Roppongi 六本木 is a section of Tokyo's Minato ward infamous for its nightlife, much of which is geared squarely at foreigners. But Roppongi has recently become respectable again even among the Japanese thanks to the opening of Roppongi Hills, a massive shopping and dining complex.
The area around Roppongi to the south and west is known as Azabu 麻布. These districts are generally quieter than Roppongi but have also absorbed some of its vibrant commercial activity and nightlife.
