The humble blackboard is serving as the canvas, and colorful chalk the paint, for young Japanese artists.
“Kokuban Art Koshien " is an annual national chalk art championship for high school students. Combining the word for “blackboard” ("kokuban") and the famous stadium where high school baseball is contested, the contest attracts artworks, all drawn on blackboards, usually over summer break, from about 300 high schools and junior high schools.
