Roppongi Hills in Tokyo is often mentioned as one of the largest and most successful urban renewal projects ever carried out after World War II in Japan. The project began in 1984 and lasted approximately 17 years. The plan involved the city government, real estate developer Mori Building Co. and residents living in the construction zone. Just to reach agreements with 500 rights holders, the company took more than 15 years (“Roppongi Hills”). The concept of the Revival Plan seems completely opposite to that of Jane Jacobs, but there is a moment in the history of this Roppongi Revival Plan that is equivalent to her philosophy. Jane Jacobs' idea of ​​a local community in the city was accidentally realized during the construction process of the Roppongi Hills half a century later in Japan. The Roppongi Hills is one of the largest and most magnificent mega-resorts in Japan. They include offices, apartments, shops, restaurants, cafes, cinemas, a museum, a hotel, a large television studio, an outdoor amphitheater and several parks. They are located in Roppongi District of Minato Ward and cover 11.6 hectares in area. Around 20,000 people work in offices, restaurants and stores and 2,000 people live in residential towers. On weekends, around 130,000 people visit the site (Matsutani). They feature many of the latest earthquake-resistant technologies, such as shock-absorbing walls, green mass dampers, and emergency power generator systems. They also have an autonomous cogeneration and water supply system so that they can operate on their own even in the event of a large earthquake (“Safety and Security”). 25% of the site is covered in greenery, which alleviates the heat island effect and raises the temperature in the area to 2-3 degrees C...... middle of paper ......nt redevelopment of the city of Tokyo today.Works citedBremner, Brian. “Rethinking Tokyo.” Business week.
