1. ShinjukuShinjuku is Japan's largest neighborhood. It's probably the world's largest neighborhood. At least it has the world's busiest train station — over 3.5 million people a day stream through Shinjuku Station.
The West side of Shinjuku is a large business district. The East side features several entertainment districts that are popular amongst salary men such as Kabukicho and Golden Gai.
2. Tokyo Station Area (Marunouchi & Yaesu)The Tokyo Station area is surrounded by massive business districts such as Marunouchi, Yaesu and Otemachi. Any space in the area not taken by an office building is devoted to entertaining and feeding Tokyo's salary men.
3. ShimbashiShimbashi lies next to Ginza (an office lady paradise). The two neighborhoods perfectly illustrate the difference between salary man and office lady entertainment preferences. Ginza is a luxury shopping area known for fine dining and Shimbashi is known for its yakitori restaurants and laid back izakaya.
4. ShinagawaShinagawa is a sea of black suits each morning as armies of workers race for their offices in the area. Evenings are more relaxed as these same workers enjoy Shinagawa's many izakaya.
5. GotandaGotanda is stuck in the 1980s. Salary men like it nonetheless.
6. YurakuchoYurakucho looks much like Tokyo did before WWII. Its open air eateries under the railway tracks of the Yamanote train line have a charm that salary men can't resist.
7. YotsuyaYotsuya is on the western side of the Imperial Palace. It's one of Tokyo's oldest urban areas. Yotsuya is known for ghosts and ninja graves. It's also filled with izakaya and odd nightlife.
8. Akasaka MitsukeAkasaka Mitsuke is a central neighborhood sandwiched between Tokyo's largest business districts and a big area of government buildings (Nagatacho and Kasumigaseki). Akasaka Mitsuke's many restaurants and bars attract salary men from both the government and business side of the fence.
