Mitsubishi Estate announces
Tokiwabashi District Redevelopment Project A large-scale redevelopment encompassing over three hectares adjacent to Tokyo Station
Mitsubishi Estate Co., Ltd. (hereinafter “Mitsubishi Estate”) along with the appropriate rights holders announces
that they have initiated the urban planning procedures for the “Tokiwabashi District Redevelopment Project”
(hereafter “the Project”), a large-scale redevelopment project in the Tokiwabashi District, an area adjacent to the
Tokyo Station. After the deliberation of Tokyo City Planning Council and the agreement of National Strategic
Special Zone Advisory Council, the Project will proceed to obtain authorization by Prime Minister Shinzo Abe, as a
designated project for the National Strategic Special Zone Program within Tokyo.
The Project is set to encompass 3.1 hectares – the largest in the vicinity of Tokyo Station. The project will comprise
of four developments carried out in stages over a 10-year period, while maintaining the infrastructure functions
including sewage facilities and electrical substations within the district. Additionally, the Project entails the
development of a 390m super high-rise tower that will become a new landmark for the city of Tokyo, and a
spacious plaza measuring approximately 7,000m2 to support the area as a bustling global center.
Through the Project, Mitsubishi Estate will drive forward Tokyo’s urban regeneration and contribute to its
international competitiveness.
Contributions to urban regeneration through the Project
1. Renewal of urban infrastructure (sewage pumps, etc.), creation of a pedestrian network,
open plaza, etc.
2. Creation of a hub to enhance international competitiveness (finance/ business exchange
and urban tourism)
3. Creation of superior disaster management and an eco-conscious urban environment

Project Features
1. Renewal of urban infrastructure
(1) Renewal and redevelopment of sewage pumps, electrical substation and a parking lot
Through constant redevelopment and phased reconstruction, we intend to rebuild key infrastructure
functions with no disruption to operations.
(2) Connection to Tokyo Station and its surrounding area via a underground pedestrian network
We intend to create an underground pedestrian network running east and west, and underground access to
the intersection of Eitai-dori Street and the Nihonbashi Exit of Tokyo Station, thereby strengthening the
access of the areas surrounding the station.
(3) Redevelopment of Tokiwabashi Park and creation of integrated plaza and new riverfront area (total area
exceeding 1 hectare)
2. Enhancement of Tokyo’s international competitiveness
(1) Contribution to Tokyo’s competence as a global financial hub
We intend to strengthen the financial axis from the Otemachi to Kabutocho, both districts with a
concentration of financial entities, through the creation of financial and business exchange. This is in line
with the Tokyo Metropolitan Government’s intentions for the “Tokyo International Financial Center.”
(2) Enhancement of Tokyo’s urban tourism appeal
We intend to create urban tourism facilities, capitalizing on Tokyo Station’s convenient transportation
networks.
3. Creation of superior disaster management and an eco-conscious urban environment
(1) Base for disaster management activity and accommodation of evacuees
Through the creation of a large-scale plaza and emergency power amenities, the project will serve as a key
hub in the unlikely event of a disaster with measures in place to support those unable to return home.
(2) Introduction of secure energy system and a backup water supply system
Through the introduction of high-efficiency cogeneration systems and dual-fuel compatibility emergency
power generators, in conjunction with emergency wells to provide water for miscellaneous uses (e.g.
flushing toilets), we aim to reduce disruption even when disaster strikes.
(3) Reduction in environmental load through eco-conscious efforts
We intend to achieve level 3 (PAL, ERR) certification from submission to the Building Environment Plan
of the Tokyo Metropolitan Government, and an S rank under the CASBEE evaluation system.
