Trust Japanese Vehicles and Autorec export used cars from Japan. Added together, these two companies have more than 2,500 vehicles available through their websites. Both websites offer extensive filters to make searching easier.
Some Japanese cars, such as the 1989 to 2001 Nissan Skyline R32/R34 and the 1991 to 1996 Honda Beat, do not meet the regulations of the National Highway Traffic Administration and are not road legal in the United States. As such, importing them can cause legal trouble.
Similarly, a majority of cars in Japan have the steering wheel on the right side of the dashboard and are usually more challenging to drive in the United States. They are also likely to cost more to get insurance for than cars with the steering wheel on the left side.
