At his last appearance in the Peacebuilders Training Course in Hiroshima on 25 February, Professor Hasegawa engaged in a dialogue with Hiroshima peacebuilders about the need to integrate the teachings of Eastern and Western philosophical wisdoms in managing the conduct of human behaviors in society and in their relationship with the world.

　Professor Hasegawa emphasized that more attention should be paid to the importance of developing national leaders who can harmonize universal values and principles on one hand and local traditions and customs on the other. In conflict-prone and post-conflict countries, the existence of national leaders committed to national interest is of paramount importance, while institutional development based on rule of law and democratic principles is required to bring about a stable society.
