Asahi Super Dry is Japan’s most popular beer<\/figcaption><\/p>\n<\/figure>\n
\n

Only four bottles of Asahi Super Dry beer are left on the shelves of Ben Thai, a cosy restaurant in the Tokyo suburb of Sengawacho.<\/p>\n

Its owner, Sakaolath Sugizaki, expects to get a few more soon, but she says her supplier is keeping the bulk of its stock for bigger customers.<\/p>\n

That’s because Asahi, the maker of Japan’s best-selling beer, was forced to halt production at most of its 30 factories in the country at the end of last month after being hit by a cyber-attack.<\/p>\n

While all of its facilities in Japan – including six breweries – have now partially reopened, its computer systems are still down.<\/p>\n

That means it has to process orders and shipments manually – using pen, paper and fax machines – resulting in much fewer shipments than before the attack.<\/p>\n<\/div>\n

\n

Asahi accounts for about 40% of Japan’s beer market, so its problems are having a major impact on bars, restaurants and retailers.<\/p>\n

The company has apologised “for any difficulties caused by the recent attack” but has not yet said when it expects its operations to be fully up and running again.<\/p>\n

The BBC visited convenience stores and supermarkets in Tokyo and Hokkaido – where workers said they were selling their current stock and hadn’t been able to place new orders for Asahi products, which also include water and food items.<\/p>\n

Hisako Arisawa, who runs a liquor store in Tokyo, says she is worried about her customers as she can only get a few bottles of Super Dry at a time and expects the disruption to go on for at least a month.<\/p>\n

The problem isn’t just affecting beer, she adds, there are also shortages of Asahi’s soft drinks, such as ginger beer and soda water.<\/p>\n<\/div>\n

Convenience stores in Japan have warned of shortages of Asahi products<\/figcaption><\/p>\n<\/figure>\n
\n

Last week, some of the country’s biggest convenience store chains warned their customers to expect shortages<\/a>.<\/p>\n

FamilyMart said its Famimaru range of bottled teas, which are made by Asahi, were expected to be in short supply or out of stock.<\/p>\n

7-Eleven halted shipments in Japan of Asahi products, while Lawsons also said it expected shortages.<\/p>\n

Mr Nakano, who didn’t want to share his first name, works for an alcohol wholesaler.<\/p>\n

While some shipments from Asahi have resumed, he says he is only getting about 10-20% of the normal amount.<\/p>\n

His orders are now handwritten and taken by fax. Asahi notifies him by fax when lorries are ready to leave its factory.<\/p>\n

Asahi also owns big brands in Europe – such as Peroni, Grolsch, and the British brewer Fuller’s – but the firm has said those operations have not been affected by the cyber-attack.<\/p>\n<\/div>\n

\n

Ransomware group Qilin – which has previously hacked other major organisations – has claimed responsibility for the attack on Asahi.<\/p>\n

It operates a platform that allows users to carry out cyber-attacks in exchange for a percentage of extortion proceeds.<\/p>\n

Asahi has not confirmed the nature of the attack on its operations but has said data suspected to have been leaked in the hack had been found on the internet.<\/p>\n

It is the latest in a series of cyber-attacks by other hacking groups that have hit major firms around the world, including carmaker Jaguar Land Rover and retail giant Marks and Spencer<\/a>.<\/p>\n

Travellers were delayed at a number of European airports in September after a ransomware attack disrupted check-in and boarding software.<\/p>\n

Back in Japan, a cyber-attack paralysed operations at a container terminal in the city of Nagoya for three days in 2024.<\/p>\n

Japan Airlines was also hacked last Christmas, causing delays and cancellations to domestic flights.<\/p>\n<\/div>\n

While Japan’s image around the world may be of a technologically advanced nation, some experts have warned it does not have enough cybersecurity professionals and has low rates of digital literacy when it comes to business software.<\/p>\n

This issue was highlighted last year when officials finally stopped asking people to submit documents to the government using floppy disks<\/a>, even though they fell out of fashion in much of the rest of the world in the 1990s.<\/p>\n

Japan is vulnerable to cyber-attacks “given a reliance on legacy systems and a society with a high level of trust,” Cartan McLaughlin from Nihon Cyber Defence Group told the BBC.<\/p>\n

Many organisations in the country are not prepared for attacks and are willing to pay ransoms, which makes them attractive to hackers, he added.<\/p>\n

Speaking at a news conference this week, Japan’s Chief Cabinet Secretary Yoshimasa Hayashi said the Asahi cyber-attack was being investigated.<\/p>\n

“We will continue to improve our cyber capabilities,” he added.<\/p>\n

Earlier this year, the Japanese government passed a landmark law giving it more powers in the event of cyber-attacks.<\/p>\n

Experts have praised the Active Cyber Defense Law (ACD), because it allows the government to share more information with companies, and also empowers the police and Japan’s Self-Defense Forces to mount their own attacks to neutralise attackers’ servers.<\/p>\n

But that is little consolation to small businesses like Ben Thai restaurant and its customers.<\/p>\n

Owner Sakaolath says she’s not sure what will happen the next time she puts in an order for Super Dry, and nor do many others across Japan.<\/p>\n<\/div>\n
