The number of foreign workers in Japan has been steadily increasing in recent years, especially in urban areas. Among them are international students working part-time and foreigners staying to work in Japan. In this article, we will discuss the actual situation of foreign workers and social conditions in Japan based on official data released by the government. Japan is currently experiencing a declining birth rate. It is estimated that by 2030, 1/3 of the country's population will be aged 65, resulting in a significant shortage of productive labor. Moreover, strong international competition due to rapid globalization could create problems for Japan, unless the Japanese government expands the acceptance of foreign workers. That is why the Amendments to the Immigration Control and Refugee Recognition Act (April 2019) introduced new residence visas namely, “Special Skill 1” and “Special Skill 2”. The introduction of these two special visas is an effort by the state to assist 14 specific industrial sectors that find it difficult to obtain human resources and require special skills but are not too technical and specialized. The goal is for foreign workers to be part of the progress of Japan's manufacturing and service industries. However, these efforts still have not overcome the mountain of problems surrounding foreign workers in Japan. For example, the complexity of the procedure for applying for a work visa, fraudulent companies employing foreigners with low wages, problems arising from differences in culture and values, and various other problems.
