Grass Labyrinth (草迷宮, Kusa meikyū) is a Japanese film directed by Shūji Terayama which was released in France in 1979 and in Japan in 1983.
A surreal excursion into a young man's subconscious as he searches for the words to a tune that his mother may have sung to him as a child.
The dreamlike images culminate in a scene of a girl's naked body covered with calligraphic characters.
[1] Grass Labyrinth was originally one of the installments in a French movie package called Private Collections, the other two sections being directed by Walerian Borowczyk and Just Jaeckin, both associated with avant-garde films with strong sexual content.
Grass Labyrinth was the longest of the three and was later (1983) released as a separate film in Japan.
