For Chinese people, study abroad is an important matter. During the COVID-19 pandemic, many countries implemented travel regulation policies. Except for the early part of 2020, however, long term residents, including international students, were allowed to enter Japan. Despite the COVID pandemic, some of the degree program students entered Japan from abroad. In addition, as soon as the international travel regulations ended, a huge number of non-degree students including kenkyusei（ research students） and language program students rushed to Japan.
