The Susumu Kajiyama loan-sharking case revealed how an organized-crime enterprise could resemble a legitimate consumer-finance franchise while drawing profit from illegal lending, debt collection, and a web of associated businesses. Susumu Kajiyama’s network reached close to a thousand loan-sharking outlets across Japan, and investigators eventually pursued its money through Tokyo and Las Vegas to a Swiss bank account. His conviction brought a prison sentence and changes to lending law, though the scale of the operation and the money not recovered left the outcome far from a complete accounting.

Building a nationwide lending operation

Kajiyama, a corporate blood brother of the Goryo-kai, a subdivision of the Yamaguchi-gumi, began building his network in 2000. The Tokyo Metropolitan Police Department announced a warrant for the operation’s leader while Jake Adelstein was working a night shift. The case stood out to him not only because its target was a senior figure in the Yamaguchi-gumi, but because the police unit handling it was the Community Economic Safety Division rather than the Organized Crime Control Bureau. The alleged offense involved Japan’s Investment, Deposit, and Interest Rate Control Law.

The enterprise found customers among people with poor credit who could no longer borrow from consumer-finance companies. Kajiyama’s operation acquired databases of heavily indebted borrowers and used personal calls and email to solicit them. Its storefronts were designed to look much like ordinary consumer-loan shops: customers encountered a conventional business setting and could obtain loans that other lenders would refuse. The cost, however, could reach between ten and 1,250 times the interest permitted by law.

Repayment pressure extended beyond the borrower. Collectors could persistently contact debtors, their spouses, and their employers, using threats to demand payment. The account describes the consequences as severe: the pressure drove some borrowers to suicide. The operation’s reach was reflected in the number of people affected; investigators considered more than sixty thousand borrowers who had paid illegal rates, while police estimated the group’s revenue in the billions of dollars.

The corporate machinery behind the loans

Kajiyama’s business was not limited to lending. Its numerous fronts included real estate and construction businesses, a share in a marina, and other operations that connected the loan shops to a larger commercial network. Employees were directed to spend money within that network: shop workers had to buy lunches from SK Shokuhin, while managers were expected to dine at a Korean barbecue restaurant owned by one of Kajiyama’s associates. Organized trips to designated hot springs and beach resorts added further channels for moving funds. The purchases and arrangements were presented as routine workplace expectations, but the book describes them as ways of laundering the proceeds of the lending shops.

The network’s naming and public presentation helped it pass as ordinary business. Many fronts used the initials SK, as in SK Housing and SK Finance. In Shinjuku, SK Finance looked much like a branch of a listed consumer-loan company, displayed its government license, and held a Tokyo-issued rating for this kind of business. It also operated as a real-estate company. That combination let the group take property as collateral, seize it after a default, and sell or lease it without relying on an outside intermediary.

This structure depended on more than Kajiyama and his yakuza connections. A colleague assessing the case argued that the participation of several hundred non-yakuza workers was a more revealing part of the story than the expected criminality of the gang itself. Kajiyama’s operation used civilian employees and business services to make an illicit enterprise function at scale. Its corporate form did not conceal a single illegal activity so much as distribute the work across ordinary-looking companies, staff, and transactions.

Following the money abroad

The central investigative question became what had happened to the profits. A large share was presumed to flow to the Yamaguchi-gumi, but it did not appear in Japanese bank accounts. Kajiyama had spent time in the United States and, according to a source in Las Vegas, had lost a couple of million dollars gambling at the MGM Grand. The source also described cash held in a safe-deposit box and overseas bank accounts. An FBI contact in Washington, D.C., confirmed that Tokyo police had visited Las Vegas and seized two million dollars from the MGM Grand’s office in Tokyo.

Jake Adelstein and colleagues worked out a publication sequence with a Tokyo police division chief. Their reporting on Kajiyama’s Las Vegas activity would appear first; the Tokyo Metropolitan Police Department would then announce the seizure, followed by a rearrest on Japanese money-laundering charges. The journalists also expected to report on an FBI investigation into possible money laundering in the United States. By mid-November, a run of stories covered the cash seizure, the FBI inquiry, and Kajiyama’s Las Vegas spending. A subsequent arrest of an associate who had withdrawn more than a million dollars from Kajiyama’s account and traveled repeatedly to the United States carrying cash gave the investigation another concrete link in the financial trail.

The Las Vegas findings were only part of the picture. A few weeks later, it emerged that more than fifty million dollars had been placed in a Swiss bank account with assistance from a Japanese employee of Credit Suisse. Switzerland froze the account. The revelation eclipsed the earlier seizure in scale, but it did not resolve how much money the network had moved or where all its assets were. A further episode showed that cash remained accessible: around the time of Kajiyama’s arrest, an associate arranged for one million dollars to be delivered from a Caesars Palace representative to a parking lot in central Tokyo.

Conviction and consequences

Kajiyama did not confess during the repeated arrests and releases described in the account. On February 9, 2005, he was sentenced to seven years of hard labor. The Tokyo courts initially did not impose the five-billion-yen fine that would have equaled the fifty million dollars identified in the Swiss account. The sentence therefore left open the question of how much of the operation’s gains remained beyond investigators’ reach; the book notes the likelihood that Kajiyama still had money concealed elsewhere.

The network changed after the conviction. Kajiyama’s associates dispersed, and the Goryo-kai ceased to exist under that name. Some former associates moved into elaborate telephone scams in which criminals impersonated a victim’s child or grandchild and claimed to need an urgent money transfer. The enterprise’s form shifted, but some participants continued making money through fraud.

The case also had a legislative consequence. Japanese lending laws were revised to increase penalties for loan-sharking and to establish a clear ceiling on interest rates that legitimate consumer-loan companies could charge. The investigation thus connected an individual criminal conviction to a wider regulatory response: exposing a nationwide lending structure helped prompt rules intended to constrain both illegal lenders and the rates available to legal ones.

Significance of the case

The investigation’s distinctive finding was that Kajiyama’s operation worked through the overlap between organized crime and conventional business. Borrower databases, licensed storefronts, real-estate collateral, payroll, restaurants, travel, and foreign financial channels formed parts of a single system for generating and moving money. The case made that system visible through a sequence of local and international inquiries, from loan-shop practices to a Tokyo cash seizure, Las Vegas gambling, and the frozen Swiss account.

Yet exposure and conviction did not amount to full recovery or the end of the network’s methods. The seven-year sentence, the initially absent fine, the unidentified remainder of the money, and the associates’ later turn to telephone fraud mark the limits of the outcome. The law changed, but the case left a more difficult measure of success: not only whether Kajiyama was punished, but whether investigators could account for the wealth and dismantle the business relationships that had made the operation durable.
