Sakuran

From Fifay.net: A poor peasant girl was sold to a brothel in Edo. Her new life started from the day when she had her first full-bowl of rice. After many struggles, she became a cultivated Oiran. While her beauty never failed, her hope for freedom faded with the passing seasons. Yoshiwara of Edo was a man's heaven, but a woman's hell: all was sakuran.
