It is desirable for children in kindergartens and nursery schools to have sufficient time for play, and it should be noted that whether play time is replete or not is deeply related to the children's satisfaction i.e., the repletion of their inner feelings, and that the school activities are in fact ruled by the daily work schedule. A questionnaire survey involving child-care persons was conducted in 1987 with regard to the relation between "flow of play" and "daily work schedule." Again in 2007 the same survey was conducted to study what change had taken place in the twenty years. There was no difference between the two survey results as to the basic principle governing the length of play time. About 90 percent of the child-care persons answered in both surveys that play was basically controlled by the daily work schedule but the play time might be changed depending on children's eagerness. To the question "Do you find mismatched timing between the children's flow of play and the daily work schedule as well as hesitation to go to the next activity?," 70-80 percent of the answers were "Positive from time to time" though the number of the answers "Frequently positive" was higher in the 1987 survey. "We wait until the children's eagerness for play shows signs of being abating" was found at a relatively highrate in the 1987 survey.
