19 Heinously Brazen or Brutal Yakuza Crimes in Modern Times

Japan is famous for bullet trains, anime, and vending machines that sell basically everything. It is not famous for sky-high murder rates. In fact, Japan’s homicide rate is among the lowest in the world. That’s part of what makes modern yakuza crimes so shocking: when violence does erupt, it really stands out.

The yakuza, Japan’s long-standing organized crime syndicates, have been involved in everything from old-school gang wars and assassinations to high-tech ATM hacks and financial fraud. Police crackdowns and strict anti-gang laws have weakened their power and shrunk their numbers, but the legacy of their most brazen acts still looms large in Japanese politics, business, and pop culture.

Let’s walk through 19 of the most heinous, bold, or just plain terrifying yakuza crimes in modern timeswithout glamorizing them, and with an eye on what they tell us about organized crime in today’s Japan.

1. Kudo-kai’s Public Assassination and Grenade Terror

The Kudo-kai, based in Kitakyushu on Kyushu island, has a reputation even other yakuza groups consider extreme. In 1998, members openly shot 70-year-old former fisherman and harbor union leader Kunihiro Kajiwara at close range in broad daylight after he resisted pressure to favor the gang in lucrative public works contracts.

Prosecutors later linked the group to grenade attacks on the homes of Kyushu Electric Power executives and even to firebomb attacks on property tied to future prime minister Shinzo Abe, in an effort to pressure officials over public-works decisions and development projects.

Japan’s courts responded unusually harshly: Kudo-kai boss Satoru Nomura was sentenced to deathan almost unheard-of penalty for an organized-crime leadersignaling that the state views attacks on civilians and public officials as a red line that even the yakuza cannot cross.

2. The Assassination of Nagasaki Mayor Iccho Itoh

On April 17, 2007, Nagasaki mayor Iccho Itoh was shot twice in the back outside a train station just days before an election. The killer, Tetsuya Shiroo, was a senior figure in a local group affiliated with the Yamaguchi-gumi, Japan’s largest yakuza syndicate.

Officially, Shiroo was angry that the city refused to fully compensate him after his car was damaged at a public-works site. But investigative reporting pointed to a bigger issue: Itoh’s administration had been refusing to award construction contracts to yakuza-linked companies, cutting off a vital revenue stream. The assassination shocked a country where political assassinations had become extremely rare and helped galvanize stricter local “exclusion ordinances” aimed at freezing gangs out of legitimate business.

3. Sex Trafficking and the Case of Marcela Loaiza

Not all brutal yakuza crimes involve bullets. In the late 1990s, Colombian woman Marcela Loaiza accepted an offer to work as a dancer in Japan. When she arrived, her passport was seized, she was told she owed tens of thousands of dollars, and she was forced into prostitution in Tokyo under the control of yakuza traffickers.

Loaiza later described being worked to collapse, threatened, and treated “like an object.” After roughly two years she managed to escape with the help of the Colombian embassy, eventually writing a memoir and founding an anti-trafficking organization. Her story is far from unique: U.S. State Department reports have repeatedly described Japan as a “destination, source and transit country” for sex trafficking, with organized crime groups deeply involved in recruiting, transporting, and exploiting foreign women.

4. Insider Trading and Financial Infiltration

As Japan’s economy modernized, yakuza groups didn’t just shake down neighborhood bars; they moved into the boardroom. In the 2000s, investigative reporting revealed that gangsters were using threats to obtain insider information, then trading stocks for big profits while also engaging in illegal “sokaiya” shareholder blackmail schemes.

In 2011, Japanese banksmost notably Mizuho Financial Groupadmitted they had made hundreds of loans that indirectly benefited yakuza borrowers, triggering national scandal and regulatory scrutiny.

The U.S. Treasury has since sanctioned major yakuza groups and front companies, cutting them off from dollar-based transactions and underscoring that Japanese organized crime has long been transnational and financially savvy, not just tattooed bruisers in smoky back rooms.

5. Dogfighting Rings and the Business of Cruelty

Dogfights involving the powerful Tosa breed have existed in Japan for centuries, but in modern times the business has deep ties to organized crime. Investigations and academic work on illegal dogfighting note that yakuza members often breed, buy, and sell fighting dogs, collecting substantial profits from both the animals and the underground betting that surrounds the matches.

A purebred Tosa can sell for thousands of dollars, and a winning dog can fetch even more. Gambling on the fights may technically be laundered through prize systems similar to pachinko, but the effect is the same: cash flows into gang coffers, while the animals bear the cost. Animal-welfare groups have reported intimidation when they push too hard to ban the practice, which illustrates how yakuza violence can be used to resist reform even in seemingly “niche” criminal markets.

6. The 1.86 Billion Yen ATM Heist

In May 2016, an extremely coordinated, high-tech crime hit ATMs across Japan. In the span of about two hours, criminals used fake cards cloned from data stolen at South Africa’s Standard Bank to make withdrawals at around 1,400 machines, netting roughly 1.8 billion yen (about $16–17 million).

Japanese media and police later linked upper-level Yamaguchi-gumi members to parts of the operation, treating it as a textbook example of how modern yakuza blend traditional hierarchy with global cybercrime and data breaches. The case also pushed Japanese banks to harden ATM security and cooperate more closely with overseas financial institutions.

7. Sumo Betting, Blackmail, and Match Fixing

If you want to understand how deeply yakuza influence can seep into mainstream culture, look at professional sumo. In 2010, a major scandal erupted when top-ranked wrestler Kotomitsuki admitted to betting illegally on baseball games through yakuza bookmakersand to being blackmailed by gang members who threatened to expose his gambling.

Further investigations uncovered evidence of wider match fixing and revealed prized ringside seats ending up in the hands of Yamaguchi-gumi bosses who wanted to show off their status on national television. Public outcry was so intense that NHK briefly halted live sumo broadcasts, sponsors fled, and the sport’s governing body vowed to ban “violent groups” from arenas and training stables.

8. The Kobe Yamaguchi-gumi Split and Factional Shootings

In 2015, a major schism rocked the Yamaguchi-gumi. A large Kobe-based faction broke away to form the Kobe Yamaguchi-gumi, reviving memories of the bloody Yama-Ichi war of the 1980s. Police quickly labeled both sides “designated dangerous organizations,” fearing a repeat of earlier gang wars that had left dozens dead.

Between late 2015 and early 2016, shootings, beatings, and property attacks linked to the split were recorded in prefectures across Japan. A senior Kobe Yamaguchi-gumi member was shot dead in May 2016, and the black-market price of handguns surged. Police responded with mass arrests and highly visible raids on gang offices to contain the violence.

9. Tadamasa Goto and the Murder of a Real-Estate Broker

Tadamasa Goto, sometimes dubbed “the John Gotti of Japan,” built the Goto-gumi into a particularly feared Yamaguchi-gumi affiliate known for targeting civilians, not just rival gangsters. One notorious case involved the 2006 stabbing death of real-estate broker Kazuoki Nozaki, who was helping evict occupants from a property that had passed through yakuza-linked hands.

Nozaki’s family later sued Goto personally for employer liability. While he did not admit guilt, Goto agreed to pay around 110 million yen and issued an apologyan unusually public civil resolution that highlighted how yakuza violence can intersect with seemingly mundane disputes over land and tenants.

10. The Attack and Suspicious Death of Filmmaker Juzo Itami

In 1992, director Juzo Itami released Minbo: The Gentle Art of Japanese Extortion, a dark comedy ridiculing yakuza shakedown tactics. Six days later, gang members ambushed him outside his home and slashed his face, a warning that he later said confirmed he had hit a nerve.

In 1997, Itami died after falling from a building in what was officially ruled a suicide. But journalists and former detectives have long suspected that yakuza threatened him and forced him to jump, possibly because he was reportedly researching links between a major religious organization and the Goto-gumi. The case remains controversial, a chilling reminder of how organized crime can push back against scrutiny.

11. The Yama-Ichi War: A Mafia Civil War in Peaceful Japan

In 1985, a succession dispute inside the Yamaguchi-gumi spiraled into a full-scale gang war when dissidents formed the Ichiwa-kai and assassinated boss Masahisa Takenaka. Over the next two years, tit-for-tat shootings and bombings killed around 25 people and injured about 70 more, including at least one police officer.

Newspapers ran literal scorecards tracking casualties, a surreal sight in a society that otherwise enjoys very low levels of violent crime. The conflict finally ended in 1989 when the main Yamaguchi-gumi faction prevailed and remaining Ichiwa-kai members were allowed back into the fold. The war helped convince policymakers that “business as usual” with the yakuza was no longer acceptable, paving the way for tougher anti-gang laws in the 1990s.

12. The Glico-Morinaga Extortion Case and the “Monster with 21 Faces”

Between 1984 and 1985, an anonymous group calling itself the “Monster with 21 Faces” kidnapped Ezaki Glico president Katsuhisa Ezaki, threatened to lace candies with cyanide, and extorted multiple food companies, forcing massive product recalls and causing huge financial losses. Despite enormous public fear, no one was killed, and the perpetrators were never caught.

Police examined many possibilities, including disgruntled employees, left-wing extremists, and yakuza involvement. One key suspect had a father who led a local yakuza group, and some investigators speculated that gang members helped carry out parts of the plot. However, the case remains officially unsolved, and any yakuza role has never been provenunderscoring how murky the boundary can be between organized crime, political violence, and personal vendetta.

13. Potential Tokyo 2020 Olympics Corruption

Mega-events attract mega-opportunities for corruption. A 2014 investigative piece raised alarms about possible yakuza influence around Tokyo’s bid for the 2020 Olympics, noting the close friendship between Hidetoshi Tanakathen a vice-chair of Japan’s Olympic committee and influential sumo insiderand Hareaki Fukuda, a top leader of the Sumiyoshi-kai, Japan’s second-largest yakuza syndicate and the target of U.S. sanctions.

While no criminal charges directly tied the Games to yakuza bosses, the overlap between construction contracts, real-estate development, sports organizations, and known gang connections shows how organized crime can lurk in the shadows of even the most polished international events.

14. “Pineapples” in Fukuoka: Hand Grenades on the Streets

In yakuza slang, a “pineapple” isn’t a pizza toppingit’s a hand grenade. During the 2000s and early 2010s, turf wars in Fukuoka Prefecture featured enough grenade attacks that local police offered cash rewards for information about anyone possessing them, a first in Japan.

In one especially grim incident in 2011, a grenade exploded in a car at night, killing two people and injuring more than a dozen. In another, a child found a grenade in a field and brought it home, forcing authorities into emergency response mode. The fact that gang disputes spilled over into random public danger helped shift public opinion firmly against tolerating yakuza “as long as they keep to themselves.”

15. The Seven-Year War Between Seido-kai and Dojin-kai

In 2006, a leadership dispute inside the Dojin-kai in Kyushu led to the creation of a breakaway group, the Kyushu Seido-kai, which aligned itself with the Yamaguchi-gumi. What followed was a years-long feud marked by AK-47 attacks, car bombs, and shootings that sometimes hit innocent bystanders, including a patient in a hospital who was killed when a gunman targeted the wrong man.

The conflict dragged on until around 2013, leaving multiple gangsters and civilians dead and turning parts of Fukuoka into what locals called a low-level war zone. Finally, the Seido-kai announced its dissolution and issued a written apology acknowledging that its existence had disturbed the public and “been a nuisance to society.”

16. The Murder of Ryoichi Sugiura

In 2007, senior Sumiyoshi-kai figure Ryoichi Sugiura was shot in the head and chest while sitting in his car in central Tokyo. The brazen killing, carried out by gunmen from a Yamaguchi-gumi affiliate, came amid tensions between the two largest yakuza syndicates and was believed to be tied to disputes over lucrative land deals.

Police feared an all-out war. There were immediate retaliation shootings at Yamaguchi-gumi offices, and some streets were temporarily locked down. But authorities and senior bosses had enough incentive to avoid a full repeat of the 1980s, and the violence eventually simmered down.

17. The Assassination of Masaru Takumi

Masaru Takumi, the powerful second-in-command of the Yamaguchi-gumi, was widely seen as a likely future godfather. In 1997, he was gunned down in a coffee shop at Kobe’s Oriental Hotel by members of the breakaway Nakano-kai. A nearby dentist was hit by a stray bullet and died days latercollateral damage in a feud that had little to do with him.

One of the hitmen remained at large for years before being arrested and sentenced to life in prison in 2014. The killing highlighted how succession disputes inside a syndicate can erupt into very public violence, destabilizing both the underworld and nearby communities.

18. The Murder of Two Plainclothes Police Officers

In 1990, Kyokuryu-kai member Hideo Zamami mistook two plainclothes police officersMasao Higa and Shokichi Hainefor rival gangsters. He opened fire on their car, killing both officers and wounding a passing woman who happened to be driving by.

Zamami received a life sentence, but another senior gang figure believed to be involved in the killings was never prosecuted before the statute of limitations expired. The case infuriated the public and law-enforcement community, reinforcing the idea that yakuza violence can spill onto anyone, including those tasked with fighting it.

19. The Killing of Tatsuyuki Hishida

In November 2015, second-tier Yamaguchi-gumi boss Tatsuyuki Hishida was found dead in his home, hands and feet bound, head beaten with a blunt object. Investigators suspected the attack was connected to the then-fresh split between the Yamaguchi-gumi and the Kobe Yamaguchi-gumi factions.

The murder underscored how factional disputes inside a declining syndicate can actually increase short-term violence, even as overall membership falls. Turf, pride, and the flow of money still matterand some members are ready to resort to extreme brutality to protect them.

What Modern Yakuza Crimes Tell Us About Japan Today

Taken together, these crimes paint a picture of an underworld that is both changing and dangerous. Classic hits and gang wars still happen, but so do cyber-heists, stock-market schemes, trafficking networks, and attempts to cozy up to big events like the Olympics.

At the same time, the yakuza are weaker than they’ve been in decades. Membership has plummeted from around 80,000–90,000 in the mid-2000s to roughly the low-20,000s or even under 20,000 in recent years, as anti-gang ordinances make it harder for members to rent apartments, open bank accounts, or do business under their own names.

Those crackdowns have side effects: as traditional syndicates are squeezed, more fluid online crime networks (“tokuryu”) and freelance criminals are stepping into the gap, sometimes collaborating with remaining yakuza but not bound by the same hierarchies or informal “rules.”

Experiences and Reflections on These Crimes (Approx. )

It’s easy, especially from afar, to file the yakuza away as stylish movie villains: sharp suits, full-body tattoos, smoky back rooms, and gravelly speeches about honor. The real experiences of people caught up in their crimes tell a very different storyone that feels less cinematic and more claustrophobic.

Consider the Glico-Morinaga case from the perspective of an ordinary family in 1980s Japan. You’re sending your kids to school, packing snacks in their backpacks, and suddenly every evening newscast is talking about cyanide-laced candies. Supermarkets pull products off shelves. Police patrol outside food factories. The anonymous “Monster with 21 Faces” taunts authorities in letters printed in national newspapers. Even if you never see a gangster in your life, you’re living in a climate of fear someone else created for leverage and profit.

Or think about the sex-trade cases. For someone like Marcela Loaiza, the yakuza weren’t abstract “mafiosi,” they were the men who took her passport, controlled her movements, and decided how many clients she had to see just to keep chipping away at a fictional debt. Her description of trafficking as “a tattoo on the soul” captures how the trauma doesn’t end when the physical captivity does. Survivors carry the psychological weight into every new relationship and workplace, often in countries that barely acknowledge what happened to them.

Communities in places like Fukuoka and parts of Kyushu have a different kind of experience. When hand grenades become a recurring feature of local newspeople finding them in fields, blasts going off in parking lotsthe idea that “Japan is safe” starts to feel conditional. Residents learn which streets to avoid at night, which buildings belong to which groups, which bars are rumored to be gang hangouts. Parents quietly warn their kids without wanting to scare them. Small business owners may have to choose between reporting extortion attempts and risking retaliation, or paying quietly and hoping police pressure will eventually bring relief.

Even in the sumo scandals, the experience is one of betrayal more than spectacle. Fans tuning in to watch a beloved national sport discovered that some wrestlers were gambling through yakuza intermediaries or fixing matches. That realization erodes trust far beyond the individuals involved; it raises uncomfortable questions about who else behind the scenes is compromisedcoaches, promoters, even federation officials.

Perhaps the most unsettling layer is how ordinary many settings are: a hospital where a civilian is mistakenly shot, a coffee shop where a boss is assassinated, an ATM where someone quietly drains foreign bank accounts, a city office that becomes the target of an angry gunman. These aren’t hidden lairsthey’re the same spaces everyone else uses.

For law-abiding residents, living alongside the yakuza has historically meant a mix of wary coexistence and quiet fear. As police repression and social norms make gang life less attractive, that coexistence is changing. Younger would-be criminals may now gravitate more toward anonymous online fraud than tattoo-and-pinky-finger hierarchies. But the lesson from these 19 cases is consistent: as long as there is money to be made and power to be grabbed, there will be groups willing to use extreme violence, intimidation, and exploitation to get it. The challenge for Japanand every other countryis how to reduce the harm they do without creating new, even harder-to-see threats in the process.

Conclusion

Modern yakuza crimes run the gamut from gruesome assassinations to quiet financial schemes, from grenade attacks on busy streets to psychological terror via poisoned-candy threats. They show how a once semi-“visible” underworld has adapted to a world of tighter regulation and digital finance, even as its power slowly declines.

For policymakers and citizens alike, the takeaway is blunt: you can’t romanticize organized crime just because it comes wrapped in tradition or tattoos. The real measure is the damage done to victims, communities, and institutionsand by that standard, these 19 cases are a stark reminder that even in one of the world’s safest countries, organized crime can be both brazen and brutally effective.
