Basic Policy

Sumitomo Forestry has been engaging in forest management for more than 320 years. In addition, we create living spaces which take advantage of wood through our expertise in the various properties of wood worldwide. By dramatically furthering wide-ranging experience, knowledge and technology, we propose wider use of wood and timber in non-residential buildings, such as medium to large-scale construction. Sumitomo Forestry is promoting MOCCA (Timber Solutions) Business in which proposes wider use of wood in non-residential buildings such as industrial and public facilities.

In 2009, the Japanese Government formulated the Forest and Forestry Basic Plan as a forest and forestry recovery policy. This plan sets a timber self-sufficiency rate of at least 50% by 2025 as an ideal approach and positions the expansion of wood use as national policy, including the Public Buildings Wood Use Promotion Act enacted on October 1, 2010.

Through the MOCCA (Timber Solutions) Business, Sumitomo Forestry will bring out the excellence of wood and cultivate new value and potential such as warmth, tranquility, and comfort in addition to aligning the passion of companies, individuals, countries, municipalities and others to expand the transition to wood as a new building method worldwide. This is the mission Sumitomo Forestry must fulfill as a company involved with wood since its founding.

Using Wood in Buildings to Help Transform Work Styles- Kokubunji Head Office Building of Flavor Life Co. Ltd.

Flavor Life Co., Ltd., which has its head office in Kokubunji City, Tokyo, provides aroma products that incorporate blessing of nature into daily life. It is a company that creates lifestyles with fragrance and smiles through aromatherapy.

As a company that handles products made of natural materials, wish for a building that used natural materials it is a matter of course to wish above all else, the company wanted an environment in which employees could work comfortably. A wooden-hybrid building was realized in July 2017 with the passion of the proprietor.

Time spent in a workplace is no fleeting moment for the working people. It is surely fair to say that bringing comfort and coziness to a living space in which so much time is spent to be an important element of in promoting work style reform.

The effects of a peaceful workplace incorporating wood, in which employees say they can relax while working, and communicate more with coworkers, has begun to be reflected in employee satisfaction levels and productivity of work.

This wooden-hybrid building has a steel frame structure for the first three floors and a wooden-hybrid structure for fourth through seventh floors. Its most distinctive characteristic is its use of hybrid laminated engineered wood which the steel frame is completely covered in wood. Featuring a combination of the soft texture of wood and the strength of steel, it enables the wood to protect the steel from heat as a fire-resistant coating, contributing to disseminate incorporation of wood as a material for buildings.

The aim of Sumitomo Forestry is to create vistas lined with buildings that provide a sense of the warmth of wood in cities, where contact with wood is rare. We apply our knowledge and experience in using wood to propose new ways of doing so.

* This project was selected as a pilot program for sustainable buildings (wood type) of Ministry of Land, Infrastructure and Transport in fiscal 2015.

Participating in Building Energy-efficient, Environmentally-friendly Convenience Stores

Sumitomo Forestry designed and built the energy-efficient, environmentally-friendly Numata Interchange Family Mart convenience store which opened in Numata City, Gunma in December 2019. This store was a pilot test that aimed to save energy by combining the strengths of various environmentally-friendly products from participating companies.

Sumitomo Forestry proposed and employed Cross Laminated Timber (CLT) materials made from domestic wood for the walls of the structural framework. Use of Sumitomo Forestry’s original S-100 coating material (powerful water repellent silicone coating) on an exposed timber* style even improved weather resistance. Nelson Pine Industries Ltd. (NPIL), a Sumitomo Forestry subsidiary in New Zealand, even took charge of the beam construction by manufacturing the Laminated Veneer Lumber (LVL) that was used. As of May 2020, our Group has completed a total of 204 stores by proposing this type of wood construction.

Trees continue to stabilize CO2 as carbon even after they are turned into products. Wood structures help reduce CO2 emitted by these stores throughout the entire life cycle from material procurement to construction, renovation, repair, demolition, and disposal better than light gauge steel used for columns and beams.

We also took advantage of a grant for the CLT materials used in this store through an individual proof-of-concept project for expanding the use of JAS structural materials, which is a Forestry Agency subsidy program. Sumitomo Forestry will promote further use of wood by providing total solutions from the procurement and supply of materials to the construction.

Toward the Future -Aiming for the Timberized Eco Cities with W350 Plan-

Sumitomo Forestry announced its W350 Plan in February 2018. The W350 plan is a research and technological development roadmap aiming to build a 350-meter-tall wooden high-rise building in 2041, which will mark the 350th year since foundation of business in 1961, in preparing to create Timberized Eco Cities. The plan is intended to develop future technologies that contribute to people's lives, society and the global environment, including building construction methods, environmental technologies, wood for building materials and resources.

The new three-story wooden research building completed in October 2019 at the Tsukuba Research Institute will help further this plan as a research and development base.

Toward Realizing the W350 Plan

Managed mainly by our research and development center, Tsukuba Research Institute, the W350 Research and Technological Development Plan is a roadmap for future technologies; to develop building construction methods, environmental technologies, wood for building materials and resources. This roadmap will expand the possibilities of wooden structures.

This plan of creating Timberized Eco Cities centered on wooden high-rise buildings will revitalize the forestry industry with increased demand of timber and mitigate climate change with increased fixation of CO2; in essence, Sumitomo Forestry will contribute to invigorate the community and to realize coexistence with the global environment.

Building outline:

  • Height - 350m, Number of floors above ground - 70 floors
  • Building use: Stores, offices, hotels, residences
  • Building area: 6,500m²
  • Design collaboration: Nikken Sekkei Ltd.
  • Architectural area: 455,000m² (6,500m² × 70 floors)
  • Amount of timber used: 185,000m³
  • Structure: Wood and steel hybrid structure (Internally, pure wooden structure)

New Research Building of the Tsukuba Research Institute, Which will Serve as the Research Base for the W350 Plan

It has been 29 years since Tsukuba Research Institute was established. The deterioration of the main research building and increase in staff have become issues needing to be addressed. The new research building completed in October 2019 adopts new Post-tensioning*1 technology related to the wooden structures. Other technologies used in this building will also form foundation for the W350 Plan. Energy saving technology and renewable energy will also be used with a view of achieving a zero energy building (ZEB).

The new research building is a three-story building with a floor area of 2,532.67m². The exposed beams, pillars, and wall structure has been designed using the semi-fireproofing technique. Full building evacuation safety verification [Route C (Minister's certification)]*2 makes it possible to reduce restrictions on wooden interiors so that spaces with the qualities of wood can be presented. The building greatly reduces CO2 emissions by installing solar panels on the roof and adopting absorption water chiller-heaters fired using wood pellets. With roofs, balconies and exterior walls used as areas to test greening, the research and development of green technologies for non-residential wooden architectural structures will be conducted while office space will be used for verifications such as green layouts that seek to improve intellectual productivity.

This facility has been accepted as a pilot program for sustainable buildings (wood type) in fiscal 2017 promoted by Ministry of Land, Infrastructure, Transport and Tourism. This includes an office for housing 140 persons and a gallery that provides information about timber.

With the new research building positioned as the cornerstone of the W350 Plan, we also began a construction plan for a six-to eight-story wooden building (20m to 30m tall) as the next actual step forward. This plan has been named “W30” and is currently under way.

*1 Technology where high-strength steel poles and wire ropes running through load-bearing members are tensioned to increase the fixation of position between members.

*2 A method for verifying safety performance where everyone within a building is able to evacuate safely to the ground level given a pre-determined fire scenario. If safety can be confirmed, some of the regulations of the Building Standards Act of the Japanese government are eased, enabling greater freedom of design, such as exposing wood structural members to view. Route C designation requires certification by the Minister of Land, Infrastructure, Transport and Tourism, but since evacuation safety performance is confirmed using sophisticated calculation methods not stipulated by the notice, it allows for the highest level of design freedom.
