The task of the PSIA is to ensure public security on the basis of laws including the Subversive Activities Prevention Act and the Act on the Control of Organizations Which Committed Indiscriminate Mass Murder. Accordingly, as well as conducting surveillance of Aum Shinrikyo, the PSIA gathers and analyzes intelligence about situations at home and abroad that could affect public security, including intelligence concerning various domestic groups, international terrorism, and developments in other countries, especially neighboring states such as North Korea, China, and Russia. Through these endeavors, the PSIA is striving to contribute to policymaking via the provision of intelligence, as a member of the intelligence community in Japan.

　Recently, both at home and abroad, Japan has found itself facing a diverse array of situations, most of which are new challenges that it has not faced for many years. These have arisen against the background of numerous major changes of great significance in the context of world history, including a shift in the world economy’s center of gravity from west to east, the growth in China’s economic and military might, the proliferation of nuclear weapons and other weapons of mass destruction, and the IT revolution and the remarkable development of cyberspace.

Amid this situation, as one of the advanced democracies of East Asia, Japan is expected to maintain stability and development, while defending such universal values as freedom, democracy, basic human rights, and the rule of law, thereby contributing to peace and prosperity worldwide, especially in East Asia. The gathering and analysis of intelligence is becoming increasingly important, as the cornerstone of policies aimed at this goal.

In November 2013 , the National Security Council (NSC) Establishment Act (the Act of Partial Revision of the Establishment of the Security Council) was enacted. As a key member of the intelligence community, the PSIA is required to actively supply relevant intelligence to the NSC, so it will work in close partnership with the National Security Secretariat in the future.

In addition to continuing to engage in rigorous surveillance of Aum Shinrikyo, the PSIA will strive to further improve its intelligence gathering and analysis capabilities, and aim to strengthen the contribution that it makes via intelligence, in order to respond to the needs of the times.
