Social and family ties in Japanese traditional communities have declined, evidence of which is the widespread isolation from the community and often lonely deaths. This research aims to find a way to solve this problem. Here, we propose a new value system to revive Japanese communities by focusing on pioneering practices to create a new type of community in the Islamic world. The history of the Islamic world provides economic and social wisdom in accordance with the teaching of Islam, including promoting commerce and fair trade, as well as charity and support for the impoverished and socially vulnerable. The contemporary Islamic revival challenges market fundamentalism, and proposes a new economic and social philosophy with reconstructing and renovating abovementioned ideals. This study will include field research of Islamic mutual-support funds and Islamic finance in Indonesia, Malaysia, and the Middle East. We will then clarify the Islamic principle of coexistence, the economic philosophy embedded in society to alleviate poverty and revive communities. The outcome of the research is expected to contribute to several grass roots activities initiated within Japanese civil society via civil dialogues between the Islamic world and Japan.
