Abstract
For the past 30 years, together with the Chemical Software Society of Japan and the Society of Computer Chemistry, Japan, we have conducted scientific activities related to the interdisciplinary aspects of chemistry and computers at the Chemistry PC Workshop. From the early development of computers to their widespread use in all fields, we have witnessed the 2,300,000-fold improvement of computer performance. We are managing our Society at a time when such activities are greatly needed. We explained our footprints until now at the 10th anniversary symposium.
