With traditional family farms on the wane, corporations are increasingly entering the agriculture sector, taking advantage of an updated law allowing them to lease farmland across the country.

At the end of 2015, more than 2,000 companies were operating in the farm sector, a roughly five-fold increase from before the farmland law was revised in 2009, according to the Agriculture, Forestry and Fisheries Ministry.

Among them is Morishige Bussan Co., a food wholesaler in the city of Saitama that's growing perilla on a 6-hectare patch of hilly land in Chichibu, Saitama Prefecture.
