'The things happening on Tokyo's streets are always fascinating to me," Nobuyoshi Araki told me during an interview in 2012. Though best known for being the maestro of Japanese erotica, Araki has retained a particular love for street photography. Now 75, he still loves to prowl around the streets of Shinjuku and Ikebukuro with his old camera. And he is not alone — many renowned Japanese photographers have launched their careers from the streets of the metropolis. Ihei Kimura was one of the first photographers to stand on the thronging streets of Ginza in the early 1950s, and snap away at the shoppers, those intent on embracing Western culture, ideas and fashion after the dark years of war and defeat. Kimura treated the streets like a studio, and generations of photographers followed his example. As with Araki, they are drawn to the ever-changing cityscape and its constant metamorphoses. What's here today could be gone tomorrow, and magazines such as "Tokyojin" are devoted itself to documenting and archiving the here-and-now of Tokyo streets in their brief and strange glory.
