TOKYO-If you think about the tallest structures in Japan, the capital city’s iconic towers immediately come to mind, with Tokyo Tower standing at 333 meters in height, and Tokyo Skytree, the tallest tower in the world, measuring in at 634 meters.
Now there’s a new building set to jut out on the urban horizon, and this one is making news not only for its height, but the innovative materials it will be made from.
Japan’s Sumitomo Forestry unveiled plans for the new skyscraper recently, dubbing it the “W350 Project“, as the structure is set to be 350 meters in height, and completed by 2041, to mark the 350th anniversary of the company’s operations. The origins of the company can be traced back to 1691, when they were responsible for managing the forests beside the Besshi Copper Mine in Shikoku’s Ehime Prefecture, and this forestry connection is one that takes centre place in the upcoming building, which will incorporate 185,000 cubic meters (6.5 million cubic feet) of wood in its construction.
According to the company, the level of skill and engineering involved in the new building exceeds that of current skyscrapers, and was conceptualised by Sumitomo’s Tsukuba Research Laboratory, as part of their research and development activities aimed at designing environmentally conscious future technologies in the world of construction.
The building, which will be created in conjunction with architecture firm Nikken Sekkei, will be an innovative wooden steel hybrid, using a 9:1 ratio of wood to steel. By utilising a brace tube structure in its design, diagonally placed braces will protect the building from outside forces like earthquakes and strong winds.
There will be 70 floors above ground, with shops, offices, hotels and residential spaces within the building, along with wrap-around balconies containing greenery, and wildlife extending throughout the complex, to create a forest environment.
Once completed, the building, which is estimated to cost 600 billion yen, will become the world’s tallest wooden structure, and the tallest building in Japan, standing 50 meters higher than Abeno Harukas in Osaka, currently the country’s tallest building, at 300 meters.
The new complex will be located near Tokyo Station, in the city’s heavily built-up Marunouchi financial district.
The innovative project aims to replace concrete and decrease carbon dioxide levels in order to pave the way for more environmentally friendly buildings in the city. The wooden skyscraper is part of the company’s plans to create urban environments where humans and wildlife can flourish together, connecting living creatures and strengthening biological diversity in the country’s concrete jungles.
Bringing wildlife back into the city and creating buildings with more environmentally conscious designs is an admirable goal, and one we hope to see grow, like a forest, in more cities around the country, and the world, in the future.
