What are Japan’s “national interests”? Let us define them as the: preservation of the Japanese territories; protection of the lives and property of the Japanese people; prosperity of the Japanese economy, businesses, and people; and dignified preservation of Japanese values, culture and historical perspective; as well as the acquisition and retention of the kind of influence and voice that are needed in the international arena to secure the aforementioned interests for the nation. Having redefined “national interests,” we need to enhance the national power that supports foreign policies and actively practice diplomacy that contributes to the world.
