Chikio Hayashi had paid his abiding respect to Kinji Mizuno with whom he had been endeavoring for over fourty years to elucidate mechanisms of complicated human behaviors by means of statistical methods. Investigation of research activities of Mizuno leads to the clarification of Science of Data by Hayashi as well as to further development of behaviormetrics. Contributions of Mizuno to behaviormetrics, however, has not sufficiently been known. His efforts are presented to survey researches including the Japanese national character by statistical surveys, disaster preparedness education for school children and other studies of human behaviors. The appreciations to Mizuno by Hayashi himself are also shown, which were addressed at the Memorial Party of late Professor Kinji Mizuno in 2000.
