The story is based on a famous murder case that happened in late 1930s Japan. A geisha strangled a rich man and cut off his private parts after making love with each other in a room for a month.
Learnt from the Q&A session that this film belonged to the "Roman Porno" genre created by Nikkatsu in the 60s to save them from bankruptcy. The obsessive love between the couple was portrayed realistically and the flashbacks on the geisha's past made me understand her better. Thought a good companion film could be "World of Geisha" shown in cinemas a few months ago that starred the same leading actress. Looking forward to catch "In the Realm of the Senses" by Nagisa Oshima based on the same true story if it is ever allowed to show here.
