Nishi Shinjuku (西新宿) is a district west of Shinjuku Station in Tokyo, Japan. The district, best known for its wide array of skyscrapers is a major Tokyo business district that first started to truly develop in the mid 1970s with the Keio Plaza Inter-Continental. The most recent building to be completed is the Tokyo Metropolitan Government Building and for a long period of time, Tower I, located here, was the largest building in Japan. Nishi-shinjuku has grown greatly since the 1970s and continues to spread west, away from the city center. The Nishi-Shinjuku 3-Chome Redevelopment project is underway as well, which will lead to three of the four tallest buildings of Japan being added to the area.
