This paper explores the legacy, current developments, and future impact of simulation and gaming in Japan, with a focus on the Japan Association of Simulation and Gaming (JASAG). Drawing on the outcomes of the ISAGA (International Simulation and Gaming Association) conferences hosted in Japan (1991, 2003, 2015), the study highlights how Japanese researchers have integrated simulation and gaming into education, policy-making, disaster preparedness, organizational development, and community engagement. The analysis emphasizes Japan’s unique commitment to ethical considerations, social responsibility, and participatory design. Japanese scholars have developed culturally sensitive simulations to address complex societal issues, combining technological innovations with traditional methodologies. JASAG has played a pivotal role in institutionalizing gaming simulation as a scientific discipline and a transformative tool for societal improvement. The paper underscores the interdisciplinary nature of the field and outlines Japan’s contributions to advancing theory, practice, and global dialogue in simulation and gaming research.
