PROBLEM TO BE SOLVED: To provide a photographing position specifying system, a photographing position specifying device, and a photographing position specifying method capable of precisely obtaining the position of photographing an image even in an environment where GPS cannot be utilized. SOLUTION: The photographing position specifying device 10a includes: an input section 11 for acquiring a photographing instruction; a photographing section 12 for photographing an object when the photographing instruction is acquired; a storage section 17 for storing positions of at least three terminals in advance; a light emitting section 13 emitting light when the photographing instruction is acquired; a sound wave reception section 14 for receiving a sound wave transmitted from each terminal; a time acquisition section 15 for acquiring the time when the sound wave is received and the time when the light is emitted; and a control section 16 for calculating the distance to each terminal on the basis of the difference between the time when the sound wave is received and the time when the light is emitted and specifying the position of the own photographing position specifying device on the basis of the distance to each terminal. The storage section 17 stores the photographing image by the photographing section 12 and the position of the own photographing position specifying device 10a calculated by the control section 16 in association with each other.
