Japan's Health, Labor and Welfare Ministry will examine the operation of Internet-based babysitting services, following the arrest of a man suspected of abandoning the body of a toddler in his care.

Ministry officials will look at the number of agencies mediating online babysitting and how they connect sitters with clients.

The ministry will then advise parents to confirm on its website whether an agency is insured and keeps records on its babysitters.

Babysitters are currently not required to register with local governments, and there is no law regulating agencies that provide this service.
