E iichi Kuriwada is a Japanese billionaire who is the chairman of Sagawa Express, a major Japanese logistics and delivery company. His fortune is derived from his family's controlling stake in the company's parent, SG Holdings. The company is a key player in Japan's highly efficient and competitive parcel delivery market, second only to the giant Yamato Holdings (Kuroneko).

The Kuriwada family gained control of the company from its scandal-plagued founder. Eiichi Kuriwada has been the leader who has professionalized the company and guided it for many years. Under his leadership, SG Holdings held a highly successful initial public offering on the Tokyo Stock Exchange in 2017, one of the largest in Japan that year, which brought the family's immense wealth into the public spotlight.
