'six trees') is a district of Minato, Tokyo, Japan, famous for the affluent Roppongi Hills development area and popular night club scene.

Roppongi was not extensively populated until after the Meiji Restoration, although the area was trafficked for centuries and served as the site of the cremation of Shōgun Tokugawa Hidetada's wife in 1626.

After World War II, during which the area was again destroyed, this time by aerial bombing raids, the United States Army and Allied government officials occupied several facilities in the area, beginning Roppongi's reputation as a neighborhood with large numbers of non-Japanese.

Several large US military installations were located in the nearby area, with Hardy Barracks probably the most significant (the US Embassy Housing Compound and Akasaka Press Center including Hardy Barracks Recreational Lodging, Stars and Stripes office and heliport are still there).

Starting in the late 1960s, Roppongi became popular among Japanese people and foreigners alike for its disco scene, which attracted many of Tokyo's entertainment elites.

Recently, Roppongi has enjoyed a growing reputation for its organized events such as art festivals, dart and billiard tournaments, pub crawls,[5] robot exhibitions, beauty pageants, and so on.

Roppongi is home to many important art galleries and museums in Tokyo, serving as a center hub for culture.

Although still exerting some influence in Roppongi, in recent times they appear to have shifted much of their presence to other districts in the Tokyo area.

[20][21] In 2006, Nigerian immigrants to Japan began opening a number of bars and nightclubs in the area, following an earlier group of innovators who had been in business in Roppongi for many years.

The incidents resulted in the United States embassy in Japan warning US citizens to avoid certain bars and clubs in Roppongi.

An investigation by The Japan Times in July 2011 found that though drink spiking occurred, most of the incidents did not involve criminal activity.
