1960 Apr 27 - American Ambassador says Takeshima is Japanese territory, not Korean

On 27th April, 1960, American Ambassador Douglas MacArthur II sent telegram to J. Graham Parsons, Assistant Secretary of State for East Asian and Pacific Affairs, in Washington, and in it, he says that “Therefore we should also press new ROK regime to return Takeshima to Japan.” We already knew that U.S. warned ROK that Takeshima is Japanese island in both 1951 and 1952.

Seoul for Ambassador McConaughy

Now that we have prospect of new and democratic regime in Korea I strongly recommend that as soon as possible we seize opportunity to try to bring about durable solution to ROK-Japan dispute. As long as Rhee held power there seemed little chance of any solution but now we have entirely new situation which could lead to liquidation of ROK-Japan controversy. Implications of ROK-Japan dispute are not just bilateral between GOJ and ROK but deeply and directly involve US and our inescapable solution is to be found it will be produced only by our good offices and working closely with both ROK and GOJ. It is of utmost importance that we identify and be prepared to move swiftly for solution those specific ROK-GOJ problems which prevented progress toward basic settlement this festering dispute. We do not know what response Communists may make to new ROK regime and it is vital we try to put ROK-GOJ house in order as soon as possible.
 
Telegram from D.MacArthur to SECSTATE in1960_2While Rhee regime violated most basic tenets of democracy in authoritarian police rule imposed on Korean people, it has also in past done violence to most fundamental principles of international conduct and morality by committing acts of piracy on high seas around Rhee Line and then imprisoning and holding as political hostages Japanese fishermen and by seizing and holding non-Korean territory by force. The uncivilized practice of hostage diplomacy is one of our serious charges against Communist China and if continued by ROK it will be a great liability to a new democratic ROK regime.


I therefore recommend strongly that as soon as new regime is in control in Korea (whether or noti it be of interim character) we use all our influence to persuade it (1) to release and return to Japan all repeat all Japanese fishermen hostages (including those who have not completed their sentences) who have suffered so cruelly from Rhee’s uncivilized and oppressive acts and (2) to cease practice of seizing Japanese fishing vessels on high seas. This would not only rid new ROK reegime of liability of practicing hostage diplomacy but also more than anything else would lay foundation in Japan for really fruitful negotiations. At same time I would be prepared to press Kishi and GOJ most strongly that in return for repatriation of all fishermen, Japanese would exercise self-restraint in their fishing operations in Korean Straits until reasonable opportunity had been given for negotiation of mutually agreed ROK-Japan fishing conservation agreement.

Telegram from D.MacArthur to SECSTATE in1960_3In addition to seizing Japanese boats on high seas and practicing hostage diplomacy, Rhee regime also seized by force and is holding illegally Takeshima Island which has always been considered as Japanese territory. This is very serious and permanent irritant in Japan-ROK relations and there can be no over-all ROK-Japan settlement until this Japanese island is returned to Japan. Therefore we should also press new ROK regime to return Takeshima to Japan. If it is unwilling to do so pending satisfactory conclusion of over-all ROK-Japan negotiations, new regime should at least signify a willingness to withdraw from Takeshima as part of mutually satisfactory settlement of other outstanding issues between two countries. While we should press strongly for return of Takeshima to Japan, if by any chance new regime were unwilling to do so we should, as very minimum, insist that they agree to submit matter to International Court of Justice for arbitration.

Telegram from D.MacArthur to SECSTATE in1960_4Finally, we should inform new regime very clearly that it must be prepared to adjust its relations with Japan on terms of reciprocity, in such matters as diplomatic missions, visits by businessmen and journalists, commercial trade. Japanese have suffered Rhee’s occupation-minded approach for eight years and will be unwilling to accept such indefensible treatment from his successor. In its own interests, new regime should start with conformity with normal international standards of conduct, and could most usefully begin (in terms of Japanese and other free world opinion) by permitting Japanese diplomatic mission to enter and function in ROK on same terms ROK Embassy operates here.

If we now move swiftly with new ROK regime which should generally be receptive to our views because of our helpfulness, we may have initial opportunity, which may never reoccur, to influence its position on Japan-ROK problem. Japanese would certainly welcome warmly and reciprocate fully, measures indicating new ROK regime willing take “new look” at Japan.

Asahi Shimbun - "Takeshima issue explained in Q&A format"

Below is an August 16, 2012 article from the Japanese newspaper Asahi Shimbun. LINK

It is a pretty good article, but it oversimplifies the answer to the question, "What about the history?" It fails, for example, to mention that while Japan has numerous maps and documents to support her claim to Liancourt Rocks (Takeshima/Japan), Korea has none to support hers.

Also, how can Korea claim the Rocks were "taken by force" in 1905 when the Rocks had never been part of Korean territory or even had Koreans living on them? In fact, the only way Koreans could get to the Rocks at the time were as deckhands on Japanese fishing boats.
The Asahi Shimbun 
South Korean President Lee Myung-bak's surprise visit to the disputed Takeshima islets on Aug. 10 sent relations with Japan into a tailspin.  
Staff Writer Toru Higashioka attempts to put the issue in perspective in the following question-and-answer format:  
Question: What was the Japanese government's reaction to Lee's visit?
Answer: Both Prime Minister Yoshihiko Noda and Foreign Minister Koichiro Genba lodged strong protests.  
Q: What is the Japan's position with regard to the islets, which are called Dokdo in Korean?  
A: While South Korea claims the islets, Tokyo maintains they are Japan's sovereign territory, both historically and under international law. It also maintains that South Korea is illegally occupying them.  
Q: What is at issue right now?  
A: Lee's visit to Takeshima was an affront to Japan. Here was the leader of a country landing on territory it illegally occupies. His visit was completely unacceptable for the Japanese government.  
Q: Why does Japan maintain that South Korea is illegally occupying the islets?  
A: The 1951 San Francisco Peace Treaty stipulates all territory that Japan should renounce all rights, titles and claims to. But it does not include Takeshima. Then in January 1952, South Korean President Rhee Syngman one-sidedly declared the Rhee Syngman Line, or boundary, on the open sea, putting Takeshima on the South Korean side. South Korea went ahead and stationed security forces on the islets, effectively placing them under its control.  
Q: What about history?  
A: Japan claims it established sovereignty of the islets early in the Edo Period (1603-1867). Takeshima was incorporated into Shimane Prefecture based on a Cabinet decision in 1905. That same year, Japan declared that Korea no longer has diplomatic sovereignty as it moved to annex the Korean Peninsula in 1910. This is why South Koreans regard the islets as having been "taken by force." As a result, the issue has stirred up patriotism and anti-Japan sentiment among South Koreans.  
Q: How has Japan coped with the problem?  
A: In 1954 and 1962, Japan proposed to South Korea that the dispute over sovereignty be referred to the International Court of Justice. But South Korea rejected the idea. So far, Japan has refrained from taking the matter to the court out of consideration for its peaceful relationship with South Korea. Past attempts by Japan to resolve the issue in the ICJ were met with strong opposition from Seoul.  
Q: In spite of all this, Lee went ahead with the visit, didn't he?  
A: Genba said Japan no longer needs to give South Korea's stance on the issue any consideration and can go ahead with filing a suit with the ICJ.

Japanese Unhappy with South Korean President's Visit to Liancourt Rocks (Takeshima/Dokdo)

"Hey, look at us! We got your island. Nayh, nayh, nayh, nayh, nayh!"

2006 Email Informing Me My Teaching Contract Would Not Be Renewed Because of Dokdo Postings

The screenshot to the left is of a December 22, 2006 Email I received from the English Department Head at Gachon University in Incheon, South Korea, where I worked as an English instructor for six years. The email informed me that my employment contract with the school would not be renewed for the 2007 school year. The Department Head believed it was because of my Dokdo postings on the Internet. She wrote: "I think there is little doubt that the school made this decision because of the Dokdo problem."

I am posting it because Robert Koehler of The Marmot's Hole has questioned HERE whether the refusal to renew my employment contract was really due to my Dokdo postings. Here is my translation of the Email I received from my department head at Gachon University:
Teacher Gerry, 
Yesterday, I called again to the Dean of Academic Affairs and urged him to quickly make a decision on your contract problem. This morning, at a meeting attended by the president and the deans of the school, your contract problem was discussed, and it was decided that your contract would not be renewed. I was informed by the Dean of Academic Affairs at about 11 a.m. At the time I was on a train to Daejeon to attend an academic meeting, so I could not contact you right away. I am contacting you now after having arrived home just a little while ago. I think there is little doubt that the school made this decision because of the Dokdo problem. It also hurts me to have to relay this news.
The English Department at the school had two Korean professors and two foreign instructors, including me. In addition to getting the above Email from the Korean professor who was the department head, I also secretly recorded the other Korean professor telling me in both Korean and English that she was in the room arguing that my contract be renewed when the Dean of Planning told her "The Dokdo problem is just too big" to renew my contract. The Dean of Planning had told me just a month or two earlier that I did not have to worry about not being rehired.

Soon after I posted the news on the Internet, I got a call from a Korea Times reporter asking to interview me. I agreed and met her at the McDonalds at the Sinchon Rotary subway entrance. She asked me to bring the secret recording and the copy of the Email I received. The article she wrote about the interview can be read HERE.

Judge for yourselves.

Korean Soccer Player Denied Medal After Displaying "Dokdo" Sign

According to a New York Times article entitled "South Korean Denied Medal After Political Statement," South Korean soccer player Park Jong-soo was barred from receiving his bronze medal at the London Olympics on Saturday for displaying a Korean sign that read "Dokdo Is Our Land" (독도는 우리 땅). Mr. Park was not on the podium with his teammates at the medal ceremony.

Mr. Park held up the sign after South Korea's 2-0 victory over the Japanese soccer team.

The article said that Mr. Park faces investigations by both the International Olympic Committee and FIFA, soccer's governing body, because both organizations strictly enforce rules forbidding athletes from making political statements on the field.

Man Rams 1-ton Truck into Gate of Japanese Embassy in Seoul

At 4:55 a.m. on July 9th, a 62-year-old man from Seongnam City, South Korea drove a 1-ton truck into the front gate of the Japanese Embassy in Seoul, South Korea. Attached to the truck was a sign that read, "Dokdo Is Our Land." The man has been arrested.

(Photo from Joong-ang Ilbo Article HERE)

According to Seoul police, there were no injuries, but the front gate of the embassy has been pushed in about one meter.

The man told police that he was protesting a recent incident in which a Japanese man videotaped himself standing next to a "Comfort Women" memorial in front of the embassy with a stick that read, "Takeshima is Japanese Territory." Takeshima is the Japanese name for Dokdo, a small group of rocky islets that is the subject of a territorial dispute between Japan and South Korea. South Korea has illegally occupied the islets since the 1950s.

According to THIS Wall Street Journal blog article, police said the man had a hand-written note in his pocket that read as follows:
“... driving a stake at the comfort woman’s statue is doomed to God’s wrath. If I die please cremate me and scatter my ashes in the waters near Dokdo.”
The name "Comfort Women" was a euphemism that was once used by both Koreans and Japanese to refer to prostitutes, especially prostitutes for the military. Japan provided comfort women for its troops during World War II, and South Korea provided them for Korean and UN troops during the Korean War and beyond. The Korean newspaper Dong-a Ilbo reported in an October 1959 article HERE that there were 261,089 "comfort women" working in Korea in 1959 and that 66% of them were infected with a venereal disease.

Korean students only scream and yell "Dokdo is our land," but cannot explain why.

This Korean instructor is complaining that the Japanese are winning the international opinion war for their claim to "Dokdo" (Liancourt Rocks - Takeshima) because they can logically explain the reasons for their claim and are doing so in several different languages. He says that Korean students, on the other hand, only scream and yell "Dokdo is our land," but are unable to explain why. The instructor predicts the world will consider "Dokdo" to be Japanese territory within thirty years time.

What happens in Korea if you disagree with its Dokdo claim?

Today I clicked on a link that took me to the Dokdo Research Institute Web site where I decided to check out their Open Discussion Board. There I found a post HERE dated January 4, 2012. Here is the translation of that post:
The Usando shown on an old document is Jukdo?? 
http://blog.naver.com/royalty1234  
The Bulletin Board of this person's blog says that Dokdo is Japanese territory. If you go in and look at it, he claims that the Usando shown on an old document is Jukdo. He shows various materials to support his claim. The material he uses is wrong, and his claim is wrong. I urge to you refute them.
If you click on the link to the offending blog, you now get a message from the blog provider, Naver, that reads as follows:
This is a Closed Blog. Access to this blog has been restricted by request of the Korea Communications Standards Commission.
Old Korean documents show Usando (于山島 - 우산도) to be Ulleungdo's neighboring island of Jukdo (竹島 - 죽도), which is only about 2 kilometers off Ulleungdo's east shore. However, Koreans generally claim that "Usando" was the old name for "Dokdo" (Liancourt Rocks). Apparently, in Korea, one is not allowed to disagree with the general Korean claim.

The Lesson: "Don't use a Korea-based internet service provider to create a blog refuting Korea's claim to 'Dokdo' because opposing opinions are apparently not allowed."

The following are the screenshots of the bulletin board post on the Dokdo Research Institute Web site and of the message from Naver saying the blog is closed.

Japan Probe: "New Jersey Japanese School Wins Takeshima Lawsuit"

A lawsuit brought against a Japanese School in New Jersey for teaching that Takeshima (Dokdo) is Japanese territory has been dismissed. A Korean-American who did not like the school's using a Japanese Social Studies textbook that taught Takeshima (Dokdo) was Japanese territory filed a lawsuit against the school last year. You can read more about the lawsuit in English at "Japan Probe" HERE.

You can read the legal decision HERE.

Japanese readers can read about it in Sankei News:

A Korean translation can be read at the KJClub HERE by clicking on 韓国語で表示.

In the footnotes of her legal decision, the Judge wrote the following:
As a former civil mediator, it would certainly be tempting to suggest that this historic Asian-Pacific dispute, which apparently remains the cause of wide-ranging emotions and politics on both sides, be settled through a designation of one islet to each country. Clearly, if the solution were that simple, it would have occurred before today.

1869? Map of Korea - "東國八域山川一綂全圖." Shows Ulleungdo with a neighboring island labeled "Udo" (于島)

The following Korean map is entitled "Dongguk Pal Yeok San Cheon Il Tong Jeondo" (東國八域山川一綂全圖), which means "Complete Map of All Eight Regions of Mountains and Streams of the Eastern Country." The map is believed to have been made in 1869 and is houseed in the Library of Congress of the United States. LINK

One of the interesting things about the map is that it shows the island of Ulleungdo (鬱陵島 - 울릉도) with a neighboring island labeled "Udo" (于島 - 우도), which was one of the old names for Ulleungdo's neighboring island of Jukdo (竹島 - 죽도), a small island just two kilometers off Ulleungdo's east shore.

Later 1800s - "Takeshima Map Explanation" (竹島圖說) Kensaku Kanamori - "文鳳堂雑纂"

The following comes from a Japanese text entitled "A Compilation of Topics by Bun Ho Do, Vol. 16" (文鳳堂雑纂 - 十六), which seems to have been a volume compiled sometime before 1886 by  Kensaku Kanamori (金森謙建策).

One reason I am posting this text is that I think it was mentioned in an 1876 letter entitled "Concerning Matsushima 2," by Watanabe Kouki (渡辺洪基), who was Director of the Bureau of Documents in Japan's Ministry of Foreign Affairs at the time. Mr. Watanabe was trying to determine if the Japanese name Matsushima (松島) was being used to refer to the Korean island of Ulleungdo (鬱陵島) or to some other island. Another reason I am posting it is that it seems like a very interesting text.

Traditionally, the name "Matsushima" or "Oki's Matsushima" was used by the Japanese to refer to Liancourt Rocks, but Mr. Watanabe suspected that it was also being used to refer to Ulleungdo. In the text, Ulleungdo is referred to as "Takeshima" (竹島) and Liancourt Rocks as "Oki Domain's Matsushima" (隠岐国の松島).

The following is the referrence to the Kensaku (金森謙) text from Mr. Watanabe's 1886 letter:
又金森謙ノ書ニ竹島周圍大凡十五里トアリ 
Also, in the text by Kensaku (金森謙), the circumference of Takeshima was written as 15 ri.
(Mr. Tanaka's Web site is the source of this text HERE.)
Takeshima Map Explanation (竹島圖說)  
In the text “ A Record of the Land of Japan” (日本風土記), “TA (他) KE (計) JI (甚) MA (麽) refers to Takeshima (竹島).   
The family of Kitazono (北園子家), a retired retainer of this Domain, has a text of his entitled “Takeshima Map Explanation” (竹島圖說), in which this family’s ancestor, Mr. Tsuuan, (通葊氏) recorded old stories during the Hohreki Era (1751 – 1764) that were passed down among the people of Inshu (因州). So little is known about it/them that this book can, indeed, be called a treasure.  
I also recorded the story of an oarsman from Iwami (石見). His name was Chozo ((長蔵), from the village of Hamada (濱田). He still lives in Bittyu Province (備中), but is temporarily staying in the town of Obara/Kobara (小原街). (This town may have been what is now the neighborhood of Obara (小原町) in the village of Kasubuchi (粕淵村) in the Ohchi District of Iwami Province (石見囯.)  
These stories are passed down, but I have added to them. I hope this helps those interested in learning about the geography of Takeshima.  
Written by Kanamori Ken Kensaku (金森謙建策 題)  
As for the map of the island, I have made a copy and attached it.  
Someone told me that an essay by Itoh Tohgai (伊東涯) said that the Island of Jikuro (軸羅島) in the Book of Sui(隋書) must be this Takeshima. According to the essay, the circumference (of the island) was 40 ri. I believe his view is probably correct.

.
There is an island called Takeshima about forty ri to the north of the west island of Oki Province’s Matsushima (隠岐國松島ノ西島). (West Island is part of Matsushima and is called “Next Island” by the locals.) The island borders on Japan and is next to Korea. 
They say that it is about forty ri by sea from Takeshima to Korea. This is based on the story of an old man who in 1724, the 9th year of Kyoho (亨保), testified that he had previously traveled to the island several times. When asked he said, “The distance from the village of Mitsuyanagi (三柳) of Hamanome (濱野目) in Aimi County (會見郡) of Houki Province (伯州) to Oki’s Dogo Island (隠岐ノ後島) is between 35 and 36 ri. Using this distance one can guess the distance from Takeshima to the mountains of Korea to be about 40 ri since it seems a bit farther. I suspect that “mountains of Korea” was referring to the mountains of Ulleungdo. The island is triangular in shape and has a circumference of about 15 ri. (It says 15 ri, but that is a rough measurement.)

According to the oarsman (from Iwami), the length from east to west is longer than the length from north to south. Also, there is so much bamboo and so many trees that there are many places that are difficult to enter very far. 

There are many products on this strange island. Near the southeast corner of the island is a place everyone calls Old Port Osaka (古大坂浦), where there is a large bamboo grove with bamboo as large as 2 feet in circumference. To the west of this port is Port Hamada (濱田浦). In between there are two small streams. The source is a waterfall (taki) in the mountains that flows out and joining a river to the east before splitting into three streams that flow into the sea. Among these three streams the middle one is said to have many "sweet fish" (ayu). (The Chinese for ayu is 香魚.)

Also, a little to the west of Port Hamada (濱田浦) is Port Take (竹浦), which is a convenient place to moor boats. However, when the southern wind is servere, it is hard to keep ships tied, so most people house their boats on shore. To the west of this port is a large river that flows into the sea. To the west of the river is a small stream that flows into the river. To the west of that is an island, the name of which I still do not know. To the west of the island is a small stream which seems to be a source of the river to the east instead of a waterfall in the mountains.
To the west of the small stream is Port Northland (北国浦), and a little north of there is Port Willow (柳浦). A little north of Port Willow (柳浦) is another stream, which is fed by a small stream to the east, increasing its size.

The northern bank of this stream connects to a field of reeds. Far to the east of there is an area called Port Osaka (大坂浦).

Also, in the center of the island, in the mountains a little to the east of the waterfall, there is a spring with clear water that tastes sweet. It is said that it produces about two 升 per day. I suspect it is a similar to so-called "sugar-sweetened water" (甘露水).
"It is about 140 ri by ship from Yonago in Houki Province (伯州米子) to Takeshima. You can sail from Yonago to Izumo (出雲) and then on past Oki’s Matsushima (隠岐丿松島) to reach Takeshima. However, it is said that it is about 60 ri by ship from Oki’s Fukushima (福島), also called Fukuura (福浦), to Matsushima, and then about 40 ri from Matsushima to Takeshima. Moreover, it is about 40 ri from Takeshima on to Korea."

The above account was the response from Yonago residents Kyuemon Oya (大谷九右衛) and Ichibee Murakawa (村川市兵衛) to a 1724 inquiry from the Shogunate."

People call this island Takeshima, which is 70 ri from Oki Province. It's circumference is about 16 ri. It has many streams. 
自隱岐國七十里而有此嶋俗号竹島是也 嶌之廽リ大槩十六里 百大河 


Japanese know that Takeshima is located in the sea north of Oki Province. A fisherman from Houki Province (伯耆州) first started fishing there. This island is very near Korea, but previously Koreans did not know of the island. About 3 ri north of this island is another island where there are a great many superior quality abalone. Therefore, it is said that Koreans are sent to the island once every 3 to 5 years to harvest the abalone. At one time Koreans did not know of Takeshima, but in the spring of 1692, they drifted to the island and learned of it for the first time.  
This story is accurate since it was given as testimony by Houki Province fishermen and others at hearing in April 1693.

.... 1. We set sail from Yonago (米子) on February 11 in the 5th year of Genroku (1692) and arrived at Port Fuku (隠岐國 福浦) in Oki Province on the last day of the month. We set sail from Port Fuku on March 24 and landed at Takeshima’s Ika Island (竹島ノイカ島) at about 8 o’clock in the morning on the 26th. We noticed that someone had been fishing there. We had never seen this before.

On the morning of the 27th, on our way to the island’s Port Hamada (濱田浦), we saw two foreign ships. One was anchored and the other was floating. We saw about thirty foreigners on the floating vessel, which was about 8 to 9 ken (間) from us as we passed and turned toward Port Osaka (大坂浦). One man was on shore. He boarded a small boat and came to the side of our ship.
 
When we asked, he answered he came from the Korean village of “Kawaten” (カワテレカワラ). He spoke our language well as if he was an interpreter. Then when we demanded to know why they were harvesting the abalone, he said, “We did not originally plan to harvest abalone on this island. There is an island to the north of here where there is lots of good quality abalone. We travel to that island once every three years by the order of the Korean king. This year we were again headed for that island, but met an ill wind that caused us to drift here."

Then we said,
 "This is Takeshima, and Japanese have been coming here to harvest abalone since long ago, so you must quickly leave." He said the storm they met had completely destroyed their ship and that they would leave as soon as they repaired it, but they did not seem to be in a hurry to leave.
 When we we arrived, we first checked the hut we had previously built. (We kept boats, fishing gear, and other equipment there.)
元禄五年、春二月十有一日、例年ノ如ク米子ヨリ出帆シテ隠岐國福浦ニ著シ、同三月廿四日、福ウラヲ出帆シテ、同月廿六日、朝五時、竹島ノイカ島ト云処ニ着ス。是時、初メテ異邦ノ人、魚猟スルヲ見タリ。蓋、先之、未タ嘗テ見サル処ナリ。翌廿七日、我舟ヲ同島ノ濱田浦ニマハシシトスル海路ニ於テ、又異人舟二艘ヲ見タリ。但、一艘ハ居船ニシ、一艘ハ浮ヘテ、異国人三十人許、之レニ乗セリ。我舟ヲ八九間隔テ、大阪浦ニ廻ル。其人員ニ属スルモノカ一人、陸ニ遣リ居タルカ、忽チ小舟ニ乗シテ我近傍ニ来ル。因テ、之ニ問フニ、朝鮮ノ「カワテンカハラ」の人氏ト答フ。但、此人ハ象胥(ツウジ)ニ似テ、能ク我カ国語ニ通セリ。而シテ那ノ蚫猟ノ故ヲ詰ルニ、彼答ニ曰、原ヨリ此島ニ蚫ヲ猟スルノ意ナシ。然トモ此島ノ以北ニ一島アリテ、上好ノ蚫最多シ。是故ニ、吾儕朝鮮國王ノ命ヲ奉シテ、三年毎ニ一回、彼島ニ渡レリ。当年モ又、那島ニ渡リ、帰帆の路、難風ニ逢ヒ、不計此島(竹シマ)ニ漂泊スト云。尓時、我輩曰、此竹鳥ハ昔時ヨリ、日本人蚫猟を做シ来レル処ナレハ、速ニ出帆スヘシト云ハ、彼カ答ニ、難風ニ邁ヒ、舟皆損坏セルカ故ニ、之ヲ造補シテ後去ルヘシト説ケドモ、其実ハ急ニ退クヘキノ状態ニ非ス。我輩乃上陸シテ嘗テ築造セル小屋(猟船猟具其外雑具ヲ置)


We found that eight boats were missing. We asked the interpreter about this. He said that they had been sent to the other inlets. Furthermore, we very much wanted to go ashore, but there were so many in their group and so few in ours that we did not dare to try it.
Therefore, we departed Takeshima at 7 o'clock in the evening of March 21. However, we gathered  some shewered abalone, a Korean hat, a fermented soybean cake,  and some miso noodles as evidence we had traveled to the island. On April 1st, we arrived at Hamada (濱田 in Iwami (石州), stopped by Kumotsu (雲津) in Izumo (雲州), and returned to Yonago (米子) in Hoki Province (伯州) at 7  o'clock on the 5th day of the same month.

In the last part of February in the 6th year of Genroku (1693), we again set sail from Yonago and arrived at Takeshima without incident on April 17. However, just like the year before, a group of Koreans had arrived and were fishing at will, hindering us, occasionally using rude language, and being disruptive.
We had no choice but to take their leader and two or three of his companions on board our ship. We set sail from Takeshima on the 18th of April and returned on the 28th of the same month to Yonago, where we explained the situation to lord of Hoki Province.
ヲ検査スルニ、猟船八艘ヲ失ヘリ。由テ、之ヲ那ノ象胥ニ質セハ、皆浦々へ廻ハセリト答フ。加之、我舟ヲ居ヘント強レトモ、彼ハ衆、我ハ寡、衆寡固ヨリ敵スヘカラス。恐懼ノ情ナキコト能ハス。故ヲ以テ、三月(元禄五年三月)廿一日晩、七ツ時、竹島ヨリ出帆セリ。但、串蚫(少許)、笠(一个)、頭巾(一个)、味噌麺(一丸)ヲ携ヘ帰レリ。是ハ這回(コノタビ)ノ渡島ノ証ト做シカ為ノミ。四月朔、石州濱田ニ帰リ、雲州雲津ヲ経テ、同月五日七時、伯州米子ニ帰着セリ。

Years before, while Matsudaira Shintaro (松平新太郎) reigned Inshu and Hakushu (因伯両州), Ichibee Murakawa (村川市兵衛) and Oya Jinkichi (大谷甚吉), merchants from Yonago in Hakushu, went to Takeshima (Ulleungdo) to fish and continue to do so today. We have heard that the Shogun (Tokugawa Tsunayoshi) now prohibits voyages to Takeshima. His intention must be kept in mind. We humbly convey this to you.

Toda Takayoshi's (戶田敬義) pre-1876 Map of Ulleungdo - Map A

The following map is one of three maps of "Takeshima" (Ulleungdo) obtained by Toda Takayoshi (戶田敬義) in 1876 or earlier. Another of his maps can be seen HERE. I am calling them Map A and Map B. This Map A looks a little more accurate than Map B. I do not know what happened to his third map.

One of his maps was mentioned in an 1876 letter entitled "Concerning Matsushma 2," which was written by Watanabe Kouki (渡辺洪基), the Director of the Bureau of Documents in Japan's Ministry of Foreign Affairs at the time. In the letter, Mr. Watanabe said that Toda Takayoshi's survey map showed the circumference of "Takeshima" (Ulleungdo) to be about 23 ri, a measure that was calculated by adding up all the measurements of the ins and outs of the shoreline on the map. The reference to the map was as follows:
又戶田敬義ノ圖私船ノ測量ヲ總計スレハ二十三里餘トナル[尤曲屈出入ヲ合セ沿岸]

Also, if you calculate all the survey measurements on Toda Takayoshi's private ship survey map, they add up to about 23 ri. (That measure includes all the ins and outs of the shoreline.)
I posting the map to give people an opportunity to look at it and to comment on it. I will modify the post later after reading the comments and studying the map myself, including trying to determine the circumference of the island. It looks like an interesting map. You can go to the source of the map at Mr. Tanaka's Web site HERE to find a much larger version.

I wonder what happened to Mr. Toda Takayoshi's third map of Ulleungdo.

Toda Takayoshi's (戶田敬義) pre-1876 Map of Ulleungdo - Map B

The following map, entitled "Map of Takeshima" (竹嶌之圖), is one of three maps of "Takeshima" (Ulleungdo) obtained by Toda Takayoshi (戶田敬義) in 1876 or earlier. I only know of two of them, which I will call Map A and Map B. This is Map B, and my post on Map A can be found HERE. You can go to the source of Map B at Mr. Tanaka's Web site HERE to find a much larger version of the map.

One of his maps was mentioned in an 1876 letter entitled "Concerning Matsushma 2," which was written by Watanabe Kouki (渡辺洪基), the Director of the Bureau of Documents in Japan's Ministry of Foreign Affairs at the time. In the letter, Mr. Watanabe said that Toda Takayoshi's  survey map showed the circumference of "Takeshima" (Ulleungdo) to be about 23 ri, a measure that was calculated by adding up all the measurements of the ins and outs of the shoreline on the map. He also said the island in the south corner of the map was probably Uindo (于人島), which was very probably a misspelling of Usando (于山島).

The reference to the map in Mr. Watanabe's letter was as follows:
又戶田敬義ノ圖私船ノ測量ヲ總計スレハ二十三里餘トナル[尤曲屈出入ヲ合セ沿岸] 
Moreover, it you add up all the measurements done by Toda Takayoshi (戶田敬義) on his map they total about 23 ri. (That includes all the ins and outs of the shoreline.) That circumference is more than just a little different than that of Matsushima, or Dagelet. On the south corner of the map is drawn an island that has a circumference of about 1.5 ri. The island is probably Uindo (于人島).

1861 Royal Atas - "China and Japan"

The following map, entitled "China and Japan," is from the 1861 (MDCCCLXI) edition of "The Royal Atlas of Modern Geography," by Alexander Keith Johnston, the Geographer to the Queen of Scotland. The map shows the Korean island of Ulleungdo in the Sea of Japan labeled as "Dagelet or Matsusima." It also shows to the northwest of Ulleungdo the non-existent island of Argonaut, which was the result of a mismapping of Ulleungdo by the British ship Argonaut in 1789.

The reason I am posting the map is that it was mentioned in an 1876 letter written by Watanabe Kouki (渡辺洪基), who was Director of the Bureau of Documents in Japan's Ministry of Foreign Affairs at the time. Mr. Watanabe was researching the location of Dagelet Island, which was the Western name for Korea's Ulleungdo Island, and he used this map as an example of Western maps that showed Dagelet Island at the coordinates 37 degrees 25 minutes N. latitude and 130 degrees 56 minutes E. longitude.

 In his letter, which was entitled "Concerning Matsushima 2," Mr. Watanabe referred to the map in the following way:
英ノロヤールアトラス
Britain's "Royal Atlas"
Mr. Watanabe wanted to confirm the location of Dagelet Island because he suspected the Japanese name "Matsushima" (松島) was being used together with "Dagelet" to refer to Korea's Ulleungdo Island. Traditionally, the name "Matsushima," or "Oki's Matsushima," was used to refer to Liancourt Rocks, which Mr. Watanabe believed to be Japanese territory.

1873 British Nautical Chart of Japan and Korea

The following nautical chart entitled "Preliminary Chart of Japan Nipon, Kiusiu & Sikok and Part of the Korea" was issued by the British Navy's Hydrographic Office in 1873 and was made from British and foreign government surveys done up to 1870. The chart shows Korea's island of Ulleungdo labeled as "Matu sima" with "Dagelet I." in parenthesis. It also shows Liancourt Rocks labeled as "Liancourt Rks.," "Hornet Is.," and "Menelai and Olivutsa." The chart also shows the non-existent island of Argonaut drawn with a dotted line and labeled as "Take sima or Argonaut P.D." The "PD" next to Argonaut means "Position Doubtful."

The reason I am posting the chart  is that it was mentioned in an 1876 letter written by Watanabe Kouki (渡辺洪基), who was Director of the Bureau of Documents in Japan's Ministry of Foreign Affairs at the time. Mr. Watanabe was researching the location of Dagelet Island, which was the Western name for Korea's Ulleungdo Island, and he used this map as an example of Western maps that showed Dagelet Island at the coordinates 37 degrees 25 minutes N. latitude and 130 degrees 56 minutes E. longitude.

In his letter entitled "Second Opinion on Matsushima," Mr. Watanabe referred to the map in the following way:
If we look at Western texts, the British “Imperial Gazetteer” says that Dagelet Island (pronounced as “Dazera”),  or Matsushima, is an island in the Sea of Japan that is situated between the Japanese Archipelago and the Korean Peninsula. Its northwest corner is at 137 degrees (should read “37 degrees”) 25 minutes north latitude and 130 degrees 56 minutes east longitude (Greenwich means). It was named by La Pérouse in 1787. It has a coastline of sheer cliffs and is approximately 9 ri around. It is covered by dense forest up to its highest point.

Also, “Lippincott’s Pronouncing Gazetteer of the World”  says that Dagelet is a small island in the Sea of Japan that is exactly between Japan and Korea. It has a circumference of 8 ri and is positioned at 37 degrees 25 minutes north latitude and 130 degrees 56 minutes east longitude. If you look this up on a map, the location of the island labeled as Dagelet, or Matsushima, on the British Navy’s navigational chart seems to be at the same position as that in both books.
Traditionally, the name "Matsushima," or "Oki's Matsushima," was used by the Japanese to refer to Liancourt Rocks, which Mr. Watanabe believed were Japanese territory, and the name "Takeshima" was traditionally used by the Japanese to refer to Ulleungdo. However, Mr. Watanabe suspected that the name "Matsushima" was now also being used to refer to Ulleungdo, a suspicion the following British navigational chart seems to bear out. Since the name "Takeshima" had always appeared to the west of  "Matsushima" on old Japanese maps, people must have assumed the non-existent island of Argonaut was Takeshima, Korea's Ulleungdo. Therefore, since the real Ulleungdo was now labeled Matsushima, many Japanese and others believed it to be Japanese territory.

1873 British Map - "The Islands of Japan," by James Wyld

The following map entitled "The Islands of Japan" was made in 1873 by James Wyld, the Geographer to the British Queen. The title of the map is "The Islands of Japan." (SOURCE)

The reason I am posting the map is that it was mentioned in an 1876 letter written by Watanabe Kouki (渡辺洪基), who was Director of the Bureau of Documents in Japan's Ministry of Foreign Affairs at the time. Mr. Watanabe was researching the location of Dagelet Island, which was the Western name for Korea's Ulleungdo Island, and he mentioned this map as an example of Western maps that showed Dagelet Island at the coordinates 37 degrees 25 minutes N. latitude and 130 degrees 56 minutes E. longitude.

In his letter, which was entitled "Concerning Matsushima 2," Mr. Watanabe referred to the map in the following way:
英女王地理家ゼイムスウイルドノ日本朝鮮図
"Map of Japan and Korea," by James Wyld, Geographer to the British Queen
The map shows the island of Ulleungdo labeled as "Matsusima / I. Dagelet" and Liancourt Rocks labeled as "Hornet I.s." It also shows Argonaut Island, which was a non-existent island that came about after the mismapping of Ulleungdo by the British Navy in 1789. It is labeled as "Argonaut I. 1789" on the map. Also, Ulleungdo's neighboring island of Jukdo (2 km offshore) is labeled "Boussole Rk," and a rocky islet at the southern tip of Ulleungdo is labeled "Seal I."

Traditionally, the name "Matsushima" or "Oki's Matsushima" was used by the Japanese to refer to Liancourt Rocks, which Mr. Watanabe believed were Japanese territory, but he suspected that the name "Matsushima" was also being used to refer to Ulleungdo, as Mr. Wyld's 1873 map seems to show. In 1880, the Japanese government finally sent a survey ship to Ulleungdo, where it confirmed that the Matsushima on Western maps was, in fact, Ulleungdo.













1872? Royal Illustrated Atlas - "Islands of Japan"

The following map is entitled "Islands of Japan" and comes from what is believed to be an 1872 edition of "The Royal Illustrated Atlas," which was a British atlas. None of the maps are dated, so the date of the atlas was estimated by using the map of Australia. Also, the map of the United States does not show the state of Colorado. The maps in the atlas are believed to date from 1864 to 1872. You can read more about the map and the atlas HERE. The introduction of the atlas describes the "Islands of Japan" map as follows:
Japan, Mandshuria (showing the course of the Amur River), The Kurile Isles, & c.; according to the British and Russian Admiralty Surveys, Krusenstern, Siebald, & c. By John Bartholomew.  
Section Map.--Port of Nagasaki in the island of Kiou-Siou.  
Illustrations. (1.) View of the Port of Simoneseke, Japan. (2.) Japanese Nobleman and Fisherman. (3.) Japanese women of the higher and lower class. By John Dunlop
The reason I am posting the map is that I think it was mentioned in an 1876 letter written by Watanabe Kouki (渡辺洪基), who was Director of the Bureau of Documents in Japan's Ministry of Foreign Affairs at the time.  Mr. Watanabe was researching the location of Dagelet Island, which was the Western name for Korea's Ulleungdo Island, and he mentioned a map from "The Royal Atlas" as one example of several Western maps that showed Dagelet to be at the coordinates 37 degrees 25 minutes N. latitude and 130 degrees 56 minutes E. longitude.

Mr. Watanabe's letter was entitled "Concerning Matsushima 2, and the Japanese reference in the letter to the atlas was as follows:
英ノロヤールアトラス
Britain's "Royal Atlas"
Mr. Watanabe wanted to confirm the location of Dagelet Island because he suspected the Japanese name "Matsushima" (松島) was being used together with "Dagelet" to refer to Korea's Ulleungdo Island. Traditionally, the name "Matsushima" or "Oki's Matsushima" was used to refer to Liancourt Rocks, which Mr. Watanabe believed to be Japanese territory.

Though it is not 100 percent certain that Mr. Watanabe was referring to this map in his 1876 letter, it quite possible he was since this map does show Dagelet Island in the Sea of Japan. The map also shows an island labeled as "Argonaut," which was a non-existent island that came about due to a mismapping of Ulleungdo by the British Navy.

1875 Brue "Atlas Universel," China, Korea, & Japan

The following map, entitled "Carte Générale de L'Empire Chnois et du Japon," is from the 1875 edition of the "Atlas Universel De Geographie Physique," a French atlas with its authors listed as A. H. Brue and E. Levasseur. The map is entitled "Carte Generale de l'Empire Chinois et du Japon" and shows the counties of China, Korea, and Japan. You can read more about the map HERE.

The reason I am posting the map is that it was likely mentioned in an 1876 letter written by Watanabe Kouki (渡辺洪基), who was Director of the Bureau of Documents in Japan's Ministry of Foreign Affairs at the time. Mr. Watanabe was researching the location of Dagelet Island, which was the Western name for Korea's Ulleungdo Island, and he most likely referred to this map as an example of Western maps that showed Dagelet Island at the coordinates 37 degrees 25 minutes N. latitude and 130 degrees 56 minutes E. longitude.
In his letter entitled "Concerning Matsushima 2," Mr. Watanabe Mr. Watanabe referred to the map in the following way::
佛ブルーエノ大圖)
"Atlas Universel," by Brue of France
The map below shows an island labeled as "I. Dagelet," and an island labeled "I. Argonaut." Dagelet was referring to Korea's Ulleungdo, and the island labeled "Argonaut" did not exist because it was just a mismapping of Ulleungdo by the British Navy in 1789.

Traditionally, the name "Matsushima," or "Oki's Matsushima," was used to refer to Liancourt Rocks, which Mr. Watanabe believed to be Japanese territory, but he suspected that the name "Matsushima" was also being used to refer to Ulleungdo.
