Akio Kudo The Underworld Fixer Reveals His Identity and the Pride He Holds in the Gray Zone

A Life Where the Public and Private Worlds Intersect

The legendary negotiator of the gray zone.

This is perhaps the best way to describe the life of Akio Kudo, who graduated from one of Tokyo’s six leading universities, worked at a major advertising agency and a foreign consulting firm, and then reinvented himself as the “Emperor of the Loan-Sharking Underworld.”

Born in Kumamoto Prefecture, Kudo attended one of Kyushu’s top academic high schools before entering Meiji University. In the late 1990s, when university event-organizing circles were enjoying their heyday, he made a fortune as an event promoter.

In the early 2000s, he became a driving force behind the loan-sharking boom, operating out of Kabukicho. During his time in advertising, he earned an annual salary of around ¥10 million. By the time he left the foreign consulting firm, his annual income had climbed to nearly ¥30 million. Yet in his late twenties, he casually abandoned his elite career and went on to navigate the boundary between the legitimate and criminal worlds, relying on his own distinctive instincts.

On October 8, Kudo released Tokyo Dark Dream (Kodansha), a new book in which he recounts his life story for the first time.

Why has a man who long avoided the public spotlight chosen this moment to reveal his past?

“I was never particularly interested in the underworld to begin with. What I wanted was to master the dark world where the legitimate and illegitimate intersect—in other words, the gray zone. The underworld is a place where delinquents, information, and money converge, creating business opportunities. I thought that what I had experienced and learned in the gray zone could also be useful to businesspeople in the wider world.”

Kudo’s first connection to the “underworld” came through an event-organizing circle he joined at university. He took charge of everything from planning events and securing venues to attracting female attendees and negotiating with corporate sponsors.

“A major breakthrough was securing Velfarre, a large nightclub that once stood in Roppongi. It cost ¥1.25 million per event, and everyone hesitated at the price. But I managed to raise the money and put on the event, earning the venue’s trust.

The attendees included students from prestigious universities such as Waseda, Keio, and Hitotsubashi, along with female students who came hoping to meet them. Eventually, well-known companies that wanted to recruit these students began sponsoring our events. At our peak, we sometimes raised as much as ¥80 million. While organizing events, I also became acquainted with chiimaa street gangs, motorcycle gangs, and yakuza who came to the VIP sections in search of women.”

Despite Japan’s severe employment ice age at the time, Kudo leveraged the skills he had developed through event promotion to land a job at a major advertising agency. He later moved into foreign consulting. While still working as a consultant, he had already begun operating a high-interest loan-sharking business that would later become a major social issue.

The October 9 issue of FRIDAY, covering October 23–30, along with its paid edition, FRIDAY GOLD, features Kudo’s account of the loan-sharking business that generated enormous profits, as well as his revelations about the background to the widely publicized “Petit Angel case.”
