It was renamed to Kaishinsha Motorcar Co., Ltd. in 1918, and again to DAT Jidosha &amp; Co., Ltd. (DAT Motorcar Co.) in 1925. DAT Motors built trucks in addition to the DAT and Datsun passenger cars. The vast majority of its output were trucks, due to an almost non-existent consumer market for passenger cars at the time, and disaster recovery efforts as a result of the 1923 Great Kantō earthquake. Beginning in 1918, the first DAT trucks were produced for the military market. At the same time, Jitsuyo Jidosha Co., Ltd. (jitsuyo means practical use or utility) produced small trucks using parts, and materials imported from the United States.
