TOKYO TORCH Tokiwabashi Tower
Mitsubishi Jisho Sekkei Inc.

Located directly north of Tokyo Station, one of Japan’ s largest railway hubs, the Tokyo Torch redevelopment district isenvisioned as a light of hope illuminating Japan. The district sits within a National Strategic Special Zone, intended tostrengthen Japan’ s international economic competitiveness, and will be a new center of finance and business. It will
include Torch Tower, projected to be Japan’ s tallest building at 390 meters when completed in FY2027; TokiwabashiTower; an Electrical Substation Building; a Sewerage & Waterworks Bureau Building; Tokyo Torch Park; andTokiwabashi Park. Four existing dilapidated buildings are being demolished and replaced in stages in conjunction withthe renewal of urban infrastructure including electrical and water facilities. Tokiwabashi Tower, a 38-story,
212-meter-high mixed-use building, is the first element of the project to be completed.
Soaring among the tallest mixed-use buildings around Tokyo Station, Tokiwabashi Tower is a next-generation
business center offering quality office space that supports diverse work styles and innovation while providingoutstanding environmental and disaster-safety performance. The building’ s form suggests a blade cutting open thefuture, while the upper section is wrapped in a grid that creates depth and shadow—an exterior design fitting for acenter of international finance. The grid blocks sunlight much like kigoshi (wooden latticework) and shoji(paper-covered sliding doors) do in traditional Japanese architecture, gently connecting the interior and exterior
environments.
The first underground floor and first two above-ground floors are occupied by restaurants and bars, the third floor is acafeteria, and the eighth through thirty-seventh floors are offices. The terrazzo walls in the second-floor lobby and on
the third, eighth, and ninth floors feature motifs inspired by the walls of Edo Castle and the stonework of Tokiwa
Bridge. The abundant use of familiar natural materials such as wood and stone, long utilized in Japanese architecture,
is intended to enhance productivity and satisfaction among workers. Workers can directly access MY Shokudo, thecafeteria and lounge on the third floor, from any office floor. While this facility primarily serves employees in thebuilding, there is also an event hall with a kitchen to encourage interaction, and at night the facility can be used bypeople who live in the neighborhood.

A Structural Design that Puts Safety FirstThe building site for Tokiwabashi Tower is among the smallest and most irregularly shaped lots of the entire
redevelopment district, hemmed in by the Nihombashi River, a high-speed underground highway, and an electricalsubstation. To ensure that the tower is competitive with other large-scale office buildings, it was necessary to expand
the floor plate on the upper levels. Starting on the eighth floor, floor area is expanded by angling the structural pillars
to overhang the lower floors. The appropriate placement of dampers and braces ensures that the building remains
safe in the event of earthquakes and typhoons, which are common in Japan.

Artwork In the Colors of Japanese Culture

To support young artists, the interior of Tokiwabashi Tower features eighteen contemporary works by artists at thecutting edge of the art world, primarily from Japan and the rest of Asia. These works, curated to reflect the vibrantcolor themes of Japanese festivals and kabuki theatre, thrill the senses of visitors and add excitement to thebuilding’ s interior.

TOKYO TORCH ParkAt the center of the redevelopment district (including Tokiwabashi Tower and the buildings that will be completed incoming years) is a large plaza measuring about 7,000 square meters, available for both everyday use and special
events such as concerts, sports, and markets. The plaza also showcases specialty products from throughout Japan,
from the colored koi fish in the pond and the grass planted on the ground to the landscaping plants, providing anopportunity for international visitors to learn about the Japan beyond Tokyo.

Facing this plaza are Tokiwabashi Tower’ s three floors of restaurants with adjoining terraces, offering a pleasantspace for enjoy outdoor eating that is useful in the era of Covid-19. At night, the glassed-in interiors float like lanterns,
creating a scene evocative of an ukiyoe woodblock print. By intentionally developing the base of the tower in this way,
the project continues an urban history and culture dating to the Edo period (1603–1868) of welcoming a diversity ofactivities by people working, eating, visiting from abroad, and taking family outings, thus adding to the energy of thecity. Future stages of the project will build on this foundation with the Water & Sewerage Bureau Building, theElectrical Substation Building, and the Torch Tower.

About Mitsubishi Jisho Sekkei
The roots of Mitsubishi Jisho Sekkei lie in the Marunouchi Architectural Office, the architectural design firm founded in1890 which designed Japan’ s first modern office building, the Mitsubishi Ichigokan (Building No.1). Over thesubsequent decades, as the country modernized, the firm went on to design a series of iconic brick buildings in thecentral Marunouchi district of Tokyo, the national capital. In the 1960s, responding to rapid economic growth and theburgeoning demand for office space, the area was transformed into a harmonious central business district, with newbuildings designed to conform to a uniform height of 31meters. In the 21st century, these buildings have been
replaced with high-rise towers and the area has been reimagined once more as a lively district with vibrantcommercial and cultural functions. Mitsubishi Jisho Sekkei has led the development and renewal of the Marunouchi
district across three generations, allowing it to bring unparalleled experience to bear in architectural and urban
development projects throughout Japan and the world.
