Yes but the Japanese strategy was not "sell at the lowest possible price". It was "we have good control over our costs, let's pick a price and see what we can deliver at that price". At that point in time, US automakers didn't even know what making a car cost them, they were so focussed on revenue they lost sight of the bottom line.
PS: Don't forget the market decides price, you can only really control cost if you want to be more than a nitch player.
