A notification device that gives notification of predetermined information can be used more conveniently. A notification device includes a state detecting section, a guidance notifying section, a determining section, and a notification control section. The state detecting section sequentially detects a face state of a subject on the basis of images which are sequentially input. The guidance notifying section gives notification of face guidance information. The determining section determines whether or not the face state sequentially detected by the guidance notifying section satisfies a state corresponding to the notified face guidance information. In a case in which the determining section determines that the state corresponding to the notified face guidance information is satisfied, the notification control section controls the guidance notifying section such that another face guidance information different from the notified face guidance information is notified.
