The bureau was founded through the National Intelligence Council Establishment Act passed in May. The NIB will be overseen by the new National Intelligence Council (NIC), headed by the prime minister and nine other cabinet-level officials. The NIC will deliberate on a new national intelligence strategy as well as additional intelligence-related legislation, including an anti-espionage law. The new strategy document would be the first in Japan, with intelligence having previously been included under the National Security Strategy, one of Japan’s primary military documents. This includes a foreign intelligence agency modeled on the US CIA slated to be established by early 2028.
