Japan is facing a shortage of Asahi products, including beer and bottled tea, as the drinks giant grapples with the impact of a major cyber-attack that has impacted its operations in the country.
Most of the Asahi Group's factories in Japan have been at a standstill since Monday, after the attack hit its ordering and delivering systems, the firm has said.
Major Japanese retailers, including 7-Eleven and FamilyMart, have now warned customers to expect shortages of Asahi products.
Asahi has temporarily suspended orders and shipments of its products, with no prospect of resumption, FamilyMart stated.
The firm - which is one of Japan's largest convenience stores - said its Famimaru range of bottled teas is expected to be in short supply or out of stock.
We sincerely apologise to our customers for any inconvenience caused, FamilyMart added, explaining they are working with Asahi to resume the sale of the products.
7-Eleven, the Japanese-owned global convenience store chain, has halted shipments in the country of Asahi products, including its popular Super Dry beer.
A spokesperson for 7-Eleven said its shops have been advised to expect a shortage of Asahi products.
Lawson, another major Japanese retailer, also said they expected some Asahi products to be in short supply from today.
The retailer plans to stock up on alternative products to minimize disruption.
Japanese supermarket chain, Life Cooperation, is also concerned that Asahi products may soon go out of stock.
Asahi is the biggest brewer in Japan and owns global brands like Peroni, Pilsner Urquell, and Grolsch.
Japan accounts for about half of its total sales.
Besides beer, Asahi produces soft drinks and food products, also supplying own-brand goods to retailers like FamilyMart.
Asahi said earlier this week that the system failure is limited to its operations in Japan, with its European business unaffected. There has been no confirmed leakage of customer data.
We are actively investigating the cause and working to restore operations; however, there is currently no estimated timeline for recovery, the company reported.
