First time when I visited this place, I liked Tochō (officially called Tokyo Metropolitan Main Building No.1) so much, that I forgot to take pictures with other buildings...
I took this photo in front of the Tochō skyscraper, with the eight-story Tokyo Metropolitan Assembly Building. In the back you can see other interesting Shinjuku skyscrapers, like Keio Plaza (center), Mitsui Building (left, 8th place in the Top 10 Tokyo Skyscrapers) or Shinjuku Center Building (the brown building in the back, 9th place in the top).
