We evaluated the effect of Shokuiku (Japanese style food education) intervention program, unifying the lecture on the soul and history of traditional cuisine 'Seigakumochi' of Chiba-prefecture, and school lunch using it for 4th to 6th-grade primar y school children. We used a 7-points scale with face icon to easily understand for children. Pre-questionnaire was performed on the day of school lunch using 'Seigakumochi' before a month of the intervention. After the intervention program, the same questionnaire was per formed to compare to the pre-questionnaire. The scores between pre-and post-intervention were compared using a nonparametric Wilcoxon signed-rank test. The scores after the Shokuiku-intervention categorized in "traditional food culture" as well as an "importance of diet" and a "mental and physical health" were significantly increased (p < 0.05) . We divided into three groups by the ascending order of total score of interest for 'Seigaku-mochi' at pre-questionaries and exploratory analysis was performed. Our results indicated 7-points scale with face icon can be applied to evaluate other types of Shokuiku-intervention programs.
