| Japanese developer Mitsui Fudosan to build Japan’s tallest wooden structure in Tokyo. |
The building will have a total floor area of approximately 28,000 square meters. It will be 84 meters tall, far surpassing the five-story pagoda of Toji Temple (approximately 55 meters), the tallest existing wooden building in the country. Takenaka Corporation will be in charge of the design and construction. The project is scheduled for completion in July 2026.
The 2,502 square meters construction site is located at Nihonbashi-Honcho, Chuo-ku, Tokyo. The building will be a wooden/steel structure with a basement and 18 stories above ground, totaling 27,826 square meters. The foundation will be constructed with piles. More than 1,000 cubic meters of lumber will be used for structural materials. The wood will be obtained mainly from a 5,000-hectare forest owned by a Mitsui Fudosan Group company in Hokkaido. The main structural members will be made of "MOENWOOD," a fire-resistant laminated wood developed by Takenaka Corporation to improve safety against fire.
The use of wood is expected to reduce carbon dioxide emissions during construction by approximately 20% compared to a typical office building of the same size. Once completed, the building will be used not only as rental office space, but also as a base for Mitsui's life science business, which is expanding mainly in the Nihonbashi area.
The company representative says, "It is expected to be an attractive place that will provide employees and visitors with the warmth and comfort that only wood can offer, and will create new value in urban development and landscaping in the heart of the city.” (2023/05/30)
