Shinjuku is an administrative and commercial centre in Tokyo. It has the busiest train station in the world, the Shinjuku station. 

Shinjuku is quite popular in Tokyo for its department stores as well as its interesting array of nightlife.  The Golden Gai is known for its small shanty-style bars and clubs which are famous hang-out spots of artists, musicians, actors and directors. 

The ward is also known for its special neighbourhoods. Kabukicho is a well-known red light district in the city where prostitutes, brothels and other forms of sexual commerce can be found. The district also has a wide selection of bars and restaurants.

Shinjuku ni-chome is Tokyo's most famous gay district whereas Okubo has a high concentration of Korean residents.

The largest skyscraper district in Tokyo is in Shinjuku, in the Nishi-Shinjuku district. Shinjuku Garden is one of the most impressive and largest parks in the city. 

Waseda hosts one of Japan's most prestigious universities, Waseda University. It is near a famous commercial-residential district frequented by students, Takadanobaba.

With Shinjuku's diverse characteristics, it does not come as a surprise that the ward hosts the largest number of foreign expatriates in the country. Yotsuya and Iidabashi are highly desirable residential areas here, and are favourites among European expatriates. These two neighbourhoods are upscale, although generally quiet compared to the bustling nearby districts.

Tokyo-Tocho and Ichigaya

Tokyo-Tocho ward is surrounded by high-rise buildings and luxurious hotels.

Ichigaya is a more favoured residential choice among expatriates, and has a French community. Despite its lack of attractive green areas, Ichigaya has expensive houses and high-rise apartments.
