CSR Activities

In addition to serving as director of Japan’s largest e-learning group organization “e-Learning Consortium Japan” and running Japan’s only comprehensive e-learning forum “e-Learning Award Forum”, we participate in various other social contribution initiatives to further the development of e-learning, such as the e-Learning Association, ICT Education Promotion Council of Japan and The University CIO Forum. Moreover, capitalizing on our more than 15 years of experience in e-learning and with the aim of contributing to society, we established the e-Learning Strategy Research Institute in April 2007, which conducts studies and research into e-learning technologies, market and educational effects. In addition, we are simultaneously engaged in support activities targeting people studying IT technology at vocational training schools with the goal of re-employment in web-based industries.
