Jake Adelstein—Sekiguchi mentor relationship

Jake Adelstein’s relationship with Sekiguchi is both a professional apprenticeship and a lasting personal bond. Sekiguchi helps Jake navigate the risks of reporting: he tests whether the younger reporter can be trusted, explains how information moves through police hierarchies, and warns him when an investigation may endanger its sources. Years later, Jake still seeks Sekiguchi’s judgment, while Sekiguchi’s cancer turns their relationship toward acts of care and farewell. The bond is sustained not by easy reassurance but by frank counsel, loyalty, and the wish to remain useful to one another.

Early Trust and Professional Guidance

Sekiguchi’s authority in Jake’s life grows from the period when Jake was a young reporter in Saitama Prefecture. A later visit makes the length of their association explicit: ten years had passed since Jake began reporting there, yet Sekiguchi remained his mentor, and his family treated Jake as one of their own. The relationship had outlasted Jake’s first assignment and become part of his continuing connection to Japan and to the work of reporting.

Their trust was not automatic. In one early meeting, Sekiguchi listened as Jake described his background and how he had entered the Yomiuri Shinbun. He then praised Jake’s approach to getting through the door, while making clear that the remaining question was whether he could be trusted. This scrutiny gives their later closeness a practical foundation: Sekiguchi does not simply welcome Jake but assesses his judgment and intentions.

Sekiguchi’s advice includes more than the acquisition of information. He cautions Jake that ground-level knowledge may not yet have reached senior officials. If Jake checks such information too soon with people at the top, they may trace it back down the chain and identify the person who supplied it. The lesson is to wait for information to travel upward before verifying it, so that a source is not exposed. Sekiguchi thus teaches Jake to think about the path information takes, and about the people who bear the cost when a reporter handles it carelessly.

A Working Relationship Built on Candor

The mentorship develops alongside Jake’s investigations rather than apart from them. In one exchange, Jake relays what he has heard from Kaneko to a source, who suspects a power struggle inside Kaneko’s organization and explains how police assigned to organized-crime work obtain information. Such exchanges show the investigative world around Jake as a network of partial knowledge, careful access, and guarded cooperation. The evidence does not make every source in that network identical, but it echoes the method Sekiguchi teaches: information must be tested with attention to who knows it, when they learned it, and what confirmation might reveal about its origin.

The relationship also carries direct consequences for an investigation. After Jake’s information reaches a source, Takada contacts that source and says he has Sekine in custody, offering a chance to listen to the questioning. The source declines, tells Takada not to kill Sekine, and asks to be informed of what is learned. This is a measured response to a dangerous situation: the source does not take up the invitation, but uses the relationship to set a limit and keep track of the investigation. The exchange reflects the kind of judgment Sekiguchi’s guidance encourages, even as it shows how close reporting can come to coercive power and physical danger.

Home, Family, and the Search for Approval

A decade after his early Saitama reporting, Jake visits Sekiguchi and his family in the north of the prefecture. The visit is domestic as well as professional. Sekiguchi and his wife welcome him, and their daughters, whom Jake remembers as small children, have grown up. Though Sekiguchi has recently been diagnosed with cancer, he is in good spirits and talks about the pleasure of returning to real detective work. His wife brings out familiar snacks, and the two men discuss a case from which prosecutors have removed Sekiguchi. The investigation has been halted for political reasons connected to the governor, a reminder that even an experienced detective’s work can be constrained by forces outside the case itself.

By 2006, Jake’s visits carry a sharper urgency. He arrives unannounced in January with a duty-free bag of tobacco and a family New Year’s card. Sekiguchi is surprised to see him, since Jake was not expected to be in Japan, but greets him warmly. The card includes Jake, his wife Sunao, and their son; the gift and the family photograph bring Jake’s life outside reporting into the friendship. Their reunion is not merely a check-in between a reporter and a former source. It is a return to someone whose recognition Jake values.

After accepting a new reporting opportunity, Jake comes back to Japan before the year is over and makes a point of seeing Sekiguchi. He has made his decision without consulting others, and later recognizes that he wanted Sekiguchi’s approval more than his advice. Sekiguchi responds with pride in Jake’s progress from a naive cub reporter, but does not turn that pride into unqualified encouragement. He asks whether Jake will keep his family in the United States while he works in Japan, placing the risks of the new assignment in the context of Jake’s obligations to those closest to him.

Warnings About the Work

Sekiguchi’s warnings grow more pointed as Jake’s reporting moves toward the sources of organized crime’s money. He distinguishes familiar stories about gang wars, tattoos, and sexual exploits from investigations into the businesses and revenue streams behind the organizations. Human trafficking, child pornography, and prostitution are described as profitable criminal enterprises; exposing those sources of income, he warns, threatens the business itself. His concern is not an abstract caution against difficult reporting but a specific assessment of what could provoke retaliation.

He also tells Jake that, as far as Goto is concerned, Jake is an ex-reporter, and that this appearance may offer some protection only so long as Goto does not learn about the new work. Tokyo is Goto’s territory, Sekiguchi cautions, and Jake will be asking questions there without permission. He urges Jake to be careful about whom he calls, meets, and speaks to. Jake understands the warning but resists the implication that he is still an inexperienced reporter. He believes he knows what he is doing, while acknowledging that he may only think so. The difference between confidence and certainty remains unresolved between them.

Sekiguchi’s final counsel in this period returns to their decade-long bond. He says he is proud to know Jake and believes the work is important, but emphasizes that investigating sexual slavery will bring Jake into conflict with powerful interests. He tells him to keep in touch, pats him hard on the shoulder, waits for him to get into a taxi, and bows goodbye as the family comes out to wave. The gestures make the warning personal: Sekiguchi is not only assessing a story’s danger but asking Jake to protect himself and the people he cares about.

Illness and Reciprocal Care

As Sekiguchi’s cancer advances, the balance between mentor and protégé begins to change. He tells Jake that chemotherapy has left him too sick to work on some days, though he continues going in almost every day. Doctors estimate that he may have a year or two. The prognosis gives new weight to Jake’s return visits and to his desire for approval; the mentor who once judged Jake’s professional readiness is now someone Jake may be losing.

Treatment requires Sekiguchi to travel from his home in Saitama Prefecture to the Ariake Cancer Institute in Odaiba, sometimes making the long journey back by train after chemotherapy and radiation. Jake insists on paying for him to stay at the nearby Grand Pacific Le Daiba hotel after treatment. Sekiguchi refuses at first because he is still a police officer and does not want to accept something of monetary value from Jake. Jake tells him that a company he works for owns the hotel and that the room is complimentary. The claim is a lie, and Jake believes Sekiguchi understands that it is one. Their shared understanding lets Sekiguchi accept the room without openly violating his sense of propriety. Jake frames the deception as a practical kindness: a way to give his mentor a chance to rest while allowing both men to preserve the appearance that makes the gift acceptable.

The relationship therefore moves beyond a one-way transfer of professional knowledge. Sekiguchi continues to give Jake warnings and recognition; Jake, in turn, tries to relieve the strain of treatment and to honor Sekiguchi’s dignity. The available account does not resolve their story with Sekiguchi’s death or a final separation. Instead, it leaves them in an ongoing bond shaped by illness, unfinished work, and the repeated effort to stay in touch. Their mentorship endures because its care is concrete: advice about protecting sources, concern for Jake’s family and safety, a visit with a New Year’s card, and a hotel room offered through a mutually understood fiction.
