Main Features and Plan Outline

This leading project is one of five urban redevelopment projects of the surrounding area scheduled to be completed first along the Nihonbashi river. Adjacent to the famous ‘Nihonbashi Bridge’, a symbol of the city, the Project will become a new landmark in the Nihonbashi area, befitting its location through the following measures.

1. Urban Oasis Open to the Sky and River is Born in Nihonbashi where Tradition and Innovation Coexist in Harmony

Since the Edo period (1603-1867), Nihonbashi has flourished as a cultural, economic, and commercial center, marking the starting point of five major roads (Go-kaido roads) connecting the capital Edo (present-day Tokyo) with other parts of Japan. Currently, Nihonbashi continues to evolve as an urban center where tradition and innovation coexist in harmony, with a mix of long-established companies, retail facilities and business bases of cutting-edge companies.

In the Project, several terrace decks with views of the Nihonbashi river and plazas that create urban vitality will be built, allowing visitors and workers to enjoy an enriching and comfortable environment surrounded by open sky, water and greenery while in central Tokyo. In addition, plans call for setting up a boarding/alighting facility for sightseeing buses. Together with the river cruising network associated with the existing Nihonbashi Boarding Dock, the Project will provide various means of access to the Nihonbashi area, including access for visitors from nearby areas for micro-tourism purposes.

Zone C (skyscraper building), where the main tower will be located, has a unique shape with a sense of dynamism that harmonises with the cityscape. From the residential facility and hotel lobby situated more than 200 meters above ground level, people will be able to enjoy stunning views of the Tokyo Bay area and Tokyo Tower. There are also two outdoor sky gardens, one in the upper floors and the other in the lower floors where office workers can enjoy the seasonal breezes and a view of the famous Nihonbashi bridge, a symbol of the area, and the Tokyo Sky Tree. Office workers will be able to adopt a variety of work styles while enjoying a change of pace and refreshing their body and mind.

2. Excellent Access and Large-scale Mixed-use Facility Encompassing Six Uses

The Project is made up of three zones: A, B and C. The main tower is located in Zone C (skyscraper building: 52 floors above ground, approximately 284 meters high) a large-scale mixed-use facility with six uses: offices, hotel, residential facility, retail, MICE and business support facilities.

The first basement level of Zone C will be directly connected to Nihombashi Station on the Tokyo Metro Ginza Line and Tozai Line via an underground walkway planned for construction. In addition, a new ticket gate will be installed in Nihombashi Station on the Toei Asakusa Line. As a result, Zone C will make it possible to access Haneda Airport in about 30 minutes and Narita Airport in about 60 minutes without transferring lines.

Furthermore, in the future, plans call for the construction of an underground passageway from Tokyo Station’s Nihonbashi Exit to Nihombashi Station as part of the development of surrounding districts*. This planned underground passageway is expected to further improve transportation convenience.

Project Overview

Zone A
The Nihonbashi Nomura Building was completed in 1930 by the Japanese architect Takeo Yasui, who advocated a “free form” style of architecture. The building features an eclectic design style that incorporates Eastern design elements by removing columns with wall finishes while adhering to a traditional three-layer structure. As a historically significant modern building, it has been designated as a Tangible Cultural Property of Chuo City. In the Project, efforts will be made to create even more urban vitality throughout the Nihonbashi area while carrying on Nihonbashi’s traditions and culture by preserving and making use of the elegant exterior of the Nihonbashi Nomura Building.

Zone B
The Project will create a comfortable urban area that complements the waterfront of the Nihonbashi river by fostering scenery that blends in seamlessly with Zone A, which is a Tangible Cultural Property of Chuo City. Zone C will be accessible via a deck on the 3rd floor above ground, creating a commercial space that leads to the liveliness along the Nihonbashi river. Approximately 50 residential units will accommodate a variety of lifestyles with the serenity of the waterfront.

3.　Creating a Safe, Secure and a Sustainable City; Providing an Advanced Way of Working and Living

In response to the recent external environment, the Project will provide safe, secure and sustainable facilities through measures to reduce environmental impact and implementing BCP to achieve a decarbonized society.

(1) Measures to Reduce Environmental Impact with a View to Achieve a Decarbonized Society

In the Project, Mitsui Fudosan will promote energy conservation at various facilities as an effort to reduce environmental impact. The office areas of Zone C are scheduled to obtain ZEB certification, while the residential facility area of Zone C is scheduled to obtain ZEH certification. The entire Zone C plans to obtain DBJ Green Building certification.

• ZEB certification
  A Net Zero Energy Building (“ZEB”) is a building aimed at zero energy consumption while maintaining a comfortable indoor environment and that is capable of making its energy consumption net zero through energy savings and energy creation. ZEB certification is a third-party certification program for energy performance that ranks buildings as ZEB, Nearly ZEB, ZEB Ready, or ZEB Oriented based on the Building-Housing Energy-Efficiency Labeling System (BELS) using the Building Energy Index (BEI, ratio of design primary energy consumption to standard primary energy consumption) and the use of renewable energy.
• ZEH certification
  A Net Zero Energy House (“ZEH”) is a house designed to target zero net primary energy consumption on an annual basis. This is achieved by introducing renewable energy after realizing energy efficiency while maintaining comfortable indoor environments, along with improving the insulation performance of the exterior and other factors. Multi dwelling housing can obtain the ZEH-M, Nearly ZEH-M, ZEH-M Ready and ZEH-M Oriented certifications depending on the rate of reduction in primary energy consumption.
• DBJ Green Building certification
  A program for certifying “real estate that is environmentally and socially conscious” It is administered by the Development Bank of Japan and Japan Real Estate Institute and assigns a rank from one to five stars. Along with overall environmental performance, it evaluates “diversity and local environment considerations” as well as stakeholder collaboration.

(2) Installation of an Energy Center to Reduce Environmental Impact while Providing Safe and Secure BCP

As part of the Project, an Energy Center will be installed to supply “electricity” and ”heat” in the Zone C basement.

In addition to centralizing the necessary energy facilities in multiple redeveloping areas in one location, the Project will also utilize exhaust heat through the introduction of CGS*, an eco-friendly and energy resilient system, that generates electricity necessary for BCP required for tenants in the event of a grid power interruption (blackout) through the use of reliable medium-pressure gas power generation. We plan to supply electricity and heat to the entire Project zones and studying the possibility to supply electricity to the surrounding areas to be developed in the future.

• A Cogeneration System (“CGS”) is an energy-efficient and energy-saving facility that uses exhaust heat generated during power generation to supply cooling and heating to buildings.

4．Exterior Design that Embodies Innovation and Harmony by Pelli Clarke Pelli Architects, Inc.

Pelli Clarke Pelli Architects, Inc., which designed Nihonbashi Mitsui Tower and Nihonbashi Muromachi Mitsui Tower, has been appointed as the design architect for the Project.

The "swinging setback" design which is based on the image of a kimono, a river, and a Noren (Japanese style short curtain) is a distinctive yet global design suitable for an international financial hub that is in harmony with the Nihonbashi cityscape. The smooth curves of the exterior express the unity of various uses of the building.
