Shinjuku appears as a working landscape where police investigations and criminal enterprise occupy the same commercial terrain. A raid brings officers out of an office building carrying boxes of documents; nearby, consumer-finance businesses present themselves as licensed firms while feeding a wider network of lending, property, and money laundering. The district’s significance lies in this overlap: it is both a place where investigators pursue Kajiyama’s operation and a setting where that operation takes on the appearance of ordinary business.

Offices, raids, and reporting

When a press-club colleague sent Jake Adelstein to photograph a police raid in Shinjuku, he saw eleven plain-clothes officers emerge from the building with boxes of documents. The photographs were blurry, but the scene marked a major step in the investigation. Adelstein was there as backup, with no responsibility for producing a story, yet the operation rekindled his interest in Kajiyama and the empire he had built.

The raid connects Shinjuku to the practical work of reporting: arriving at a scene, recording what can be seen, and trying to establish what the paperwork might reveal. Adelstein later searched property deeds for a building mentioned in a newspaper report about a Buddhist group leader whose name had allegedly been used without her knowledge as a mortgage guarantor. The documents he had did not identify the property. He also tried to obtain a deed for Kajiyama’s monthly 900,000-yen apartment in Minato-ku, but because it was rented, no property information was available. These unsuccessful searches show the limits of tracing an operation through real-estate records, even as the surrounding investigation advanced.

The commercial face of the lending network

In Shinjuku, SK Finance looked much like Promise, a consumer-loan company listed on the Tokyo Stock Exchange. Its name stood out against a blue background, and its government license was displayed as proof that it was authorized to operate. The company had received a Tokyo government rating for consumer-loan businesses, despite the fact that such firms had largely been permitted to operate without a substantial background check. The appearance of official legitimacy was not incidental: the license made a front for Kajiyama’s network look like a conventional lender.

SK Finance also operated as a real-estate business. That arrangement let the same enterprise lend money and take property as collateral; if a debtor defaulted, the property could be seized and sold without an outside middleman sharing the profit. Leasing and renting added further business to the same structure. Shinjuku therefore housed more than a storefront for loans: it was one point in a system that linked credit to control over property.

The network extended beyond the finance office. Most of Kajiyama’s front companies used the initials SK, including SK Housing and SK Finance. Employees at loan-sharking shops were expected to buy lunches from SK Shokuhin, while managers were directed to spend money at a cohort-owned Korean barbecue restaurant and at designated hot springs and beach resorts. In the account of the operation, these compulsory purchases and outings were not merely workplace routines: money generated at one part of the network was circulated through businesses tied to another. Shinjuku’s finance and housing offices belonged to this wider arrangement of linked companies.

A map of an elusive enterprise

Adelstein went to an SK Housing branch in Shinjuku hoping to find a company brochure bearing Kajiyama’s photograph, but the office appeared to have closed. At another of Kajiyama’s real-estate agencies near the station, staff readily helped him look for an apartment, despite his being a foreigner. Their assistance produced a plausible rental option above a pachinko parlor, but not the evidence he sought: there was no brochure with Kajiyama’s image. The encounter placed the ordinary service of finding a home beside the reporter’s attempt to make the network’s leadership visible.

This contrast recurs in the Shinjuku material. The businesses could display licenses, rent office space, offer loans, and help customers find apartments; those recognizable services also formed parts of an enterprise that used employees, property, and affiliated businesses to move and launder money. Shinjuku is not presented as the whole of Kajiyama’s operation, nor does the evidence establish that every office there remained open. Instead, its offices and raid scenes provide a localized view of how the empire worked: the same streets could support investigation, legitimate-looking commerce, and the machinery of organized crime. The district’s narrative force comes from that proximity, not from any single dramatic landmark.
