Abstract: Humanitarian assistance is one of the most important criteria for evaluating the effectiveness of foreign policy of a state. The provision of humanitarian aid is currently a key area of Japan's international activities and foreign policy. As one of the world's largest humanitarian aid donors and the oldest member of the OECD's Development Assistance Committee, Japan provides assistance in practically all areas of the world's conflicts and natural and anthropogenic hazards. Official Development Assistance (ODA) and humanitarian aid as its subspecies are considered as a practical tool for Japan's international humanitarian activities. Japan's experience in the field of humanitarian assistance is the object of research by both Japanese and foreign authors who evaluate Japanese humanitarian assistance in different ways. A distinctive feature of modern Japan's humanitarian assistance is an integrated approach to providing aid, with an emphasis on cooperation with international organizations and the attraction of available funds from various government departments and organizations. Japan plays a leading role in the field of humanitarian assistance in the international arena and takes an active part in shaping the international agenda in this area.
