The Center for Interdisciplinary Study of Monotheistic Religions (CISMOR), established in 2003, conducts comprehensive and interdisciplinary research and educational activities related to the monotheistic world. It fosters specialists who can help to achieve coexistence among different civilizations and at the same time makes the results of its research available to the world at large, with the goal of becoming a mediator between the Islamic, Judaic, and Christian worlds. Although, the three Abrahamic religions that originated in the Middle East–Judaism, Christianity, and Islam–are closely related as brothers, Western countries have a long history of repeated conflicts and antagonism with the Islamic world. In order to achieve peace, security, and the coexistence of civilizations in today’s world, we must undertake comprehensive and interdisciplinary educational and research activities from a civilizational perspective. CISMOR is unlike any other research institute in the world because it centralizes in-depth interdisciplinary research on all three Abrahamic religions and also because of its unique location in Japan, a country that is free of historical or cultural constraints on such studies, thus allowing the institute to take an entirely objective point of view. Research on Abrahamic religions is still a comparatively new field in Japan, and there is still a lot to be learned. By increasing our understanding of Abrahamic religions, we will at the same time contribute to a deeper understanding of Japanese religion. We try to find the way to contribute to reform the Abrahamic religions from the stand point of Japanese religiosity. More information is available at http://www.cismor.jp/.
