Japan's Annexation of Dokdo and Korean Objections
The historical facts of the Dokdo - Takeshima Island dispute
When most people are asked when the Dokdo dispute first began they respond it started after World War II when the allies were drawing up international boundaries of former Japanese colonies. In reality, the first documented evidence over this dispute came only days after Chosun officials were notified Japan had annexed Dokdo.This article details how the Korean government and media responded to Japan's first illegal land "acquisition" of Korean territory.

The Japanese Takeshima Inspection Team Arrives on Ulleungdo
(March 28th 1906)
On February 22, 1905, Shimane prefecture announced Public Notice No. 40, naming Liancourt Island Takeshima and placing it under the Chief of Oki Island. The Japanese government did not announce this decision in the official gazette, nor make a public announcement on the central government level. One can cite as a precedent of the Japanese government establishing territorial sovereignty over an island related to foreign countries, the case of the Ogasawara Islands in 1876. At that time, the Japanese government made the decision after negotiating with Britain and the United States which were deeply related with the islands, to win their understanding. Japan also notified 12 European countries and the U.S.A. of its action. 

As for the acquisition of Takeshima/Tokdo which some Japanese thought might belong to Korea, the Japanese government did not make inquiry of the Korean government, much less notify it of the action of incorporation afterwards. Korea learned of the Japan's incorporation in March 1906, one year after the measure was taken. A Shimane prefecture delegation led by an administrative official, Zinzai Yutaro, dropped by Ullungdo after making an inspection tour of Takeshima/Tokdo.
The above picture is the Japanese Takeshima (Dokdo) Inspection Group that arrived on Ulleungdo on March 28th 1906. It was the first time Japanese openly announced they had "incorporated" Dokdo (more than a year after the fact)
The Korean Reaction to Japan's Claim
On March 28, Zinzai Yutaro and his party visited Ullungdo County Chief Sim Hung-t'aek and notified him of the Japanese incorporation of Takeshima/Tokdo. Surprised at the unexpected news, Shim reported immediately to the central government the next day as follows: Mr Shim's quote is boxed in red in the official document below.
Tokdo belonging to this county is located in the sea 100 ri from this county. A Japanese steamship moored at Todongp'o in Udo on the 4th day of the month about 8:00 a.m and a group of Japanese Officials came to my office and said, "We came to inspect Tokdo since it is now Japanese territory..." 

The group included official Zinzai, of Oki Island in Shimane prefecture, Director Yoshida Meigo of the Tax Supervision Bureau, police sub-station chief, Inspector Kageyama Iwahachiro, one policeman, one local assemblyman, a doctor and a technician and about a dozen 'followers, They have come for the purpose of finding out firstly, the number of households, population, and land production, and secondly, the number of personnel and expenditure. The record having being made, we submit this report for your reference. 

Lunar March 5, 10th year of Kwangmu (1906)...."
The paper above records Chosun's opposition to Japan's annexation of Dokdo Island at various governmental levels. The Korean government expressed their objection immediately upon being informed the Japanese had seized Dokdo Island.
Shim Heung Taek was not alone in his opposition to Japan's annexation of Dokdo. Recorded in the paper above are the contentions of the Daehan Empire Governor as well. The Governor's response is highlighted in a blue text box.

"Order No.3 by the Daehan Empires Governor  I have read this report. Their word that Dokdo has become Japanese territory is  a totally unfounded allegation, recheck the island and action of Japanese people...."

The visit to Ullungdo by the Zinzai party was well known, but this data has not been examined in Japan at all. In the dispute with Korea, the Japanese government even doubted the existence of this document itself. As its basis, a Japanese scholar writes that one sea lion caught on Takeshima was presented to the County Chief, who thanked them for the gift. Such a treatment would not have happened if the County Chief had considered Takeshima as I belonging to Ullungdo.

But, that is to ignore the difficult situation Ullungdo was faced with at that time. At this time, Japanese soldiers and police were permanently stationed on Ullungdo and more than 300 Japanese lived in and around Todong where the county office was located. (see pic) The fact that Zinzai and his party investigated at will the number of households, population and geographical features in the foreign territory of Ullungdo graphically illustrates the one-sided power relations of that time. If County Chief Sim did not openly raise objection to Zinzai and his party on the territorial problem, it was due to the pressure from the Japanese. His courteous treatment of the Japanese did not mean that he approved Zinzai remarks. This also does not justify the Japanese denial of this data itself.
Other Korean Objections
The image on the right is from the original news article from the Daehan Maeil Shinbo. The report echoes the information given from the Governor of Uldo County (Ulleungdo Island and area) it also contests the Japanese  Shimane Prefecture Inclusion. It reads as follows:

May 1st 1906 "Uldo governor Shim Heung Taek reported to the Domestic Affairs Office that some Japanese officials came to Ulluengdo Island and claimed Dokdo as Japanese territory, surveyed the island and then counted the number of households. In response to (Shim Hueng Taek's) the report, the Domestic Affairs office  stated  "It is not unusual for those Japanese Officials to inspect Ulleungdo Island while they were traveling in the area. However their claiming Dokdo as Japanese territory does not make sense at all. We find the Japanese claim shocking...."
In Conclusion
The first half of the article merely summarized County Chief Sim' s report, but the second half is valuable in finding out the reactions of the central government. Namely, Korea's central government was recognizing from the beginning that Tokdo was Korean territory .Therefore, it harbors a suspicion of the movement of the Japanese officials who made incomprehensible remarks.

It is certain that many Korean people learned through this newspaper coverage of the Japanese move to incorporate Takeshima/Tokdo into its territory and must have read it as an aggression into Korean territory. For example, Hwang Hyon who lived in Kurye, Chollado, at that time writes in a note that "the Japanese are making a false statement that Tokdo belongs to Japan while it is our own territory...."

In other words, Korea' s central government, local Ullungdo County Chief and civilians all considered Japanese incorporation of Takeshima/Tokdo as aggression at that time. But, by that time, Japan had virtually started colonial rule over Korea, by establishing the Residency-General in Korea.  Evidence of Japan's appropriation of Korean land prior to the annexation of Dokdo can be seen on these links (
link 1),  (link 2),  (link 3).

The documented Japanese Surveys of Dokdo undertaken by the Japanese Imperial Navy can be seen on these pages (
link1), (link 2), (link3). That is why no further development could be made within the Korean government to cope with the problem of Takeshima - Dokdo.

As the entire country was being robbed of its sovereignty and vanishing, the problem of the ownership of a small rocky island was hurled away. However, that the Korean people clearly raised objection to the Japanese action of incorporating Takeshima/Tokdo is a decisively important fact worthy of historical evaluation.
