The Social Insurance Agency is to investigate Japan's largest English-language teaching companies over a suspected failure to enroll their full-time foreign employees in the employees' pension and health insurance schemes.
Japan's largest "eikaiwa" chain, Nova, is already being probed by the Social Insurance Agency and could see itself slapped with a multibillion-yen bill for missed payments.
The agency has been investigating Nova since the end of March and expects to have its results at the end of May or beginning of June.
