Our People

We have more than 37,000 multi-national employees operating farms, manufacturing facilities and offices in across Asia.

As we grew in scale, products and geographical locations; our industry know-how has also expanded from animal feed to livestock breeding, commercial farming, dairy and consumer food production.

Our corporate culture is a key contributing factor to our success in building agri-food infrastructure in some of the most challenging emerging markets.

For more than five decades, we have abided by a set of founding values based on integrity, mutual benefit, and cohesiveness in achieving common goals. These values that are handed down from one generation of Japfa employees to another have shaped our approach to product quality, business and community relations.
