There are couple methods to change the game's language in Disney Pop Town.
First, players can change the language at the splash screen before you start playing the game. Look for the language option in the top right corner of the screen and choose the language of your choice.
Another method to changing the game's language is from the game's settings. In the general settings menu button (3 horizontal bars), tap on Settings and then tap the Language button. Choose from a list of available languages.
