Value Chain of the Housing and Construction Business

Sales/Product Development

Housings at the Sumitomo Forestry Group are mostly custom-built detached housing designed to each customer's individual home specifications. We listen carefully to the requests of our customers to provide the best lifestyle based on their wishes.

The Sumitomo Forestry Group pursues better housing performance from a wide range of perspectives, including earthquake resistance, fireproofing, insulation efficiency and universal design in product development.


The Sumitomo Forestry Group provides long-lasting, high-quality housing by fully taking into account safety, durability and the environmental impact at the design stage. We have maintained our ratio of houses certified as Excellent Long-term Housing for new custom-built houses through development such as Net Zero Energy Houses (ZEH) and the BF Method up until now.

Materials Procurement

The Housing and Construction Business procures a wide range of materials from timber and concrete to kitchens and toilets. Promoting fair and responsible initiatives for these procurement activities are the social responsibility of the Group.


Sumitomo Forestry considers safety while working carefully and efficiently to complete the construction on time for the customers. Therefore, we are building a system to ensure our policies and initiatives are carried out on-site by the construction contractors through thorough implementation of safety training and environmental education.

After-Sales Support

The Sumitomo Forestry Group aims to provide housing residents can live in over the long term by pouring its strength into after-sales support. Therefore, we conduct customer satisfaction surveys and have set up a call center. Sumitomo Forestry has been conducting free periodic inspections for 30 years after homes are delivered to their owners, and thereafter provides paid maintenance services according to maintenance plans. Owners can also extend the building warranty every 10 years to receive these free periodic inspections for up to 60 years.

Promote Further Integration of Business Operations and ESG Initiatives in the Housing and Construction Business

The Housing and Construction Business provides homes and services to give customers long-lasting peace of mind and safety in life while being environmentally sound in each process from development and design through construction, the use of sustainable timber and construction materials and the execution of construction on safe work sites as important issues.

One of the areas which we can contribute the most in reducing environmental impact is the reduction of greenhouse gases emissions from housings that people live in. Sumitomo Forestry sets ZEH order quotas and other targets for environmentally conscious products. Recommendations of ZEH housing while tailoring energy saving, energy generation and resilience function specifications to customer needs reduces the energy consumption of each household.

The Sumitomo Forestry Group will contribute to the realization of a prosperous and sustainable society from home building and popularization of non-residential wooden constructions to townscapes redevelopment.
