69 (シクスティナイン, Shikusutinain) is a roman à clef novel by Ryu Murakami. It was published first in 1987. It takes place in 1969, and tells the story of some high school students coming of age in an obscure Japanese city who try to mimic the counter-culture movements taking place in Tokyo and other parts of the world.
Synopsis
Thirty-two-year-old narrator Kensuke Yazaki takes a nostalgic look back at the year 1969, when he was an ambitious and enthusiastic seventeen-year-old, living in Sasebo, in Nagasaki, where he gets into antics with his equally ambitious and enthusiastic best friends, Iwase and Adama.
Their priorities are girls, cinema, music, literature, pop culture, organizing a school festival to be called "The Morning Erection Festival", besting teachers and enemies, and finding a way to change the world somehow.
