Nippon Express Company, Ltd., was established in 1937 in line with the Nippon Tsu-un Kaisha Law as a semi-government transportation enterprise. The Company was created by pooling the assets of Kokusai Tsu-un KK (International Express Co., Ltd.), which consolidated many of the nation's small-scale rail transport companies, and six other competitors, with additional funding from the Japanese government. As World War II progressed, the need for a centralized approach to transport deepened throughout Japan, and the government combined the transportation companies operating in all of the nation's major cities into what would later become Nippon Express. In 1950, under the Express Business Act and the Commercial Law Act, the company was relaunched as a private concern. Since that time, Nippon Express has expanded and developed its business in tandem with the Japanese economy as a whole.
