In a nutshell, yes but you do use some of your parts like the oil pan, wire harness and ECU.

In Japan there are really strict emissions rules so when a car reaches 45k to 60k miles (72k to 96k kilometers) they have a huge fee at annual inspection so the citizenry trade in the cars that end up being scrapped by the dealer. Parts like engines and transmissions are then sold as exports.
