Japan's top five brewers saw shipments of beer fall 12.9% in January this year, compared to the same month last year. It is the first fall in two months.

Kirin Brewery, Asahi Breweries, Sapporo Breweries, Orion Breweries and Suntory Ltd shipped a combined 21.53m cases of beer, happoshu (a low malt alternative to beer) and beer-like beverages in the month.

One case holds 12.66 litres, or the equivalent of 20 633-millilitre bottles.
