A fixed-alternative questionnaire method and daily pedometer steps survey was conducted to 1,346 Japanese children from Yamagata, Saitama, Chiba, Tokyo, Kyoto, Fukui, Hyogo, Ehime, and Okinawa Prefectures. Omron Health Care HJ-151-K pedometer was used throughout this fieldwork. Descriptive statistics for pedometer data indicated significant difference between weekdays and weekends. Whereas averages of weekday steps were ranged form 10,000 to 13,000, standard deviations were ranged from 4,000 to 6,000, mean weekend steps were approximately 8,000±4,500. Aging effect and gender difference for daily pedometer steps were recognized. While boys' average steps were 9,683 for preschool children, 13,748 for Grade1-2, 14,145 for Grade3-4, and 11,681 for Grade5-6, girls' averages were 8,837 for preschool children, 11,624 for Grade1-2, 10,575 for Grade3-4, and 9,864 for Grade5-6. However children who participate in organized sports activity accumulate about 1,500 more daily steps that those children who do not participate in these types, this critical effect of organized sports participation was not clarified by controlling grade and sex.
