The Rome Statute creating the International Criminal Court (ICC) was adopted in 1998 by 120 countries, including Japan. Since 2002, when the Rome Statue came into force, the ICC has been a permanent and independent institution. Its establishment was a historical achievement that permanently conferred jurisdiction to punish the masterminds behind heinous crimes, including genocide, war crimes, crimes against humanity, and the crime of aggression. No one who commits these crimes will thus be able to escape the consequences.

However, the power of the ICC depends entirely on member states because it has no resources of its own to make arrests and is financed by the state parties. Therefore, it is important to study the ratification process of the Rome Statute and explore potential obstacles for states’ decision to join the ICC.

Japan acceded to the Statute fairly late. While most ICC member states had ratified it by 2003, Japanese ratification did not come until July 2007.[1] The objective of my research in Japan was to gather empirical evidence to answer the question: Why did it take almost 10 years for Japan to join an institution that it presumably supported from the beginning? Literature on Japan’s accession to the ICC has thus far focused on the legal aspects.[2] My research is aimed at contributing a political aspect to this literature by analyzing different political motivations behind the ratification process. This short article discusses some of the findings of my research in Japan.

Although I am interested in the political aspects of the ratification process, it is impossible to deny the role of the legal aspects. When countries consider joining the ICC, amendments to national laws are usually necessary. The Japanese legal system is a mix of civil and common law, with civil law characteristics, adopted from the German legal system, dominating the system.[3] Japan’s ratification of the Rome Statute required the deliberation of three main legal issues.

First, Japan had to consider whether and how to accommodate the crimes under the jurisdiction of the ICC with the national Criminal Code, which is very specific and, as such, takes time to amend. As Arai et al. point out, Japan decided not to amend the Criminal Code because almost all crimes under the ICC’s jurisdiction, with a few, rather irrelevant exceptions, are already covered by Japanese laws.[4]

As Meierhenrich and Ko elaborate, another legal issue, related to the jurisdiction of the ICC, was Article 9 of the Japanese Constitution:

“Aspiring sincerely to an international peace based on justice and order, the Japanese people forever renounce war as a sovereign right of the nation and the threat or use of force as means of settling international disputes. In order to accomplish the aim of the preceding paragraph, land, sea, and air forces, as well as other war potential, will never be maintained. The right of belligerency of the state will not be recognized.”[5]

Because of this paragraph, legislating war-related laws was initially complicated, as this would imply the hypothetical possibility of Japan engaging in war-related activities. This obstacle, however, was overcome in 2004, when the Diet adopted a package of emergency legislation that enabled Japan to ratify the 1977 Additional Protocols of the Geneva Conventions.[6]

The last important legal issue was cooperation with the ICC, which Japan resolved by adopting the ICC Cooperation Law, consisting of 65 articles.[7] Altogether, the elaborate legal review of national laws and the Rome Statute, as well as the preparation of the ICC Cooperation Law, slowed down Japan’s accession to the ICC.

Besides legal questions, according to the interviews I conducted in Japan, the US policy on the ICC also delayed ratification. While the Bill Clinton administration was not enthusiastic about the ICC, the George W. Bush administration was openly opposed, starting a global campaign against the ICC and not hesitating to voice its dismay about the institution in bilateral and multilateral forums.[8] Since the United States is Japan’s most important ally, this US policy affected Japan’s willingness to join the ICC. The US opposition against the ICC started to ease after 2005, though, when the UN Security Council referred the situation in Darfur to the ICC. Shortly thereafter, Japan started to consider ratifying the Rome Statute.[9]

Another aspect that delayed Japan’s ratification of the Rome Statute was money. Due to its high gross domestic income, Japan was slated to become the main contributor to the ICC. Article 117 of the Rome Statute, defining the assessment of the contribution, left some room for interpretation, and Japan initially calculated that its contribution to the ICC would be 28% of the total budget.

Japan wanted to apply the UN ceiling of 22% to its ICC contribution, but the European Union hesitated to accept the proposal. Eventually, the ICC Assembly of States Parties approved the 22% ceiling, and ratification began to materialize.[10]

To conclude, unlike the European countries, most of which wanted to join the ICC quickly in order to show their support for the new Court, Japan was not in a hurry to ratify the Rome Statute. Rather, Japan wanted to wait and see how the newly established ICC would develop before it joined. In general, there was not much political pressure in Japan to join the ICC, but the UN Security Council’s referral of the Darfur case to the ICC clearly had a positive influence on Japan’s decision.

The impact of the Jun’ichiro Koizumi administration on the ratification process has not yet been researched in depth, and this will be the subject of my future research. Tentatively, the delay in ratification can be explained in terms of the Japanese way of dealing with international treaties, which was described in many of the interviews I conducted.

Today, Japan is an active member of the ICC, and one of the Judges, Kuniko Ozaki, is Japanese. I hope that in the future, Japan will start to actively promote the ICC in Asia, as the region is clearly underrepresented in the organization.
