The company made the announcement to employees on Wednesday, according to the Wall Street Journal.
A company representative confirmed the report, but noted that there would not be an immediate shutdown.
Toys 'R' Us was already in the process of closing about 180 stores.
In a conference call with employees, CEO David Brandon cited customers choosing to shop elsewhere and online as one of the main reasons for the closures.
Toys 'R' Us returns and gift cards will reportedly be honored for 30 days.
