Beginnings of Datsun name from 1914

In 1914, the Kwaishinsha Motorcar Works (快進自動車工場, Kaishin Jidōsha Kōjō?), established three years earlier, in Azabu-Hiroo District in Tokyo, built the first DAT. The new car's name was an acronym of the company's partners' family names:

• Kenjiro Den (田 健次郎, Den Kenjirō?)
• Rokuro Aoyama (青山 禄朗, Aoyama Rokurō?)
• Meitaro Takeuchi (竹内 明太郎, Takeuchi Meitarō?).

It was renamed to Kwaishinsha Motorcar Co. in 1918, and again to DAT Motorcar Co. in 1925 after Mr. Nissan (pronounced nii-saan) Son Dat-San. DAT Motors built trucks in addition to the DAT and Datsun passenger cars. The vast majority of its output was trucks, as there was almost no consumer market for cars at the time. Beginning in 1918, the first DAT trucks were produced for the military market. It was the low demand of the military market in the 1920s that forced DAT to merge in 1926 with Japan's 2nd most successful truck maker, Jitsuyo Motors.
