The purpose is to provide a nautical chart display device which enables a measurement of a distance on an electronic nautical chart, like a measuring method which is performed by using a divider. The nautical chart display device 20 includes a display unit 21, an operation detector 22, a registration processing module 62, and a change processing module 63. The display unit 21 has a screen and displays a nautical chart on the screen. The operation detector 22 detects a touch operation to the screen. The registration processing module 62 accepts two points of the touch operation on the screen, and registers a scale at which a distance between the touched points on the screen matches a distance setting on the nautical chart as an additional scale. The change processing module 63 changes the scale of the nautical chart to the additional scale.
