At the centenary of Japan's Annexation of the Korean Empire in August 2010, speculation centered on whether Japan could achieve a radical departure from its traditional foreign policy of ‘Datsu-A Nyu-Ou’, namely leaving Asia to become a Western style country. This policy, resulted in Japan's colonization of Korea in August 1910 and led further to the invasion of China and other Asian nations, ending in Japan's utter defeat in August 1945.

This article suggests that many post-war violations of international human rights law by Japan may have their roots in pre-war violations of international law.

7 For example, it is increasingly difficult to find references in textbooks to the so-called ‘comfort women’. I first learned about this issue when Senator Motooka Shoji raised the question of the ‘comfort women’ in 1990. In February 1992, I brought the issue before the UN Commission on Human Rights.UN Doc. E/CN.4/1992/SR.30/Add1, para. 14-18. The UN summarized the author's oral statement as follows: “… One example was the situation of Korean girls and women abducted by Japanese forces during the Second World War for use as sex slaves. … In January 1992 the Government of Japan made an apology to the Korean People but offered no compensation or other effective remedy to the victims as required by article 8 of the Universal Declaration of Human Rights.…”
8 The brief calligraphy pieces in Chinese were made by Ahn Jung-geun, who wished to convey deep philosophical messages to the Japanese, while waiting for execution in prison. Ryukoku University was reluctant to make them public, fearing attack by rightists. To treat Ahn Jung-geun respectfully might reverse the understanding of the standard history recognition in Japan, as Ahn had been recognized as one of major criminals in Japan, while he was considered to be one of the most symbolic heroes, who sacrificed his life to recover independence in Korea.

31 The author's major field is international human rights law (practices), not treaty law. (2) Prof. Sasagawa is a specialist on the constitution. In a joint study (Sasagawa Norikatsu and Yi Tae-jin, eds., International Joint Study: Annexation of Korea and Reexamination under Modern History and International Laws, Akashi Shoten, 2008, he presented in-depth research supporting the descriptions in the 1963 ILC report on the invalidity of a treaty forced on national delegates.

His specialty is international relations.

36 Article 13 of the Constitution of the Empire of Japan provides that ‘the Emperor shall declare wars, pursue reconciliations, and conclude all types of treaties’, thereby granting the Emperor the authority to sign treaties. Japanese domestic law established procedures to sign treaties. Prof. Unno cited evidence written in 1936, but he failed to examine the Japanese Foreign Ministry's practices in 1905.

The author also cited an exception: ‘when an international contract is personally conducted by a sovereign or other person exercising the sole treaty-making power in a state, or when it is made in virtue of the power incidental to an official station’. The 1905 ‘Korea Protectorate Treaty’ was not signed by Emperor Kojong. No organization existed with authority equal to that of Emperor Kojong.
