Tokyo, the largest city in the world, is often pictured as a mix of skyscrapers, neon lights, billboards, elevated expressways, multi-layered train tracks and streams of people crossing huge crossings in central areas such as Shibuya, Shinjuku or Shinagawa. Tokyo has risen like a phoenix out of its own ashes, and the city was rebuilt to become a symbol again. Tokyo was originally known as Edo, a small castle town Shogun Tokugawa Ieyasu turned into his military base and the centre of the feudal government. The Tokyo government used the occasion of the Tokyo Olympics in 1964 to set up a fund for new urban projects and infrastructures that included roads, highways and public transport systems. Some people add next to drinking and shopping alleys also alleys famous for fashion, like seen in the case of the Cat Street in Harajuku, Tokyo or the Look Street in Koenji, also because the places are recently known as subculture places.
