There are two islands in the Sea of Japan, "Matsu sima (Dagelet I.)" and "Liancourt In. (d. Franzosen) - Hornet In. (d. Englander)". These two islands were painted in red, the same colour as Japan. Notice the red line between Japan and Korea which shows the national border. Both "Matsu sima" (Ulleungdo) and "Liancourt In." (Liancourt Rocks) are in the Japanese territory.

This map also has two islands "Matsu Schima" and "Liancourt R." in the Sea of Japan but the map didn't show the national ity of these islands - no colour difference between Japan and Korea (both of the country were painted in yellow), no national border drawn.
