A random thought for no reason at all: When japanese car companies want to sell cars in the US they don't just build them there. They have design teams creating variants and whole new models to fit the market.
US cars don't sell in Japan because US carmakers aren't putting in the work. Never mind being the wrong style or type of car; never mind being too large for local roads and parking spaces. Most models on offer don't even come with right-hand steering.
