Japan's Contribution to UN Peacekeeping Operations (PKO)

February 27, 2024

1. Overview

In order to play a more proactive role in fostering international peace, Japan enacted the Act on Cooperation with United Nations Peacekeeping Operations and Other Operations (the International Peace Cooperation Act) in June 1992. Since then, Japan has made substantial personnel and in-kind contributions for efforts toward international peace mainly led by the United Nations.
The Act establishes the four pillars of Japan’s international peace cooperation: United Nations Peacekeeping Operations, Internationally coordinated Operations for Peace and Security, International Humanitarian Relief Operations, and International Election Observation Operations. It also provides a system for Japan’s contribution to these operations through dispatching personnel and Self-Defense Forces (SDF) contingent and in-kind contribution to provide necessary supplies.

2. Purpose of the Act

To establish the domestic framework for extending appropriate and prompt cooperation with UN Peacekeeping Operations, Internationally coordinated Operations for Peace and Security, International Humanitarian Relief Operations and International Election Observation Operations, and thereby enable active contribution by Japan to international peace efforts centering upon the United Nations (Article 1).

3. The Five Principles for Participation in Peacekeeping Troops

The following principles have been arranged to ensure that participation in Peacekeeping Operations is in accordance with Article 9 of the Constitution of Japan.

  • (1) Agreement on a cease-fire shall have been reached among the parties to armed conflicts.

  • (3) The operations shall strictly maintain impartiality, not favoring any of the parties to armed conflicts.
  • (4) Should any of the requirements in the above-mentioned principles cease to be satisfied, contingent dispatched by the Government of Japan may terminate International Peace Cooperation Assignments.
  • (5) The use of weapons shall be limited to the minimum necessary to protect the lives of personnel, etc. When the consent for acceptance is deemed to be consistently maintained, the use of weapons in defense of the mission mandate is allowed in accordance with specific requirements.

5. Japan’s Specific Cooperation Achievements

(1) Cooperation in the United Nations Peacekeeping Operations

Since the enactment of the Act, Japan has deployed personnel to a total of 13 United Nations Peacekeeping Operations (as of January 2024, SDF personnel are currently deployed as staff officers to the United Nations Mission in the Republic of South Sudan (UNMISS)). So far, the SDF has been deployed to Cambodia, Mozambique, the Golan Heights, Timor-Leste, Nepal, Sudan, Haiti, and South Sudan, and the police to Cambodia and Timor-Leste.

(2) Cooperation in Internationally coordinated Operations for Peace and Security

Since April 2019, Japan has deployed SDF personnel as staff officers to the Multinational Force and Observers (MFO) operating in the Sinai Peninsula, Egypt.

(3) Cooperation in International Humanitarian Relief Operations

Japan has deployed personnel to six International Humanitarian Relief Operations. Japan deployed SDF units to Rwanda to provide medical care to Rwandan refugees, and transported humanitarian relief supplies by SDF aircraft to refugees in Timor-Leste, Afghanistan and Iraq, and conflict-afflicted people in Iraq and Ukraine.

(4) Cooperation in International Election Observation Operations

In June 1998, Japan amended the Act to further improve the system for deploying Japanese personnel. Since the amendment, Japan has deployed personnel to Bosnia and Herzegovina (twice), Timor-Leste (three times), Kosovo, Democratic Republic of Congo, Nepal, and Sudan, in total of nine international election observation missions (before the amendment, Japan deployed personnel to Angola, Cambodia, Mozambique and El Salvador, in total of four missions).

(5) Contributions in Kind

Japan has made in-kind contributions to UN Peacekeeping Operations, the United Nations High Commissioner for Refugees (UNHCR), the International Organization for Migration (IOM) and the Intergovernmental Development Organization (IGAD) in total of 30 times.

(6) Public Opinion Survey

According to the "Public Opinion Survey on Diplomacy" conducted by the Cabinet Office in September 2023, about 90% of respondents support Japan's participation in UN Peacekeeping Operations at the current level or more actively than before. This is considered to reflect the public's evaluation of Japan's past cooperation with Peacekeeping Operations. The Government of Japan will continue its efforts to publicize Peacekeeping Operations in general and Japan's participation in particular, so that public understanding and support for such cooperation will be further deepened.
