Good news for beer lovers.
The legal definition of beer changes on Sunday, and Japan's major breweries are looking to shore up their shrinking customer bases by introducing new products with a wider variety of flavors to shake up the stagnant market.
Under the old definition, beers need to be made from water and hops and have a malt content of 67 percent or higher. But that will be lowered to 50 percent from April, marking the first change in 110 years.
