The school badge was designed by a student in 1948 when the school was restructured as Miyazaki Prefectural Miyazaki Omiya High School. It consists of bamboo leaves, a hexagon shaped snow crystal with the character 髙, meaning "high school," and lights. The image of bamboo symbolizes the growth of young students and was inspired by local poet Bokusui Wakayama. The snow crystal represents hard work, which comes from a Chinese legend. The lights are a symbol of the shining liberal spirit of our school.
