The present disclosure provides a navigational sign identifying device capable of improving an accuracy of identifying description of a sign. The navigational sign identifying device includes a first acquirer, a first identifier, a second acquirer, and a second identifier. The first acquirer acquires a first image including a buoy from a camera installed in a ship. The first identifier identifies a position of the buoy inside the first image. The second acquirer acquires a second image corresponding to a partial area of the first image including the position of the buoy, and the second image is higher in resolution than the first image. The second identifier identifies description of a sign of the buoy based on the second image.
