an openly acknowledged police briefing.

The report’s breadth is signaled by its nationwide institutional origins and by the range of practices it describes. It was not simply an account of a single attack. It mapped procedures for planning reprisals, intimidating witnesses and the media, and keeping members in line. The account therefore gave Adelstein a framework for reading the organization as a system whose violence, concealment, and internal discipline reinforced one another.

The book places this report among very different kinds of documents that shape police and journalistic work. New reporters receive a manual and collections of example articles; a former supervisor circulates a memo on the practical demands of the police beat; and a National Police Agency directive later instructs officers to make serious efforts against human trafficking and to care for victims. Those documents have different purposes and audiences. The confidential report, by contrast, is presented as an internal assessment of a criminal organization, and its details expose the distance between official knowledge and the danger faced by people caught within that organization’s reach.

Retaliation and Concealment

The report describes reprisals as deliberate operations planned over extended periods rather than as spontaneous acts. It notes a division of roles, including preliminary inspection, the attacker, and a lookout. Responsibility was concealed so that those carrying out a reprisal would not necessarily know who had ordered it, making an investigation that reached beyond the immediate participants difficult. The report also records the use of passenger vehicles bearing license plates stolen from outside the prefecture, another measure intended to frustrate efforts to trace an offense.

Its account also describes the pressure exerted on witnesses. Members were willing to use extreme measures in the presence of women or children, with the aim of making those who witnessed violence reluctant to file criminal complaints afterward. The report’s significance is not only that it records threats; it explains how intimidation could obstruct the later processes of reporting and investigation. Violence and concealment appear as linked parts of a method.

The assessment separately identifies intimidation of the mass media as a characteristic of the organization. Members could invoke the group’s name and power to threaten people responsible for unfavorable coverage, and the report characterizes those threats as serious and persistent. That finding gives institutional weight to the danger surrounding Adelstein’s own reporting: hostile coverage was not merely a source of friction but a recognized target of organized pressure.

Discipline Inside the Organization

The report’s account of internal control describes a combination of rewards and punishment. Rewards could include help with family living expenses, improved standing after prison, cash, or gifts such as cars. These were not incidental benefits in the assessment; they were part of the means by which Goto kept members in line, tying loyalty and status to material assistance and organizational recognition.

The other side of that arrangement was demotion and punishment. When an individual’s criminal activity caused trouble for the organization, Goto could lower that person’s standing. To make an example of a member, he could beat the person in front of peers or require those peers to administer the punishment. The report thus presents discipline as both personal and collective: members could be punished before one another, and the group itself could be made to participate in enforcing obedience.

That description connects to the human consequences of Goto’s methods. One of his soldiers, who had been forced to harm a friend, approached Adelstein. The soldier disliked the reporter but hated Goto more, and became one of Adelstein’s sources. The report did not itself identify this informant in the account presented, but its description of punishment helps explain the pressures behind such a reversal. The same system designed to hold members in place could deepen their hostility toward the person exercising control.

Role in the Investigation

The report gave Adelstein a detailed basis for understanding the Goto-gumi while he pursued information about Goto and his associates. By 2006, even before he began working with Shibata, Adelstein suspected that Goto and three associates had received liver transplants at UCLA. The report should not be confused with proof of those transplants: the account identifies it as evidence about the organization’s methods, while the transplant suspicion arose through Adelstein’s broader investigation.

Its investigative value becomes clearest alongside the sources that follow. After explaining Goto’s methods of control, Adelstein describes how a soldier approached him because of his hatred of Goto; later, Shibata’s information and other organizational sources helped advance the reporting. The report did not end the investigation or make the organization transparent. It supplied a map of coercion and vulnerability, helping Adelstein understand both why information was difficult to obtain and why a person inside the group might decide to provide it. As a confidential document, it turned the police’s accumulated knowledge into a tool for a reporter working to expose the power structure it described.
