not all imports have been woundback, When i received my car from the import company that i used, the car had one of these on the windscreen.
they go through all of the records of the car when it was in Japan, aswell as check for evidence of ODO tampering/rollback. and if it passes you will see one of these stickers on the car somewhere. so you can be sure that the odometer reading is 100% genuine.
So, i try to buy imports that have this sticker whenever i can. their website is below if you would like any more info
