The Tokyo International Conference on African Development（TICAD）acts as an important diplomatic instrument for Japan. As a global mechanism for Africa’s development，TICAD has played an active role in promoting high-level political dialogue among African leaders and partners and seeking support for Africa’s development. The 7th TICAD（TICAD VII）adopted Yokohama declaration 2019 and Yokohama action plan 2019，setting the tone for Japan’s African policy in the coming three years or even longer time. In order to coordinate with the strategic adjustment of the United States and promote the goal of becoming a political power under the framework of Indo-Pacific strategy（vision），Japanese government has made major policy adjustments in accordance with the international changes and the domestic political and economic situation，so as to realize the transformation from the government-led mode to the government-business joint mode of cooperation and from unilateral economic assistance to strategic cooperation. It shows Japan’s intention of strengthening its interests in Africa，catering to the strategic adjustment of the United States and containing China’s influence. Japan’s adjustment of its policy towards Africa is based on the context of Japan’s considering China as its main competitor，and puts forward new issues on China’s handling of its diplomacy towards Africa.
