According to a 2019 survey, 4.4% of foreigners living in Japan who are not enrolled are far higher than the 0.1% of Japanese people in the same age group. That 4.4% is thought to include international students, self-employed people, and technical intern trainees whose places of work do not enrol them in the employee's pension system. This factor affects their enrollment in the national system and how much they contribute to it. The Ministry of Health, Labor and Welfare will revise the Japan Pension Service's systems and obtain data from a nationwide resident register to access information on new immigrants to Japan. Those whose pension eligibility cannot be confirmed will be asked to enrol in the system. If there is no response, the Pension Service will enrol them automatically.
