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 affected 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.
Major Japanese retailers, including 7-Eleven and FamilyMart, have now warned customers to expect shortages of Asahi products.
In a statement on Friday, Asahi said it was "unable to provide a clear timeline for recovery" but had started "partial manual" processing of orders and shipments.
Asahi is the biggest brewer in Japan, but it also makes soft drinks and food products, as well as supplying own-brand goods to other retailers.
