The W350 Project is a proposed wooden skyscraper in central Tokyo, Japan, announced in 2018. The skyscraper is set to reach a height of 350 meters with 70 floors, which upon its completion will make it the tallest wooden skyscraper, as well as Japan's tallest building. The skyscraper is set to be a mixed-used building including residential, office and retail space. It is scheduled to be completed in 2041, to mark Sumitomo Forestry's 350th anniversary.
