Japan is fundamentally reshaping its military and intelligence infrastructure to take on greater security responsibilities in the Indo-Pacific, including centralising intelligence coordination and expanding defense cooperation with regional partners. These changes aim to reduce U.S.-Japan alliance asymmetry by increasing Japan's military role and defense spending, affecting regional security dynamics.
