A bathroom emergency can quickly turn into an embarrassing experience.

But now in Japan there’s an app with an “emergency” button to help you find the nearest bathroom. Unfortunately for visitors, the app is available only in Japanese.

Lion Corp., maker of the diarrhea medicine Stoppa, says the @Toilet app will find the closest bathroom within walking distance once the emergency button is pressed.

The app provides the locations of bathrooms at restaurants, cafes and convenience stores across Japan, including at train stations in Tokyo, Nagoya, Osaka, Fukuoka and Sapporo.

The maker of toiletries and detergents developed the app in 2010. After the March 2011 earthquake and tsunami, downloads surged as people in the affected areas had trouble finding bathrooms.
