Kazushige Mogi

Kazushige Mogi is a police public-relations officer and former police-academy classmate of Kyoichiro Kaga. In the Shinkoiwa murder investigation, he applies his experience with journalists and media organizations to a personal mystery surrounding Kaga: how the victim had obtained Kaga’s address years earlier. Mogi’s contribution is practical as well as interpretive, tracing a route through a published interview and the people who had handled requests for Kaga’s contact details.

Identity and Career

Mogi and Kaga attended the police academy in the same year, but their careers diverged. Kaga remained on investigations, while Mogi rotated through several precincts before settling in the public-relations department. His work brought him into contact with journalists and other media figures, whom he briefed on accidents and crimes rather than investigating perpetrators or victims directly.

That difference in professional experience shapes Mogi’s place in the case. He is not presented as a rival investigator: Kaga turns to him because media inquiries and access to a publisher require a different kind of approach from ordinary detective work.

Connection to Kaga’s Case

Mogi learns that he has an indirect connection to the Shinkoiwa victim. When Kaga’s mother died about a decade earlier, the victim had supplied the woman arranging the funeral with Kaga’s contact details. Kaga had moved repeatedly after leaving home, and his father said no one had asked him for the address. Kaga had therefore long wondered how it had reached a stranger.

The magazine interview offered a possible link. Shortly before his mother’s death, Kaga had been featured in a kendo magazine after winning the national police championships in judo and kendo. Although the magazine did not print his address, he had given it to the publisher so that a complimentary copy could be sent to him. He had considered asking whether the publisher later disclosed the address, but did not want to use his rank to pursue a personal matter. Mogi recognizes this restraint as characteristic of Kaga, who believed in doing things properly.

Kaga asks Mogi for help because an inquiry openly tied to a murder might make the publisher guarded. Mogi’s public-relations background gives him a way to approach the issue without immediately exposing the investigation’s purpose.

Investigative Work and Method

Mogi and Kaga follow a list supplied by Health Publishing Research, visiting companies in central Tokyo and continuing their inquiries into the evening. Their search takes them to Yokohama, where a journalist covering the city’s professional baseball team admits that he had asked the research company for Kaga’s contact information. The request had not been for the journalist himself, but as a favor to a female friend who worked in arts and entertainment journalism. He could not recall why she wanted the information.

The detectives contact the woman and arrange to meet her. When Mogi speaks with her, he presents the inquiry as a survey of the effectiveness of the Tokyo Metropolitan Police’s public-relations outreach. He explains that they are reviewing selected magazine and newspaper articles from the preceding twenty years and places the kendo magazine on the table, opened to Kaga’s interview. This framing lets him ask who had requested Kaga’s details without beginning with the murder connection that might have made the intermediary reluctant to answer.

Character and Narrative Role

Mogi’s work is marked by patience with indirect routes. He describes the search as a succession of dead ends, but sees value in persistence: even a small foothold can make the frustration worthwhile. The investigation turns on just such a foothold, moving from Kaga’s old magazine feature to a journalist, then to the female journalist who had sought his contact details.

His role also brings the case’s private and institutional strands together. The address was connected to Kaga’s mother’s funeral, while the route by which it was obtained ran through a publisher and media contacts. Mogi helps investigate that route without confusing his public-relations duties with the detective work itself. His contribution is not a final resolution in the available account, but a carefully managed step toward identifying how the victim came to possess information about Kaga.
