Japanese sales sections are usually called Eigyo-bu (Eigyo department). Eigyo literally means sales. But, Eigyo does not mean sales only, rather Eigyo refers to conducting business. Because of this, Eigyo personnel play a bigger role than regularly titled sales personnel. We will introduce the concept of Eigyo and what roles and implications of a typical Eigyo department plays within a firm. Eigyo departments sometimes incorporate functions implemented by the other departments within their company. We will conclude that marketing functions can be integrated not only by a marketing manager but also by people in other positions, such as sales managers. Managerially speaking, this may deem more efficient and effective in turbulent, unpredictable marketplaces.
