Mitsui Fudosan Co., Ltd.

Mitsui Fudosan Co., Ltd., together with the various land owners, is advancing the Nihonbashi Muromachi East District Development Project, a large-scale mixed-use redevelopment project covering 5 blocks in the Nihonbashi Muromachi area of Chuo Ward, Tokyo. On February 1, 2014, the Muromachi Furukawa Mitsui Building and the Muromachi Chibagin Mitsui Building will be completed as the second phase of this project. COREDO Muromachi 2 and COREDO Muromachi 3, which are retail properties located in the lower floors of these buildings, are scheduled to open on Thursday, March 20, 2014. Moreover, the renovation of Fukutoku Shrine in the last remaining block is scheduled to be completed in autumn 2014.

The Muromachi Furukawa Mitsui Building is the largest building in this project, and comprises the three sections of rental housing (18th to 21st floors), offices (7th to 17th floors), and retail properties (1st basement floor to 6th floor). The Muromachi Chibagin Mitsui Building, which faces Chuo Dori Street, comprises the two sections of offices (8th to 16th floors), and retail properties (1st basement floor to 4th floor).

In the office section, a standard floor is provided together with the capability of varying the floor plan and size: it can be adjusted to meet tenants’ needs. Furthermore, the advanced functionality offices back up business continuity plan (BCP) measures for tenant companies. These include featuring a variety of eco-friendly equipment, including LED lighting and electric blinds. In response to needs for safety and security, we will broadcast disaster information via digital signage, provide electricity (15VA/m²) to rental areas via an emergency power supply which can last for 72 hours, install elevators of the S09 class boasting the highest rank of earthquake protection, and ensure all floors possess storage units with provisions for use in the event of a disaster.

The building's exterior employs a design concept of Norihiko Dan and Associates, and the design possesses special lower-level features that are consonant with each street the building faces, while harmonizing with the nearby historical buildings in the neighborhood.

Chuo Dori Street

The low-rise skyline will be aligned to harmonize with the Mitsui Main Building and other historical buildings.
The decoration with its gold-colored louvers on the big windows facing the street recalls the former gold mint “the Kinza” that once existed in the Edo Period in the Nihonbashi area. The building is stylishly designed with many different aspects depending on the angle of the light. (Muromachi Chibagin Mitsui Building)

Edo Zakura Dori Street

The existence of the cinema complex in the lower levels of the building will be expressed by a loggia evocative of a typical Western theater. With its delicate and refined Awaji tiles, the building will creatively harmonize with the bustling street. (Muromachi Furukawa Mitsui Building)
Paired with the Muromachi Higashi Mitsui Building through a design element based on a traditional lamp motif, the two buildings will serve as a “gateway” for visitors. (Muromachi Chibagin Mitsui Building)

Naka Dori Street

Naka Dori Street: The design achieves a sense of scale at the eye level, for example the traditional eaves (noki) and short eaves (hisashi) have been unified to harmonize with the neighboring streets lined by older traditional shops.

Features of the Nihonbashi Muromachi East District Development Project

Features of the Nihonbashi Muromachi East District Development Project

In the development of the Nihonbashi Muromachi East District, Mitsui Fudosan has taken advantage of the fact this is an integrated development covering many blocks and is implementing many initiatives aimed at reenergizing the town by making the most of the streets surrounding the district.

Chuo Dori Street

To form unified views from the perspective of pedestrians, Mitsui Fudosan strove to achieve harmony with such historic treasures as the Mitsui Main Building, which has been designated as a nationally important cultural property, and the Mitsukoshi Nihonbashi Main Store, which is one of Tokyo's historic buildings. We have also applied this “historic style” to the exterior design of new buildings, which have a low skyline approximately 31 meters high and colonnaded lower levels with large pillars.

Edo Zakura Dori Street

In line with this project, Edo Zakura Dori Street will see an extension up to Chuo Dori Street of the cherry tree planting begun near the Bank of Japan by Chuo Ward, and have its sidewalks widened, thereby forming a bustling street with a Japanese atmosphere.

Naka Dori Street and Ukiyo Koji Alley

The project gives priority to the safety of walkers by preserving sidewalks and vacant land within the project area that lie along Naka Dori Street and Ukiyo Koji Alley that has been positioned as an approach to the Fukutoku Shrine. Furthermore, Naka Dori Street and Ukiyo Koji Alley will be made enjoyable for walking by having electric cables and power lines buried underground and by being covered with a stone pavement.

Edo Zakura Underpass (Tentative Name)

At the first basement level, an underpass for pedestrians has been built beneath both Edo Zakura Dori Street and Naka Dori Street, and together with the underground parts of the adjacent buildings forms a public space that can be used as a plaza in front of the station.
In conjunction with the work to expand the underground area beneath Chuo Dori Street, efforts have been made to enhance the pedestrian network. Digital signage has been installed, and in normal times this will aid people to enjoy walking around the underground plaza, and in the event of a natural disaster it will provide disaster-related information to assist people unable to return home.

Overall environmental features in the Nihonbashi Muromachi East District Development Project

In the Muromachi Furukawa Mitsui Building and the Muromachi Chibagin Mitsui Building, Mitsui Fudosan is aggressively implementing various smart city-related initiatives aimed at reducing the environmental burden.

Buildings

• Mitsui Fudosan has achieved about a 25% reduction compared to the standard PAL value for the offices, which are the main building applications, by using high-performance heat-reflective glass and other measures, thereby reducing the air conditioning burden. Furthermore, the project has also addressed the global warming phenomenon by effectively introducing greenery and water-retentive paving.

Electric facilities

• As optimum area-specific energy-use measures, this development project has centralized all special power substation equipment in the Muromachi Higashi Mitsui Building, and implemented unified control of the energy used in the Muromachi Furukawa Mitsui Building and the Muromachi Chibagin Mitsui Building, thereby achieving highly efficient operation of equipment together with saving energy.

Air conditioning heat source equipment

• For heat sources also, in the same manner a Tokyo Metropolitan Government-certified District Heating and Cooling (DHC) system has been centralized within the Muromachi Higashi Mitsui Building, for which construction has been completed. The system supplies steam and cold water to the Muromachi Furukawa Mitsui Building and the Muromachi Chibagin Mitsui Building, thereby efficiently supplying energy to the entire area.
• In addition to BEMS (Building Energy Management System), the redevelopment project uses an on-demand type of heat source optimum control system that enables the most efficient operation of all heat source equipment based on the past operational performance of air conditioning heat source equipment and from weather prediction functions, thereby achieving efficient energy management. By these means, we have not only reduced primary energy consumption and the volume of carbon dioxide generated: we are also easily able to respond to regional demands for conserving electric power.

Overall BCP features in the Nihonbashi Muromachi East District Development Project

• In the Nihonbashi Muromachi East District Development Project, a 3,000 m² underground plaza has been developed, centered on the Edo Zakura Underpass (tentative name). Mitsui Fudosan intends that in the event of a natural disaster, the plaza will be opened to serve as an evacuation center and assist people who are unable to return home. Relevant facilities inside the plaza can support these people for three days, and there will be about 400 m² of disaster supply stockrooms inside the redevelopment area centered on the Fukutoku Shrine block, together with emergency food supplies and simple toilets, among other provisions.
• Furthermore, the project will provide information when a disaster occurs via digital signage installed in the Edo Zakura Underpass (tentative name), which aims to be not merely a space but an area with sophisticated disaster-readiness capabilities covering the aspects of provisions, the environment, and information.
