1930s

Aikawa soon recognized the excellence of the DAT car and acquired the manufacturing rights. Following mergers, Kwaishinsha became DAT Jidosha Seizo Co., Ltd., and in 1930 the firm built a new compact car. The Datson (son of DAT) then completed a grueling test run between Osaka and Tokyo without a hitch. Its name was changed to Datsun in 1932.

Aikawa then established Jidosha Seizo Co., Ltd., in 1933 to ramp up production. In 1934, the company was renamed Nissan Motor Co., Ltd. The Yokohama Plant — Japan's first automobile mass production facility — launched the following year, and Nissan began exporting cars to Asia, Central and South America and other regions.

The Automobile Manufacturing Industries Act was enacted in 1936 to promote the domestic auto industry, and domestic cars gradually replaced imports on Japanese roads.
