The OECD’s Development Assistance Committee (DAC) conducts reviews of the individual development co‑operation efforts of DAC members once every five to six years. DAC peer reviews critically examine the overall performance of a given member, not just that of its development co‑operation agency, covering its policy, programmes and systems. They take an integrated, system‑wide perspective on the development co‑operation activities of the member under review and its approach to fragility, crisis and humanitarian assistance.

Japan combines diplomatic, peace and development efforts to achieve sustainable development and implements the Sustainable Development Goals (SDGs) through a whole-of-society approach. It values self-reliant development, country ownership and the mutual benefits of development co-operation for Japan and its partner countries. Japan is recognised as a global champion of disaster risk reduction. Increasing official development assistance could strengthen Japan's leadership and commitment to the SDGs and a mechanism would help ensure coherence between domestic policies and global sustainable development objectives. Whole-of-government country policies would ensure synergies across Japan's portfolio and it could be more explicit about how programmes reduce poverty. More streamlined systems and procedures would make Japan a more agile donor.
