Abstract: Japans involvement in the South China Sea has a long history, especially since 2010. With the growth of Chinas naval and maritime capabilities, the Japanese governments policy of interfering in South China Sea affairs has begun to appear. In particular, under the guidance of the new version of the “Japan Security Strategy”, the Kishida government, as a country highly dependent on imported energy and foreign trade, in order to prevent a rising China from relying on its own strength and cut off its energy and trade routes in the South China Sea, Japan did not hesitate to design a new OSA system of free military aid to foreign countries, increase the supply of military equipment to South China Sea countries, liaise with South China Sea countries, and strengthen cooperation against China in the South China Sea. It can be said that Fumio Kishidas South China Sea policy is not an isolation policy, but a link and part of Japans foreign strategy, Japans overall maritime strategy, and Japans Indo-Pacific strategy. Although the Kishida governments South China Sea strategy claims to be an international maritime order based on universal values and ensure freedom of navigation and aviation in the South China Sea and other areas, the result not only fails to promote stability and peace in the South China Sea region, but also increases instability and confrontational factors in the region.

Key words: the Kishida government, South China Sea Strategy, “Indo-Pacific Strategy”, joint military exercises, military assistance, Official Security Assistance(OSA)
