愛のコリーダ
The title of the song was taken from the French-Japanese film "In the Realm of the Senses", originally titled "Ai no Korīda" (愛のコリーダ), which means "Bullfight of Love" in Japanese. The erotic art film, directed by Nagisa Oshima, was a fictionalized and sexually explicit treatment of an incident from 1930s Japan. It generated great controversy during its original release; it was intended for mainstream wide release, but it contained scenes of unsimulated sexual activity between the actors.
