An endoscope device includes: an insertion unit having segments continuously provided along an axial direction of the insertion unit and configured to be inserted into a lumen a state quantity calculating unit configured to calculate a state quantity of each segment variable rigidity portions provided for each segment to allow bending rigidity of each segment to be variable an origin specifying unit configured to specify an origin segment among the segments in setting a segment range indicating which segment the bending rigidity is to be changed or in setting the bending rigidity, based on the state quantity of each segment and an operation controller configured to: set the segment range or set the bending rigidity of each segment, based on the origin segment and decrease bending rigidities of two or more continuously provided segments based on the set segment range or on the set bending rigidity.
