In Japan, foreign cars struggle to make a significant impact due to various reasons. Japanese consumers have a strong preference for local brands thanks to their reliability, fuel efficiency, and advanced features. The country's narrow and crowded streets also favor smaller, domestic models. Additionally, Japan's strict regulations and inspections can make owning a foreign car expensive and cumbersome. Lastly, the strong customer service culture in Japan, which foreign brands might struggle to match, also influences the market share.
