TOKYO TORCH: large-scale redevelopment with tallest high-rise building in japan

located at the historic tokiwabashi district in japan, ‘TOKYO TORCH’ is currently undergoing large-scale redevelopment including two skyscrapers. spanning 31,400 sqm, the project led by mitsubishi jisho sekkei aims to further enhance the utilization of this area. according to sou fujimoto — who is also involved in the project — ‘torch tower’, one of the two skyscrapers, is set to become japan’s tallest building.all images courtesy of mitsubishi jisho sekkei inc.

‘TOKYO TORCH’ will maintain the region’s valuable legacy as japan’s core economic district. however, apart from purely economic functionality, mitsubishi jisho sekkei sought to generate surprise, joy, pride, calmness and happiness into this project. the design team is led by koji matsuda as head of the project, with next-generation architects and urban landscape designers: sou fujimoto, yuko nagayama, and takanori fukuoka. four new major buildings planned for the district including tokiwabashi tower, torch tower, electrical substation building, and waterworks and sewerage bureau building, while a large plaza will cover approximately 7,000 sqm between the two towers.TOKYO TORCH viewed from the north

the plaza will connect to a newly landscaped waterfront along nihombashi river, a historically important tokyo waterway, as well as to tokiwabashi park. moreover, it will link to an open-air walkway that spirals around the first eight floors of the ‘torch tower’, leading to a rooftop garden. thanks to the seamless connections between the outdoor spaces and the two towers, it will be possible to hold events integrating all facilities. in addition, the extensive outdoor areas can be used as open-air offices or spots for a refreshing break, enhancing the quality of work for district employees.

‘tokiwabashi tower’ scheduled for completion in june 2021, will consist of cafeterias and common lounges for those employed in the building, while guaranteeing security. the architects sought to incorporate into the project secure systems currently demanded of architecture, such as extensive outdoor space, expanded options for moving around the city, and highly functional interior spaces while empowering users to experience the excitement and value of the real-world space.torch tower, exterior viewed from west side of jr tokyo station

‘torch tower’ scheduled for completion in 2028, will take shape as the tallest high-rise building in japan. the team sought to generate an environment full of creativity, where nature, architecture, and human activity are seamlessly integrated. an open-air observation deck will be located at the top of the building, while a world-class hotel will be invited to occupy the 57th through 61st floors, which enjoy sweeping views across tokyo. furthermore, the pedestal, comprising the first below-ground floor through the sixth above-ground floor, will feature a retail zone and, from the third through sixth floors, a multipurpose hall. meanwhile, a verdant open-air walkway will encircle the pedestal. tokiwabashi tower, exterior viewed from the southeast

in an attempt to achieve a tower of unusual height in a country that experiences frequent earthquakes and typhoons, the architects — together with structural engineers with outstanding experience and skills — combined an outer-shell vibration control structure that effectively uses outer bracing to envelop the entire building like a shell. their design significantly reduces sway in the event of an earthquake or strong wind and ensures the highest level of seismic resistance in the country. the plaza will be equipped with features such as large electronic billboards and wi-fi so that it can serve the surrounding area as a base for disaster recovery activities in case of emergency. in addition, the multipurpose hall will be made available as an all-weather temporary shelter, offering greater support for stranded commuters.TOKYO TORCH viewed from JR tokyo station nihombashi exit
