Construction & Building Materials Business

ITOCHU is working alongside strong Group companies to expand both the construction business and the building materials business, and we have established a strong presence in both these markets. In the construction business, we are engaged in the design, construction and maintenance of detached homes, plants and warehouses. Meanwhile, in the building materials business, we are involved in all aspects of supply, from planting the trees that provide the wood used to make building materials, through product development, fabrication and trading, right down to the distribution and sale of materials. In this sector, we also play a mediating role in the supply of construction facilities, equipment and materials not only for development projects conducted by the ITOCHU Group but also in various other types of projects both in Japan and overseas, and we are working to strengthen the ITOCHU Group’s value chain in the building materials business.
