"We will introduce a new smartphone app customers can use to post their feelings, opinions and requests, aiming at strengthening our ability to listen to customers' voices," McDonald's Japan Holdings said in a statement earlier this week.
The new app will allow users to send complaints directly to the parent company, according to the statement.
The firm also pledged to set up a "voluntary action plan" to improve communication with customers, with details due to be announced in April.
McDonald's Japan is trying its best to save face after an array of reports that its nuggets and burgers were contaminated by various objects including a piece of metal, a human tooth and what some sources identified as "dental material".
The company's same-store sales plummeted 38.6 percent in January and 28.9 percent in February in the wake of the food-safety scandals.
Meanwhile, McDonald’s Japan has already announced the appointment of a new chairman and chief operating officer.
