Company information
Ebis Trade Co., Ltd.'s "Ebis" is derived from three words: "e-business," "good business," and "Ebisu." These three words continue to form the foundation of our management vision. "E-business" represents the history of Ebis Trade. It was established in March 2000 with the aim of launching a business in the IT field, which holds infinite possibilities, under the banner of a "comprehensive internet trading company." Since then, we have expanded our business scope from IT to new growth segments such as environment, safety, automotive, and Russia (Siberia and the Far East). The second term, "good business," reflects Ebis Trade's business philosophy. Good business not only brings joy to those who are engaged in it but also to those around them, thereby energizing society and brightening the world. When work is enjoyable, life becomes richer. Finally, "Ebisu" represents Ebis Trade's core competence. "Ebisu" is derived from "Ebisu-sama," the god of commerce. Like Ebisu-sama, who is the deity of trade, we aim to be a "group of professionals in commerce." Ebis Trade's dream is to create a society where "everyone doing good work has an Ebisu smile," overflowing with such smiles.
