Anyone ship Japanese car back to the states on their own and not via military pcs?

I’m just curious what people’s experience is having bought a car in Okinawa and took it back stateside. How much was it; any issues registering; worth it? I have always liked Toyota land cruisers and getting one in Japan would be nice if I could take it back to the states without it costing too much or being too difficult to register.

Any info is appreciated.
