Mitsui Fudosan and Takenaka Corporation are planning to build a 17-story wood-frame office tower in Tokyo’s Nihonbashi district. With a proposed height of 70 meters, this would be the tallest wooden building in Japan.
Construction is tentatively scheduled to start in 2023 with completion in 2025. The building’s floor area would be 26,000 sqm (280,000 sq.ft), and be constructed from 1,000 cubic meters of domestic lumber. The main structure would be a hybrid that incorporates Takenaka’s fire-resistant laminated wood with materials sourced from Mitsui-owned forestry in Hokkaido. Carbon dioxide emissions would be 20% less than those when constructing a standard steel-frame office building of the same size and scale.
Mitsui Fudosan Group owns approximately 5,000 hectares of forestry in Hokkaido, all of which has been certified by the Sustainable Green Ecosystem Council.
