2009 - 17 July - Japanese Defense White Paper claimed Takeshima is an inherent part of Japan.

17th July, 2009, in a cabinet meeting, the government of Japan approved a 2009 defense white paper(平成21年版 防衛白書) that claimed Takeshima as an inherent Japanese territory. Let's see what it says.

Chapter 1. Security environment that surrounds Japan
2. Security environment around my country
In Asia Pacific region、there are the countries that accomplishes the rapid economic development such as China and India, and a worldwide concern for this region rises mainly from the economic aspect. At the same time, enhancement and strengthening cooperation and the cooperation between each country in the region have been attempted.On the other hand, diversity like the political dispensation and an economic developmental stage, the race, and the religion, etc. is abundant, and in this region it still remains the composition of the confrontation of each country even after the cold war is over. The views on security environment and the recognition on threats are different each other. Thus a big change in the security environment seen in European region has yet to be occurred and a past problem such as territorial issues and unification affairs has been left. In Choson peninsula, the same race's dividing into two parts continues over longer than half a century, leaving the military forces from both countries, north and south, confronting each other. Moreover, addition to the problem over Taiwan, the territorial issue over Spratly Islands exist, too. Furthermore, as for Japan, the territorial issues over northern territories and Takeshima, both of which are the inherent parts of our country, still remain unsettled.

第I部　わが国を取り巻く安全保障環境
2　わが国周辺の安全保障環境 　
アジア太平洋地域では、中国やインドなど、急速な経済発展を遂げている国がみられ、経済面を中心として、この地域への世界的な関心が高まるとともに、域内各国間の連携・協力関係の充実・強化が図られてきている。他方で、この地域は、政治体制や経済の発展段階、民族、宗教など多様性に富み、また、冷戦終結後も各国・地域の対立の構図が残り、さらには、安全保障観、脅威認識も各国によってさまざまであることなどから、冷戦終結に伴い欧州地域でみられたような安全保障環境の大きな変化はみられず、依然として領土問題や統一問題といった従来からの問題も残されている。 　朝鮮半島においては、半世紀以上にわたり同一民族の分断が継続し、南北双方の兵力が対峙(たいじ)する状態が続いている。また、台湾をめぐる問題のほか、南沙(なんさ)群島をめぐる領有権の問題なども存在する。さらに、わが国について言えば、わが国固有の領土である北方領土や竹島の領土問題が依然として未解決のまま存在している。

Korean Government reacted to this promptly and Korean media reported this in Japanese on their news site. Or ordinary Japanese would not have even known about what defense white paper says about Takeshima.

Korea has strongly protested Japan's move to include the country's easternmost islets of Dokdo as Japanese territory in its annual defense white paper. In a cabinet meeting on Friday Tokyo approved a 2009 defense white paper that claimed Korea's Dokdo islets as Japanese territory under the name "Takeshima." Seoul's foreign ministry responded strongly, emphasizing the islets are Korean territory according to history, geography and international law, and demanded an immediate rectification. Seoul also accused Tokyo of raising tensions less than a month after the two countries' leaders held a summit. Arirang News / Jul. 20, 2009 10:34 KST

Now, even North Korean ruling party repulsed as well, claiming "Infringement to my race's autonomy".

北朝鮮の朝鮮労働党機関紙「労働新聞」は２８日、日本の２００９年版防衛白書が、北朝鮮の核やミサイルを「重大な脅威」と指摘したことに対し、「言語道断であり、北東アジアの危険勢力について記すなら、それは日本自身だ」と反発する論評を掲載した。朝鮮中央通信が伝えた。白書が日韓が係争中の竹島（韓国名・独島）の領有権を明記したことについても、「わが民族の自主権に対する侵害行為」と批判した。

Last February, Japanese government made protest against Korean Defence Paper, in which Korea wrote that Japan's Takeshima as Korean territory.

Japan makes a protest stealthily
Korea wrote that Japan's Takeshima as Korean territory in their "National Defence White Paper 2008 version" using a photo of Takeshima as its cover. Japanese government made a protest to Korean government through the Japanese embassy in Seoul and summoned the men in charge from the Korean embassy in Tokyo to make a protest. The protest was made on the 23rd when the white paper was published. However, Japanese government did not announce it officially so that it was not known to foreign people including Korean people at all.

Korean government firmly denies Takeshima/Liancourt Rocks is territorial issue, but as far as we know, it is the Territorial Dispute, indeed. Korean government should agree to bring this territorial issue to ICJ and settle bilateral problem peacefully.
