LIFE.com has a beautiful gallery of Michael Rougier photographs from Japan in 1964: runaways, rock and rollers, biker gangs, “pill kids” and other Japanese teens. LIFE Magazine published some of these in September, 1964, but some have never before been published.
Above, the original caption from 1964: “Kako, languid from sleeping pills she takes, is lost in a world of her own in a jazz shop in Tokyo.”
