As violent extremism and de-radicalization have become topics of increasing interest around the world, this project design tailor- made programs for support and intervention efforts for the target groups in Indonesia and Bangladesh, taking into consideration specific historical and political context in which radicalization of target group took place. In Indonesia, we design a pilot program for the rehabilitation of former prisoners at Poso in Central Sulawesi, and in Bangladesh we conduct a series of trainings for staffs in charge of de-radicalization together with counseling of former prisonors, in corporation with experts from diverse disciplines, including political science, psychology, or religious studies. Anticipating that this will become an important future issue for Japan, the project encourages dialogue between experts across the countries, including publishing Japanese experts’ article to appear in international journal, for the purpose of bringing Japan’s experience to the international discussions on violent extremism and de-radicalization.
