Foreigner market

During the period from 2012 to 2017, the number of foreigners living in Japan had increased by more than 530,000. The decline in the workforce of Japanese people had resulted in the annual increase in employment of foreigners as well (about four times compared to 2004). It is also said that in 2020, the number of foreign students studing in Japan will double compared to 2010.

Also, along with the remarkable increase in international students,45.7% of new adults in Shinjuku Ward are foreigners, which has climbed over 1,700 in 2018. In Toshima Ward, 38.3% of new adults are foreigners. And in Nakano Ward, foreign new adults occupies 27% of the whole new adult population.​ ​
Generally speaking, Japanese language schools provide 4 entrance seasons, while universities and colleges provide 2. In this way, you still have chance to have your apartment applied after the moving season.
