ParkYong-hyo (朴泳孝) , the special envoy (修信使) to Japan, again, strongly protested to Count Inoue Kaoru (井上馨), the Minister of Foreign Affairs, when the ratification of the agreement concerning the Jingo Incident (壬午事変) , or the Imo Incident (壬午軍乱) in Korean, was finished in 1882. Inoue corresponded positively and even asked Prince Sanjo Sanetomi (三条 実美), the Dajo(or Daijo) Daijin (太政大臣) or Chancellor of the Realm, for special consideration for a quick arrangement before the Korean mission left Japan.
On March 3, 1883, the instruction named "The Draft of Official Notice" was issued to each of Japan's provinces prohibiting voyage to Ulleungdo .
Draft of Official Notice
The island that Japan calls Matsushima or Takeshima and that Korea calls Ulleungdo, located at 37 degrees 30 minutes north latitude and 130 degrees 49 minutes east longitude, is the island that Japan and Korea had an document of agreement saying that Japanese would not sail to nor land on the island without reason. We hereby notifiy this fact to the director of each local government so that there will be no confusion about it.
March 3 1883
The Dajo daijin
Notice that the Meiji government referred to Ulleungdo as "Matsushima or Takeshima" and that it was located at a latitude of 37 degrees 30 minutes N and a longitude of 130 degrees 49 minutes E, which means that the Japanese government recognized that Ulleungdo was referred to as both Matsushima and Takeshima. The longitude and latitude of the island identifies the island as Ulleungdo, not today's Takeshima (Liancourt Rocks). There is no mention of Liancourt Rocks since Korean government never protested about them, probably because she had little or no knowledge of them.
Liancourt Rocks (Takeshima/Dokdo) had never been an issue between Japan and Korea until 1947, the year that the Korean government suddenly began to claim they were Korean territory even though she had no maps or documents to back up the claim.
