Japan's major beer makers are increasingly focusing on growing overseas markets as domestic demand is expected to dwindle.
They have been forming strategic partnerships with international rivals and acquiring breweries with sales networks in Asia and Africa.
Sapporo Breweries has agreed with Danish beer maker Carlsberg Group to form a joint venture in December.
It is aiming to boost sales in six countries and regions in Asia including Vietnam and Singapore.
The Japanese beer maker said earlier this month it will invest 643 million dollars in the joint venture for access to Carlsberg's sales networks.
Sapporo Breweries President Tokimatsu Hiroshi said: "It would take quite a long time to build a solid sales network in overseas markets on our own. We believe the tie-up is a strategic solution to this issue and will achieve growth more efficiently and speedily."
Sapporo's domestic rival, Asahi Group Holdings, said last year it would acquire the beer and liquor business of British beverage giant, Diageo, in Kenya, Tanzania and Uganda.
The combined population of the three East African countries exceeds that of Japan at more than 170 million, and their beer markets have seen rapid growth.
