As cities evolve, they often begin to resemble one another, shaped by familiar patterns of development. Yet some places retain a character of their own—and continue to be chosen, generation after generation. Ochanomizu is one of them. View of the Kanda River and railway tracks from Hijiri Bridge The area around JR Ochanomizu Station is defined by its complex terrain. With landmarks like Hijiri Bridge and the steep slopes running along the Kanda River, the neighborhood offers a vivid sense of Tokyo’s layered geography. Simply walking through it, you begin to understand just how intricate the city really is. And then, along those slopes overlooking the river valley, an unexpected scene unfolds. Shops with walls covered entirely in guitars. Showcases filled with vintage brass instruments. Out front, young musicians pick up instruments and play—faces serious, completely absorbed in the moment. Even today, Ochanomizu remains one of the largest and most concentrated musical instrume...
Currently, Japan is abuzz with news about a company hit by an unexpected crisis.
It is a cyberattack targeting Asahi Breweries, one of Japan’s leading beer companies — an incident whose impact extends far beyond a single business.
Asahi is the brewer behind Asahi Super Dry, Japan’s most famous beer.
Its sleek silver cans have long been a familiar sight on convenience store shelves across the country.
But after the company suffered a major system failure, distribution was disrupted, and some regions began to report temporary shortages of Super Dry.
It was almost unthinkable: a cyberattack threatening the supply of what many see as Japan’s national drink.
Asahi Group — Japan’s Largest Beer Empire
Asahi Group Holdings (Asahi GHD) is one of Japan’s largest beverage manufacturers.
Its flagship product, Asahi Super Dry, launched in 1987, revolutionized Japan’s beer culture with its karakuchi (dry, crisp flavor) and quickly propelled the company to the top of the market.
Here, “dry” doesn’t mean bitter—it refers to a clean, refreshing finish that reshaped the nation’s taste for beer.
But Asahi’s reach extends far beyond beer. The company owns breweries, distilleries, and wineries around the world, producing wine, whisky, coffee, soft drinks, and even health foods and pet products.
In short, Asahi is more than a beer company—it’s a pillar of Japan’s food and beverage culture.
In Tokyo’s Asakusa district, the company’s headquarters on the banks of the Sumida River is famous for its golden, flame-shaped sculpture—a symbolic “foam of beer” that dominates the skyline.
As of 2024, Japan’s beer market is roughly divided as follows:
| Brewer | Main Brands | Estimated Market Share |
|---|---|---|
| Asahi | Super Dry | ~35% |
| Kirin | Ichiban Shibori, Lager | ~30% |
| Suntory | The Premium Malt’s | ~20% |
| Sapporo | Black Label, Yebisu | ~10% |
The Attack — Qilin and the “Double Extortion” Threat
On the morning of September 29, Asahi’s internal systems suddenly shut down.
The cause: a ransomware attack, a type of malicious software that encrypts company data and demands payment for its release.
The group claiming responsibility called itself Qilin, believed to be a Russian-speaking hacker collective.
Qilin, previously known as Agenda, is notorious for “double extortion” tactics—locking company data while simultaneously threatening to leak stolen information online.
Reports suggest that around 27 GB of Asahi’s internal data may have been compromised, potentially including employee and contract records.
Ironically, in Japan, the group’s name Qilin is pronounced the same as Kirin, Asahi’s longtime rival beer company.
This coincidence even sparked humorous speculation that Asahi was targeted for the wordplay.
In reality, the hackers’ name is thought to come from the Chinese mythical creature Qilin (Kirin in Japanese)—a symbol of good fortune and prosperity, which happens to be the same origin as Kirin Brewery’s name.
When the Taps Went Dry — Business Impact
The full scale of the damage remains unclear, but recovery is expected to take time.
Asahi’s stock price dipped temporarily, and on October 14, the company announced it would postpone its financial report for the January–September 2025 period (originally scheduled for November), citing difficulties in verifying accounting data.
The disruption has spread beyond beer: new beverage launches, including several Calpis Soda and Mitsuya Cider products, have been delayed.
With digital systems down, wholesalers were unable to place orders, forcing some factories to revert to pen, paper, and fax machines—a jarring throwback in Japan’s high-tech society.
The impact rippled across the entire industry.
Restaurants and retailers facing shortages turned to other brands—Kirin, Suntory, and Sapporo—prompting a sudden surge in demand that required even those companies to adjust shipments.
It was as if one cog in a vast machine had stopped, causing the entire system to shudder.
A Cultural Shock Beyond Logistics
Even as summer fades, beer remains central to Japanese social life.
As the year-end approaches, beer sets are popular oseibo (gift-giving) items, and the bonenkai season—the traditional “forget-the-year” parties—fills restaurants with lively toasts.
Coworkers and friends clink beer mugs and say “Otsukaresama!” (“Good job this year!”)—a ritual as ingrained as the celebration itself.
That’s why this disruption struck deeper than logistics.
It wasn’t just about running out of beer—it was about interrupting a cultural rhythm, a shared moment of cheer that defines the Japanese year’s end.
A Warning for a Digital Japan
The Asahi incident exposed how tightly Japan’s everyday culture is now bound to digital infrastructure.
A single piece of ransomware was enough to remind the country that even something as simple as a toast of beer depends on invisible networks of data, logistics, and trust.
While recovery continues, one hope unites office workers and bar regulars alike:
that soon, they’ll once again raise a glass of Super Dry and say, with a smile—
“Kanpai!”
