Redevelopment District Plan (Now integrated into the current District Plans)Rapid urban growth in Japan’s metropolitan centers led to many cases where former infrastructure facilities which had promoted and enabled the very economic growth that now surrounded them, became urban brownelds after relocating to the periphery. Given the challenge to cope with multiple large urban brownelds, the introduction of the Redevelopment Planning System in the late 1980s enabled the private sector to manage and nance projects with their expertise and capital.The law promotes project proposals from private developers and through consultation and governmental approval positions them within the necessary public planning. The act contains both monetary incentives such as subsidies and low-interest financing, as well as floor-area ratio premiums where the private developer is granted an additional floor-area allowance for the project in exchange for contributions to the public realm. The law successfully achieved benets for both parties. Urban revitalization, redevelopment and updating of public facilities and amenities created a better quality of life in Japan’s urban agglomeration and introduced new commercial and housing areas to further boost the area’s attractiveness. Private developers beneted from the incentives and through the quality delivered as well as through being embedded into the municipal city planning process and experiencing property value growth.PPP & Transit-Oriented DevelopmentWhile the initial legislative and planning changes paved the way for PPP style delivery of development and emphasized shared incentives, promoting a high level of cooperation between public and private interests with clearly defined roles and authorities and transparent guideline s for qualitative and quantitative requirements which greatly helped remove the element of discretion and potential for corruption, making the process attractive to all parties, undoubtedly the flourishing development of public-private-partnership projects in Japan can predominantly attributed to one specific factor, which is Japan’s long tradition in promoting rail and transit-oriented developments along rail-corridors. Dealing with the rapid growth of economy and population after WW2 with limited land resources, urban expansion was strategically channeled along rail corridors. The existence of private rail companies in the Japanese market was also highly benecial, as these private rail companies were able to propose extension plans along their corridors with the security of future fare revenues and raising land values along the track. Promoting private rail operations and sustainable growth strategies simultaneously has developed into a successful business model within the PPP realm.Toyosu Districts 2 and 3 redevelopment Waterfront redevelopment of approximately 50 ha located 5 km from the center of Tokyo on the site of a former shipbuilding yard. Taking advantage of the proximity of the waterfront and the city center, a new waterfront lifestyle was created including industrial, commercial and residential functions. Shiodome District redevelopmentA large-scale redevelopment of an approximately 30 ha site focused on a former freight yard site adjacent to Shinbashi Station in the center of Tokyo. Urban infrastructure was prepared according to the Land Rezoning Project to form eleven super blocks and create a new CBD area. Once completed the working population is estimated at 61,000 people with 6,000 residents. Akasaka 9-Chome District Redevelopment Plan The development of Tokyo Midtown was launched in 2000 with the relocation of the Defense Agency head office. As part of the ‘urban revitalization of Tokyo’ program, the Akasaka 9-Chome District Redevelopment Plan gave way to the development an urban complex of offices, residential quarters, conference facilities and cultural/hospitality facilities; totaling at 564,000 sqm gross floor area.The World Bank denes Public-Private-Partnerships broadly as “A long-term contract between a private party and a government entity, for providing a public asset or service, in which the private party bears signicant risk and management responsibility, and remuneration is linked to performance.”Realized Projects under the Redevelopment District Plan
