Tokyo, Japan, April 21, 2026 - Mitsui Fudosan Co., Ltd., a leading global real estate company headquartered in Tokyo, and Nomura Real Estate Development Co., Ltd. (hereafter, “Nomura Real Estate”), announced that the overall district name for the Nihonbashi 1-Chome Central District Category 1 Urban Redevelopment Project, in which it is involved, has been decided as “Tokyo Midtown Nihonbashi.”

This project, the first phase of redevelopment for the Nihonbashi River Walk area surrounding the Nihonbashi River, leverages the rare waterfront space in central Tokyo to create a new urban experience that brings the river and the city together. The development will feature a large-scale mixed-use complex with a range of urban functions, including offices with one of the largest floor plates in the area; Waldorf Astoria Tokyo Nihonbashi, high-quality and sophisticated retail facilities, a luxury hotel by Hilton; the Waldorf Astoria Residences Tokyo Nihonbashi, branded under Waldorf Astoria Hotels & Resorts; and one of the largest MICE facilities in central Tokyo, featuring a hall with a total capacity of 1,600.

The ongoing underground relocation of the Metropolitan Expressway will completely transform the riverside landscape along the Nihonbashi River, creating an open urban space defined by expansive sky and water and turning Nihonbashi into an area that attracts global attention. In anticipation of this vision, Tokyo Midtown Nihonbashi will help shape Tokyo’s future urban development as a pioneering initiative that presents a new model for the city center where waterfronts and urban functions are seamlessly integrated.

■The Background and Significance of Naming the Overall District “Tokyo Midtown Nihonbashi”

The Nihonbashi 1-Chome Central District is located at the heart of an area that has been an international hub for commerce, finance, and culture since the Edo period. Mitsui Fudosan and Nomura Real Estate Development have long been engaged in efforts to enhance the urban value of this area.

The overall district has been named “Tokyo Midtown Nihonbashi” and will be reorganized under the Tokyo Midtown brand. Tokyo Midtown has set forth a vision of sharing JAPAN VALUE (new values, sensibilities, and talent) with the world. This project marks the fourth Tokyo Midtown following Roppongi, Hibiya, and Yaesu. By combining Nihonbashi’s unique history with visions of the future, the development will integrate a wide range of urban activities such as working, socializing, staying overnight, and living. As a landmark mixed-use development leveraging its waterfront setting, it will establish a new urban brand to be shared from Nihonbashi to Tokyo and the world.

With this reorganization, COREDO Nihonbashi, which opened in 2004, will temporarily close and be reborn as part of the Tokyo Midtown Nihonbashi retail zone. The COREDO Muromachi 1, COREDO Muromachi 2, COREDO Muromachi 3, and COREDO Muromachi Terrace in the Nihonbashi Muromachi area will continue to embody the concept of CORE + EDO (the heart of Edo/Tokyo). Together with the retail zone of the Tokyo Midtown Nihonbashi, the COREDO series will continue to showcase the diverse appeal of the entire Nihonbashi area.

■Overview of Each Zone

The project consists of four zones: A, B, C, and D. Each has its own character, and together they form a new international urban landscape in Nihonbashi. The names of the buildings in each zone have also been decided as follows.

(1) Zone A - Nomura Nihonbashi Heritage Building

The exterior of the Nomura Nihonbashi Heritage Building, which is a designated tangible cultural property of Chuo City, is to be preserved and utilized. Completed in 1930, this historical building will be carried forward into the future with its lower floors reborn as a retail facility, creating a symbolic urban space in which tradition and innovation co-exist in harmony.

(2) Zone B - Nihonbashi Riverside Terrace

Nihonbashi Riverside Terrace, a mixed-use facility facing the Nihonbashi River, will be developed with waterfront retail facilities and 48 residential units, creating an urban environment where people can experience water and greenery in the heart of Tokyo. By forming a continuous walkable promenade connecting the river and city, it will further enhance the unique waterfront appeal of Nihonbashi.

(3) Zone C - Nihonbashi Nomura Mitsui Tower (also known as: The Tower)

The mixed-use skyscraper, approximately 931 ft (284 m) tall with 52 floors above ground and 5 floors underground, will create a new skyline for Nihonbashi. Diverse urban functions will be vertically integrated to form an international urban hub connected to the waterfront space.

(4) Zone D - Nihonbashi 1-Chome Mitsui Building (also known as: South)

COREDO Nihonbashi, on the B1 to 4th floors of the Nihonbashi 1-Chome Mitsui Building, is scheduled to close in October 2026 and reopen in autumn 2027 as the retail zone for Tokyo Midtown Nihonbashi.

■Creating a Safe, Secure, and Sustainable City

The project promotes sustainable urban development that balances environmental friendliness with urban resilience. The office section was designed with the aim of obtaining ZEB Oriented certification, while the residential section acquired ZEH-M Oriented certification in April 2025. The entire district also obtained DBJ Green Building’s PLAN certification in March 2023.

The basement of Zone C will house an energy center to supply electricity and heat. By utilizing waste heat from a cogeneration system (CGS) and medium-pressure gas power generation, the project will establish a robust energy system that enables business continuity even during power outages. Supplying energy to surrounding districts is being considered for the future, to support the safety and security of the entire area.

Nihonbashi River Walk is the name of the area encompassing the redevelopment districts along the Nihonbashi River and the surrounding area, centered around waterfront spaces and a riverside pedestrian network. In this area, the Metropolitan Expressway Nihonbashi Section Underground Relocation Project and five redevelopment projects are being carried out in close coordination to create a neighborhood open to the sky and the river. This initiative is being advanced in collaboration with the national government, the Tokyo Metropolitan Government, Chuo City, the Metropolitan Expressway, private-sector businesses including redevelopers, and the local community. The combined area of the 5 development zones is approximately 27 acres (approximately 11 hectares).

■Sustainability in the Mitsui Fudosan Group

Based on the meaning of its “& mark,” “to generate new value with society through cooperation, coexistence and co-creation, we forge ahead, innovating,” the Mitsui Fudosan Group views the “creation of social value” and the “creation of economic value” as two wheels of a cart. Accordingly, we believe that the creation of social value leads to the creation of economic value, and that this economic value then creates even greater social value.

Moreover, we identified six Group Materiality priority issues when formulating our new management philosophy in April 2024. These Group Materiality priority issues are (1) Contribute to industrial competitiveness, (2) Coexist with the environment, (3) Health and Vitality, (4) Safety and security, (5) Diversity and inclusion, and (6) Compliance and governance. The Mitsui Fudosan Group will work to address each of the materialities through its core business activities and contribute to the promotion of sustainability.
