Although China's economy has been slowing down due to a trade war waged by the United States, hurting not only exports but also domestic demand, such a situation may provide a window of opportunity for Japanese businesses.

As relations between the two Asian nations have improved and Washington has repeatedly voiced wariness about Beijing's geopolitical rise, Chinese people have started to have a favorable image of Japan, several surveys show.

Japanese companies and organizations are expected to seize chances to bolster their businesses especially in the fields of food, clothing, nursing care and the environment, some analysts say. Japanese products and services in such areas are already highly regarded in China.
