The present disclosure provides a navigational sign identifying device capable of discriminating a port sign and a starboard sign without depending on a position of a ship. The navigational sign identifying device includes an acquirer, a mode identifier, a country determinator, and a port-starboard determinator. The acquirer acquires an image generated by a camera installed in a ship. The mode identifier identifies whether a mode of a lateral buoy included in the image is either one of a first mode and a second mode. The country determinator determines a country to which a position of the ship detected by a position detector belongs, and the position detector detects the position. The port-starboard determinator determines whether description of a sign of the lateral buoy is either one of the port sign and the starboard sign, from the mode of the lateral buoy and the determined country, based on a given correspondence relationship indicative of whether each of the first mode and the second mode corresponds to either one of the port sign and the starboard sign in each country.
