A small contribution,
Interesting; all Japan standard LCs (made for the Jp market) are very similar to north america's LXs, I had a 1998 100 LC that was as equiped and possibly excceded the US LX470, they even looked identical, and my 2008 200 LC comes standard with some of these whistles; HDD…, they look deferent this time though and on the other side, Jp 200 LCs carry an improved version of the same 4.7L V8 instead of the 5.7.
I am not sure if you are aware of this but the LX570 is pretty much a high end trim level of the Land Cruiser with the lexus badge.
The only thing exclusive to the LX570 is the cosmetics parts like interior, grille and some of the cameras.
In some overseas markets. The Land Cruiser 200 can be had with the same (LX570) adaptive variable suspension, automatic height control, second row power seats and 4.5 diesel engine.
Then in another market, the 200 series comes with KDSS, 4.7, 5 speed auto.
