Tokyo Midtown Nihonbashi to anchor Nihonbashi River Walk redevelopment

Mitsui Fudosan and Nomura Real Estate announced April 21st that the large-scale Nihonbashi 1-chome Central District Type 1 Urban Redevelopment Project in Tokyo’s Chuo Ward will be named Tokyo Midtown Nihonbashi, anchored by a 284-meter tower that will rank among the tallest buildings in central Tokyo.

The development will become the fourth Tokyo Midtown complex, following projects in Roppongi, Hibiya and Yaesu.

The project is the first development within the broader Nihonbashi River Walk area along the Nihonbashi River, part of wider efforts to revitalize the historic waterfront district.

The site is directly connected to Nihonbashi Station serving the Tokyo Metro Ginza and Tozai lines and the Toei Asakusa Line. Mitsukoshimae Station on the Tokyo Metro Hanzomon Line is a three-minute walk away, while JR Tokyo Station is about eight minutes on foot.

The redevelopment spans roughly 3 hectares and is organized into four blocks labeled A through D. Its centerpiece will be the Nihonbashi Nomura Mitsui Tower, also referred to as “The Tower,” located in Block C.

The building will rise 52 stories above ground with five basement levels and reach a height of about 284 meters. Total floor area will be approximately 374,800 square meters on a site of roughly 15,560 square meters.

An underground energy center will supply electricity and heat to the development and surrounding district as part of the area’s broader energy infrastructure.

Floors 39 through 47 of the tower will house the Waldorf Astoria Tokyo Nihonbashi, a 197-room luxury hotel operated by Hilton under its top-tier Waldorf Astoria brand. The hotel is scheduled to open in autumn 2027.

Above it, floors 48 through 51 will feature the Waldorf Astoria Residences Tokyo Nihonbashi, the brand’s first rental residences in the Asia-Pacific region. The development will include 71 units ranging from about 60 to 430 square meters, with services linked to the hotel.

Retail space from basement level one through the third floor will connect with the adjacent Nihonbashi 1-chome Mitsui Building (“South”) in Block D via basement level one and the second floor above ground, creating an integrated commercial zone of about 20,000 square meters.

Floors five through eight will house one of central Tokyo’s largest MICE and business support facilities, including two halls of roughly 1,500 square meters each and 12 conference rooms totaling about 1,400 square meters.

Office floors will occupy both lower and upper sections of the tower, featuring some of the largest floor plates in the area. Lower-rise offices on floors 10 through 20 will offer standard floor plates of roughly 6,300 square meters, while upper-level offices on floors 22 through 38 will have floors of about 4,300 square meters. Outdoor sky gardens are planned on the 10th and 21st floors.

Other components of the redevelopment include the preservation and reuse of the historic Nihonbashi Nomura Building Old Wing, a Chuo Ward-designated tangible cultural property. The structure will retain its exterior while being converted to retail space on the first and second floors and office space above.

Block B, named Nihonbashi Riverside Terrace, will introduce a new mixed-use building facing the Nihonbashi River. The seven-story structure with two basement levels will feature waterfront retail on the first through third floors and 48 residential units above.

Meanwhile, COREDO Nihonbashi, the retail complex occupying basement level one through the fourth floor of the Nihonbashi 1-chome Mitsui Building in Block D, will close in October 2026 and reopen as part of the Tokyo Midtown Nihonbashi commercial zone following redevelopment.

Construction of the overall project is scheduled for completion in September 2026, with the full Tokyo Midtown Nihonbashi complex expected to open in autumn 2027.
