After Trump took office as President of the United States, he began to implement a series of economic policies. He attached particular importance to the development of the automobile industry. First, he drastically aimed at imported cars at home, and now he even pointed to the direction of Japan's breakthrough. Trump angered Japanese consumers to hardly buy American cars and demanded that the Japanese government improve the situation. In order to rejuvenate the U.S. manufacturing industry, Trump will focus on the development of the automotive industry. He hopes that U.S. cars will be sold globally. This includes Japan, of course, but it is no longer true that U.S. car sales in Japan have been poor. New phenomenon. In 2016 alone, about 5 million passenger cars and light trucks were imported into Japan, while only 15,000 were from the United States. The market share was only 0.3%. The Japanese are loyal to their own brands and believe that domestic cars are both reliable and inexpensive, making Japanese cars not only popular in the country, but also in the global sales performance. What is the problem with American cars? It turns out that Japanese consumers think that American cars are easy to damage and not fuel-efficient. They are not reliable transportation tools. Despite the fact that loyal users are redressing this, it is still difficult to eliminate the established impression. In response to this phenomenon, Kobayashi Kenji, executive director of the Japan Automobile Import Association, pointed out that American car manufacturers did not make every effort to persuade consumers, and they rarely saw American cars advertising in Japan, and the U.S. was unwilling to abide by Japanese safety standards. Correcting vehicle body safety equipment shows that American auto makers do not attach importance to the Japanese market. Then how do they require domestic people to pay?
