The first link forgmouth provides is a document titled 松島巡視要否ノ議 (Regarding the Need for an Inspection Mission to Matsushima), and was written in 1878. It is a paper submitted by TANABE Taichi of the Foreign Ministry stating his opinion against an inspection to Matsushima. He says that Matsushima is Usan, and since Usan is part of Ulleungdo, then it is a part of Chosun, and so any inspection mission would cause unnecessary friction from Chosun regardless of the motive. It is just one side of the debate that was going on. Unlike Korea, in Japan, there are usually pros and cons to any issue. The background for his opinion is the 1877 Dajyokanrei, the document Koreans love to site, which says that “Takeshima and one other island is not Japan’s territory (竹島外一島 本邦無関).” Koreans claim that the one other island is Dokto, but the appended map (http://toron.pepper.jp/jp/take/hennyu/haaa.html), which the Koreans ironically provided as evidence, repeatedly prints the name of Matsushima (“Matsushima is 80 ris to the NW of Fukuura, Oki” 隠岐後福浦ヨリ松島ヲ距ル乾位八十里許 and “Isotakeshima is 40ris NW of Matsushima” 松島ヨリ磯竹島ヲ距ル 乾位 四十里許). Thus, it naturally follows that Matsushima would have not gone unnamed in the document. Rather, the one other island most likely referred to Jukto on the northeast of Ulleungdo. After this 1877 ordinance, there was a debate in Japan as to the inspection of Matsushima in preparation for its incorporation should it be unowned since it was positioned in a strategically crucial location. The very fact that this debate took place also confirms that Japan did not forfeit Matsushima the year before in the 1877 ordinance. The situation at the time is summarized in the documents below:
International situation: The British Occupation of Komundo
The Japanese situation: 松島之議 (Regarding Matsushima) by WATANABE Kouki of the Foreign Ministry in 1878
Since all of you here can read the first one, I will summarize the second one. It says:
In the past, most records have dealt with Takeshima, but few have discussed Matsushima in depth. There is currently a heated debate over whether Takeshima and Matsushima are one island or two different islands, but none have been conclusive. The Tokugawa shogunate has determined that Takeshima is Ullengdo and is Chosun territory. Thus, if Matsushima is indeed Takeshima, then it is Chosun’s, if not, then we must claim it, since it is located at such a critical point in the Sea of Japan, as it lies between our land and the Port Lazareff and both British and Russian ships are passing by it frequently. Reviewing the records, Takeshima aka Argonaut is Chosun’s, and the island we originally called Takeshima is equivalent to Ulleungdo. Then it follows that what we call Matsushima must be the island called Hornet Rocks. However, the West seems to call the original Takeshima as Matsushima and have drawn another Takeshima. While all countries regard the Hornet Rocks as our land and display it as thus in their maps, their views of the Argonaut and Dagelet vary. We are not quite sure ourselves. Thus, there is a need to inspect it to determine their identity geographically. We should bring with us people who have been on Takeshima on the mission to confirm the identity of the islands. This matter must be dealt with immediatelytwo cent at occidentalism
2) The section on “The Japanese Inquiry of Ulleungdo Region’s History” misquotes the Japanese text. The portion in red should not end there but continue to include “ルカ”. Thus, the passage reads, “According to the general map of the eight provinces attached at the head of the 東国興地勝覧 (Korean document established in 1478), there are two islands off the coast of Kangwon-to. The one of the west is called Usan and the one of the east is called Uturyou. Do these islands correspond to the two islands we call Takeshima and Matsushima?”
So contrary to what the site says (“These are what we Japanese call Matsushima (Dokdo) and Takeshima” or “It is interesting to note with this document that although Usando was drawn on Ulleungdo’s wrong (West) side, Japanese were concious of this error and still considered Usando to be Matsushima.”), the Japanese are actually questioning the true identity of the islands and which islands they correspond to on Japanese maps.two cents at occidentalism
This is the original Japanese text of the 1877 Directive：
March 29, 10th year of Meiji (1877)
Response to the request for decision regarding the establishment of territorial rights to Takeshima and one other island in the Sea of Japan brought in the appended document of the Ministry of Internal Affairs.
Hearing that the matter stated on the right has been settled as a result of correspondence between our old government and the government of the country concerned since the landing of a Korean in 1692, and has been declared not to be our territory, and hearing the purport of the request, we have created the following directive and make a decision on the matter.
On the matter of Takeshima and one other island in the purport of the request, it should be considered as not our territory.
So the question is, is the “one other island (外一島)” the present Takeshima, then known as Matsushima or the Liancourt Rocks? I do not think so, because in the original request and in the appended opinions, the name “Matsushima” is explicitly stated and so it would not have gone unnamed in the decision. A Korean newspaper “discovered” a Japanese map (which was available on the Internet and common knowledge in Japan long before) and claims that it had been appended to the directive and is proof that the “one other island” is Matsushima (present Takeshima). Even on that map, the name Matsushima is clearly printed. Contrary to what they claim, the map gives us a hint on what the other unnamed island: Jukto.
Furthermore, what immediately followed after this 1877 Directive was a series of debate on what to do with Matsushima, which clearly would not have taken place had it been included in the directive as forfeited territory. Some, like Tanabe in 松島巡視要否ノ議 (1878), claimed that such in inspection would be mistaken for Japan having territorial ambitions on Korea, since Matsushima was an island belonging to ancient Usanguk of Chosun. Others, like Koki Watanabe (松島ノ議 1878) claimed that it is crucial for Japan to identify the island Matsushima, as if it indeed existed and was unclaimed, it could pose a serious national security threat in the future if taken by foreign countries (I think he had in mind the Russian occupation of Tsushima in 1861). Notice the debate was about the identity of Dagelet Island. The latter side prevailed, and an inspection mission by the Navy vessel Amagi was conducted in 1880. Now why did Japan have to identify Matsushima? Because western maps had confused the situation by mapping three island in the Sea of Japan, from nearest to Japan, the Liancourt Rocks (Hornet Island), Dagelet (Matsushima), and Argonaut (Takeshima). In Edo period Japan, the Liancourt Rocks had been called Matsushima and Ulleungdo had been called Takeshima. Finally, a Japanese inspection mission in 1880 concludes once and for all that Matsushima (Dagelet) is no other than the former Takeshima/Ulleungdo.
Now, as for the passage “Takeshima and Matsushima have both become Chosun territory (竹島 松島 朝鮮附属ニ相成候始末),” it appears in the 1870 document “Investigation on the disposition of diplomatic affairs with Chosun (朝鮮国交際始末内探書, 1870).
Account of Takeshima and Matsushima both having become Chosun territory
This matter concerns Matsushima which is a neighboring island of Takeshima and for no records of which exists up to this date.
Takeshima has been inhabited by Koreans sent by the Chosun government for a while after the Genroku incident [Note: Ahn Yong-bok incident], but since then have become uninhabited as before.
I hear that its produces are bamboo, lumber and reeds thicker than bamboo and that gingseng and other plant products grow naturally on the island. Marine products are fairly abundant.
Note how the document says that there are no records of Matsushima in Japan. If this author had meant the Matsushima/Liancourt Rocks/present Takeshima, then he would have found historical records of it. The Liancourt Rocks have been drawn on Japanese maps as Matsushima since the Edo period, and the shogunate had granted the Otani family development rights of Matsushima, so the “no records” doesn’t make sense. It does make sense if the author had been talking about the Matsushima/Dagelet. There are no records of such a large island between the Liancourt Rocks and Takeshima/Ulleungdo. The Japanese, seeing a western map with three islands, would naturally have been confused to see a large Matsushima/Dagelet between the Liancourt Rocks and Takeshima/Argonaut, the latter which we knew as Takeshima or Ulleungdo in the Edo period. They would have become even more confused since maps like the 1867 KATSU Kaishu map (大日本沿海略図, enlarged on bottom here) clearly showed that Matsushima/Dagelet was more like the Takeshima/Ulleungdo we knew. Basically, this 1867 map was the start of the whole debate over the identity of Takeshima and Matsushima (Argonaut and Dagelet) in Japan, which was settled in 1880.
The fact that Japan forgot to officially incorporate Takeshima until 1905 shows that neither the identity nor the ownership of Liancourt Rocks was even being questioned during these debates, since “All foreign maps show the Hornet Rocks as belonging to us (而テ此ホルネットロックスノ我国ニ属スルハ各国ノ地図皆然リ－松島ノ議1878).”
