Since few Japanese universities have courses in musicology or theater studies, the program of this field of study is all the more unique. Students of musicology study a wide variety of genres, including Western classical music, ethnic music, Japanese classical music and popular music. Students of theatre studies learn a wide variety of performing arts, including European classical and modern plays, Japanese traditional and contemporary plays, musicals and ballets. In addition to the histories of music and theatre, students study the relations of music and theatre with other disciplines, including anthropology, sociology, aesthetics and literature.
