The planned structure is a hybrid wood and steel structure made from 90% wooden materials.

Sumitomo Forestry said that the amount of timber used in the W350 Plan (185,000 m3 ) is equivalent to approximately 8,000 wooden houses.

There will be trees and foliage on balconies at every level.

The cost of project is approximately $5.6 billion, almost twice the cost of a conventional high-rise of the same size built with current technology.

In 2010, the Japanese government enacted the Act for Promotion of Use of Wood in Public Buildings, promoting a shift to wooden structures for public buildings.

Sumitomo Forestry said:

“The aim is to create an environmentally-friendly and timber-utilizing cities where they become forests through increased use of wooden architecture for high-rise buildings”

Adding:

“The devastation of domestic forests due to insufficient maintenance is becoming a problem. Increased timber demand will promote replanting and contribute to revitalization of forestry and local community through producing seedlings to encourage sustainability of forests.”
