According to the Immigration Services Agency, the number of foreign residents in Japan stood at a record 3.96 million as of the end of June, with permanent residents comprising the largest group at around 930,000, or 23.6 percent, of the total. Currently, a foreigner applying for permanent residency must have resided in Japan for at least 10 years and provide evidence of having the means to support themselves, among other requirements. Given an expected increase in permanent residents in the future, additional requirements such as Japanese language proficiency and mandatory participation in programs that teach community rules, as well as raising the required minimum income have been discussed.
