In an effort to prevent human rights abuses in the workplace, a law was enacted Friday to improve supervision of companies that accept foreign workers under a government program.

The move comes after the government decided recently to include nursing care in the list of industries in which foreign trainees can work under the Technical Intern Training Program, following the related legislation's passage through the Upper House.

The change is expected to lead to an increase in the number of foreigners working as nursing caregivers in Japan, where demand for such services is expected to grow as the population grays.
