When you think of Japan, you probably picture sushi, Mount Fuji, neon-lit streets, or polite culture. But there’s another layer hidden, powerful, and dangerous that rarely shows up in travel brochures: the dark side of Yakuza in the Japanese government.
Yes, the Yakuza. Japan’s notorious mafia groups aren’t just tattoo-covered gangsters in movies. They’re real. And what’s more troubling is that some of them have been creeping dangerously close to the country’s political and governmental systems for decades.
Let’s break down what’s really going on behind closed doors, and why we should care.

So, Who Are the Yakuza Really?
The Yakuza are Japan’s organized crime syndicates one of the oldest in the world. Unlike most criminal gangs that operate underground, the Yakuza have, for decades, maintained a public presence. They have offices, business cards, and even websites (seriously). Some even pay taxes.
But don’t let their oddly official appearance fool you. Behind their business suits and flashy rings lies a world of extortion, gambling, human trafficking, loan sharking, fraud, and racketeering.
What’s worse? These groups, particularly giants like the Yamaguchi-gumi, Sumiyoshi-kai, and Inagawa-kai, have historically had connections not just with local businesses but also with political figures and governmental institutions.
Yakuza and the Japanese Government: A Long, Dark History
Here’s where things get uncomfortable.
Historically, some politicians have used Yakuza muscle to suppress protests, sway public opinion, or secure votes. In return, Yakuza receive legal protection, insider information, and even profitable government contracts through shell companies.
This shady handshake dates back decades. For example, during Japan’s post-WWII reconstruction, some right-wing politicians allegedly leaned on the Yakuza for support in stabilizing chaotic regions. The line between “protector” and “criminal” got blurry fast.
Even as recently as the 2000s, stories emerged of politicians attending Yakuza-hosted events, or appearing in photographs alongside known gang leaders. Although not every case led to prosecution, the stench of corruption was undeniable.

How Do They Influence the Government?
Here’s how the dark side of Yakuza in the Japanese government really operates:

1. Funding Political Campaigns
Yakuza organizations have deep pockets. Some reports suggest that they funnel money into political campaigns through third-party donors or businesses. Politicians in debt to these “donors” may later return favors through lenient policies or access to public contracts.
2. Controlling Public Contracts
Ever heard of bid-rigging? In Japan, it’s called dango. Yakuza groups have been known to manipulate public construction bids. By intimidating competitors or colluding with insiders, they help their own companies win lucrative government projects bridges, tunnels, even Olympic infrastructure.
3. Blackmail and Influence
Yakuza are masters of jiji, or blackmail. If a bureaucrat, official, or politician has a scandalous past, Yakuza groups may use that info to manipulate decisions or secure immunity. It’s not just physical threats they play mind games, too.
Why Doesn’t the Government Just Shut Them Down?
Good question. Japan has actually made several efforts to crack down on Yakuza activity. Laws like the Anti-Boryokudan Act (1992) and regional anti-gang ordinances have made it illegal to knowingly do business with Yakuza-affiliated groups.
Still, enforcement is a challenge. Here’s why:
- Yakuza groups are adaptive – As laws tighten, they switch from physical extortion to white-collar crime. Think crypto fraud, stock manipulation, or fake real estate deals.
- Their businesses look legal – They use front companies that appear squeaky clean. Banks, nightclubs, restaurants, even tech startups. Unless you dig deep, they’re hard to trace.
- Some politicians still fear them – Either because they owe them favors, or because Yakuza know too much. Silence becomes safer than action.

Real Scandals That Reveal the Truth
Let’s not talk in hypotheticals. Here are real-life cases that shed light on how Yakuza and the government have crossed paths:
🕵️♂️ Olympics Security Scandal (Tokyo 2020)
A firm contracted for Olympic event security was reportedly linked to a company with Yakuza ties. Although the government denied wrongdoing, journalists raised red flags about conflict of interest and background checks.
📷 The Ishihara Photo Leak
In 2011, Shintaro Ishihara, Tokyo’s then-governor, was pictured with a known Yakuza member. Though he claimed ignorance, the photo stirred debates about how close public officials were to crime groups.
💰 Political Slush Funds
Several lawmakers have faced investigation over “missing” campaign funds some of which allegedly flowed through shady intermediaries with Yakuza connections.
Are Things Getting Better?
Yes… and no.
The Yakuza’s public presence is shrinking. From over 90,000 members in the early 1990s, numbers dropped to about 24,000 by 2023. That’s partly thanks to tougher laws and social rejection many banks, landlords, and businesses now refuse to work with gang members.
But here’s the twist: as they shrink physically, they grow strategically.
They’re moving into cybercrime. They’re investing in foreign markets. And most alarmingly, they’re polishing their image wearing suits, speaking English, and operating as “businessmen” in places like Hong Kong, Thailand, and even New York.
This “new Yakuza” may not swing katanas in alleys, but they’re just as dangerous because now, they wear masks of respectability.

What Can Be Done?
Here’s what experts suggest to finally sever the Yakuza’s influence on government:
- Transparency in political funding
Public databases of all campaign donors should be made mandatory and actively monitored. - Stronger financial oversight
Authorities need to audit suspicious contracts and corporate structures more aggressively. - Whistleblower protections
Journalists and insiders must be shielded if they expose Yakuza government links. - Public education
The Japanese public and the world needs to be more aware of how criminal groups evolve. Crime doesn’t always look like crime.
Final Thoughts
Yakuza stories may feel like scenes from a Netflix drama, but they’re very real. And the dark side of Yakuza in the Japanese government is a reminder that power and crime often share a handshake in the shadows.
As Japan continues to modernize and globalize, rooting out these hidden connections is not just a legal matter it’s a moral one. The country’s reputation, democracy, and public safety depend on it.
So next time you admire Japan’s clean streets and futuristic trains, just remember: the battle between law and organized crime may still be quietly unfolding behind those glass walls.
