The Life archives are an easy thing to get lost in, dishing up one historical gem after another. In particular I loved the 1964's photographs of Japanese youth, captured by Michael Rougier.
"Nowhere in the world does youth seem to dominate a nation as they do in Japan. They are overwhelming and everywhere, surging, searching, experimenting, ambitious at some times, helpless and without hope at others. Isolated on a tight little island, they have not, except on the surface, become international like their counterparts in freewheeling Europe."
