Adapted from a sex-stuffed cult novel, LALAPIPO (a play on the phrase “A Lot of People”) follows divergent seedy strands of sexual and narrative spaghetti through the sticky Tokyo night. There’s a chubby freelance writer who’s so obsessed with masturbating to the sound of his upstairs neighbors going at it that he forgets to deal with his own love life and when he finally does have sex he is immediately filled with self-loathing. The upstairs neighbor’s story then splits off like an amoeba: she’s an office lady seduced by a “talent scout” who is falling down the sex industry ladder, moving from hostess, to massage girl, to private karaoke attendant. The talent scout’s story then splits off and runs in its own direction, revealing the sorry state of this young pimp’s soul. From there, the movie takes more and more time to consider the lives of more and more characters until the entire Japanese sex industry is filled with the wailing of lost souls.
