Abstract: Based on its strategic goal of being a “firstclass nation”, Japan under the Abe administration has been active in the IndoPacific geopolitics. The pursuit of Japan’s “IndoPacific” geostrategic concept is reflected not only in the strategic thinking and policy ideas of Japanese leaders, but also in Japan’s diplomatic practice. The idea of Japan’s “IndoPacific” strategy is implemented through three approaches: security, economic cooperation, cultural and peopletopeople exchanges. The essence of Japan’s IndoPacific geopolitics is to seek the status of being a “political power”, to gain economic benefits and promote the economic development of Japan, and to play against China. Predictably, with the change of the pattern of interests in IndoPacific region, the development of China’s diplomatic strategy and the irreversible rise of China, the uncertainty of the U.S. strategy and the gloomy prospect of USJapan IndoPacific strategy, Japan does not have a practical basis to play a major role in promoting the IndoPacific strategy without the United States.

Key words: Japan’s diplomacy, IndoPacific strategy, policy practice, direction and prospect
