Datsun is an automobile brand owned by Nissan. Datsun's original production run began in 1931. From 1958 to 1986, only vehicles exported by Nissan were identified as Datsun. By 1986 Nissan had phased out the Datsun name.
In 1931, Dat Motorcar Co. chose to name its new small car "Datson", a name which indicated the new car's smaller size when compared to the DAT's larger vehicle already in production. When Nissan took control of DAT in 1934, the name "Datson" was changed to "Datsun", because "son" also means "loss" (損 son) in Japanese and also to honour the sun depicted in the national flag – thus the name Datsun: Dattosan (ダットサン Dattosan). Nissan phased out the Datsun brand in March 1986. The Datsun name is internationally well known for the 510, Fairlady roadsters, the Fairlady (S30 240Z, 260Z, 280Z) S130 280ZX coupes.
