Cultural festivals (文化祭 bunkasai?) in Japan are annual open day events held by most schools, from nursery schools to universities at which their students display their artistic achievements. People who want to enter the school themselves or who are interested in the school may come to see what the schoolwork and atmosphere are like. Parents may also want to see what kind of work their children have been doing. The festivals are usually open to the public, especially at high schools and universities.
According to the curriculum guidelines of the Ministry of Education, cultural festivals are part of special activities and are defined as "events which aim to use the results of everyday learning to heighten motivation".
The cultural festivals are parts of regular lessons in elementary schools, junior high schools, and high schools, so the students are obligated to attend for graduation. In universities, the cultural festivals are placed as extracurricular activity, so attendance is not required.
Traditionally, most schools hold festivals on or around Culture Day (November 3), a Japanese national holiday. Normally it is held on a Saturday or Sunday sometimes even both.
"Cultural festival" (bunkasai) and "university festival" (daigaku-sai) are common nouns in Japanese, so particular names of cultural festivals depend on each school. For example, the festival at the University of Tokyo, Komaba Campus is named Komaba-sai.
The school festivals of junior high schools and high schools may also sometimes be called gakuensai (学園祭?), gakuinsai (学院祭?), or gakkōsai (学校祭?).
