A questionnaire was designed to inquire the actual conditions of dietary life on the first 3 days of New Years 1986-1992. The data on 1986, 1989 and 1992 were picked out and analyzed by time series analysis in a two-way layout. Four hundred and forty questionnaires of female college students returned 3 years in total. The findings were summarized as follows : 1) The distribution of the numbers of taken dishes from time to time was shifted from 2 peaks to 3 peaks a day as shown by smoothing line. 2) There were no significant differences between yearly variances of staple diets, side dishes and "Shirumono" (a kind of soup) respectively, but significant differences between daily variances of these. Besides these, there were significant differences between yearly variances of drinks and others. 3) There were significant differences between daily variances of "Zoni," "Osechi," and "Toso" respectively. These typical traditional diets were obviously taken more on the first day than the second or third day of New Year. 4) The ratio of dining out of staple diets shifted increasingly year by year and day by day, and the numbers dining out were significantly different between yearly variances and daily variances. 5) The Japanese style dishes of dining in was on the decrease, besides another style dishes was on the increase from first day to third day.
