Taking Responsibility for the "Once In a Century" Shibuya Great Renovation <Part 1>

The large-scale redevelopment of the area around Shibuya station is said to be a "once in a century" event, not because many skyscrapers will be built. It is because it is an attempt to reinvent the area into a completely new town through cooperation between the public and private sectors, moving the station, changing the flow of the river, and creating a new pedestrian network. Moreover, it is unprecedented in that it will be realized while maintaining the functions of a huge terminal. PACIFIC CONSULTANTS has been involved in this project since the early planning stages and continues to support it up to day. We talked to five people who have been central persons in the project for many years: Ryuji KOWAKI, Hisashi KUBO, Takayasu NIWA, Yoshio NAMIKI, and Terue KAMINO.

What is a Final Landfill Site?

Although final landfill site of industrial wastes is an important facility that supports local economic activities, its construction entails great difficulties, including the formation of consensus with local residents. It is difficult for private business sectors to construct a facility by itself, and public-involvement type construction is attracting attention. We interviewed Ko SUGIURA, General Manager of Regional Environment Business Promotion Sec., Resource Circulation Management Dept. and Toshihiko TOKITA, Technical Manager of the same section, who have a great deal of experiences in PACIFIC CONSULTANTS' construction of final landfill sites, about points to keep in mind in public-involved constructio of fifinal landfill site, and points of maintenance and operation, including business support using PFI, a typical method of PPP.

Hokuriku Shinkansen Tsuruga Extension Project Vol.3 ~ Kakehashigawa Bridge ~

The Kakehashi River is a first-class river that originates at Suzugatake in Komatsu City, flows north through the mountains, enters the plains, then changes direction to the west before flowing into the Sea of Japan. The downstream area is surrounded by the Komatsu city area, making it a valuable open space and a place of relaxation for local residents, who go for walks, fishing, boating, etc. It is also in this downstream section that the Hokuriku Shinkansen crosses the Kakehashi River just before Komatsu Station, and because the river is wide, bridge piers must be built across the river channel. As well as flood control, it became more important than anything to reach an agreement with the river manager, who is promoting the development and conservation of the river environment that is loved by local residents.

Integrated Development Project of SAGA Sunrise Park + Eiko Bridge + Saga City Cultural Center - West Square

The National Athletic Meet, which has long been affectionately known as the KOKUTAI (National Sports), will be renamed the "National Sports Festival" and the first tournament will be held in Saga in October 2024. The shift from "physical education to sports" was also reflected in the concept of venue development, and the venue was required to be used as a base for everyday sports and health that would be popular in the local area for a long time even after the tournament ended. To achieve this, a total design that looks to the future is essential, without being bound by distinctions between prefecture and city, architecture and civil engineering, or hardware and software. Ryuji KAMIDE of the Urban Design Sec. of the Osaka Social Innovation Dept., who was in charge of the exterior design of SAGA Sunrise Park and the Cultural Center-West Square, and Shuichi NONAKA of the Structure Sec. of the Kyushu Transportation Infrastructure Dept., who was mainly responsible for the design of Eiko Bridge, looked back on the initiative.

What is Public-Private Partnership (PPP)?

As it becomes more difficult to maintain public facilities and services due to financial constraints and a decline in local government employees, the government is strongly supporting the promotion of public-private partnership (PPP) initiatives as a means to solve social issues and drive a growth-oriented economy. We spoke with Takayuki Ishikawa, head of PPP Management Dept., and Tsuyoshi Yamaguchi, General Manager of the Infrastructure PPP Office in the same department, about the benefits of PPP and the key to its success.

Sanjo City's Comprehensive Private Sector Outsourcing Project

Sanjo City, which has been actively promoting comprehensive private sector outsourcing for infrastructure maintenance and management, began Phase III (5-year) of outsourcing in the spring of 2024. PACIFIC CONSULTANTS has been participating as a member of the joint venture (JV) that will receive comprehensive outsourcing since Phase II (April 2019 - March 2024), which precedes this. This is the first time for a construction consultant in the country to do so. Why did the local construction companies join a mainly made up JV, and what kind of results produced? Nobutaka INAMITSU, General Manager of the Spatial Creation Sect. of Infrastructure Management Dept., Transportation Infrastructure Div. who is at the center of the initiative, along with Ryo NAKAI and Masahiro MATSUOKA from the same section, explain the story.

Hokuriku Shinkansen Tsuruga Extension Project Vol.2 ~Miyama Tunnel~

The Miyama Tunnel, located just before the end of the line at Tsuruga Station, is less than 800 meters long. It is much shorter than the Shin-Hokuriku Tunnel (approximately 19.8 km) and the Kaga Tunnel (approximately 5.5 km). However, this tunnel was one of the tunnels that required particular environmental consideration in the construction of the Hokuriku Shinkansen extension. Miyama is one of the water sources for the Nakaikemi Wetland - a wetland designated with Ramsar Convention on Wetlands, and it was necessary to minimize the impact on the groundwater.

Why is it Regional Decarbonization Now? Toward Promotion of the Regional GX

In October 2020, the Japanese government declared its goal of becoming carbon neutral by 2050 with zero emissions of greenhouse gas overall. A major key to achieving this goal is the "local area," where small and dispersed emission sources, such as small and medium-sized businesses and households, are concentrated. We asked Gen IKEMOTO of Social Innovation Div., GX Promotion Dept., Executive Consultant; Junichiro SAITO of Climate and Resources Policy Sec.; and Toru TSUNEOKA, also of Regional Decarbonization Sec., about how far regional decarbonization has progressed, what the challenges are, and how it should be promoted in the future.

What is Comprehensive Entrustment of Infrastructure to Private Sector?

How to protect infrastructure such as roads with limited personnel and budgets is a major issue for local governments. One promising method that is garnering attention is "Comprehensive Entrustment to Private Sector." We spoke with three people from PACIFIC CONSULTANTS who have pioneered this field and have achieved many successes: Nobutaka INAMITSU of the Spatial Creation Section, Infrastructure Management Dept., Transportation Infrastructure Div.; Kazuya MURAMATSU of the Infrastructure PPP Section, PPP Management Dept., Social Innovation Div.; and Shigeto TANAKA of the Infrastructure Management Section, Transportation Infrastructure Dept., Osaka Headquarters.
