Supply Chain Overview Strategies for establishing a stable supply chain for developing a structural composite lumber (SCL) market in Japan This report works to identify the elements required to establish steady demand for the utilisation of current wood stock in Japan with the ambition to create a Stable Supply System of Wood to benefit all involved. The main objective is to propose a strategy for structural composite lumber (SCL) stake holders and propose a reasonable collaborative relationship with a construction company with the end goal of developing the SCL market in Japan. The proposed supply chain focuses on the implementation of new wood engineering technology, specifically Cross laminated Timber (CLT) and its application in prefabricated housing for driving demand in the industry. This report has been structured to go through the main issues and companies involved from the felling of a tree to the construction of a wooden house (figure 2‐3).

Supply Chain improvement
The current state of Japan’s wood supply chain has improved from previous years but still maintains issues with profitability, co‐ordination and demand creation.1 Three main points for improvement will be covered when analysing the entities involved in the supply: 1. Creating a steady demand for timber for housing and timber product export in order to establish a stable supply system of wood not susceptible to decline. 2. The process of facilitating cooperation and coordination between stakeholders, from forest owners, national forest offices, forest management programs, loggers, lumber mills, wood product factories and house makers. 3. Raising people’s awareness of the importance of forestry and wood products in relation to culture, environment and economy. 1 Forest Agency.

Chapter I Stable Supply system of Wood Identification of Companies/individuals/associations involved The entities involved in the supply chain can be broken down into categories from raw material to end product: 1. 2. 3. 4. 5.
Timber Sourcing and Management Private Forest owners National forest associations Management of forestry contractors Government Incentives Ministry of Agriculture, Forestry and Fisheries (MAFF) Ministry of Land, Infrastructure, Transport and Tourism (MLIT) Infrastructure, transport and equipment Logging Transport Rationalization of Timber Distribution Wood processing and Products Round wood lumber yards Other wood products SCL Factories (e.g. meiken kogyo) Prefabricated wooden housing House builders (e.g. Sekisui Heim)
The export focus is on plywood and domestic round wood (figure 4). The new proposed supply chain places an emphasis on utilising domestic forest as a source and increasing advanced wood products including laminated lumber and prefabricated homes/components (figure 5). The resulting effect would be one that creates a steady demand needed to maintain work for all entities along the supply chain. Exporting engineered products is more profitable than exporting raw materials and a more expansive supply chain provides more skilled job opportunities for the Japanese youth. As well as economic benefits, domestic wood supply would help maintain healthy forests in Japan which cover almost 70% Japan.2

Chapter II Timber Sourcing and Management With 68.5% of Japan covered with forests3, there is no lack of raw construction material. Growth of forest stock is not a problem (figure 6), however the geography and the ownership of these forests are. These two complications result in issues relating to reaching the steeply growing forests and to co‐ordinating both privately and nationally owned forests.

Private Forest Ownership As seen from the data collated by the Ministry of agriculture, Forestry and Fisheries, Privately owned forests make up almost 60% of the total (Figure 7). With almost double the amount of nationally owned forests, private ownership needs special attention in regards to addressing their locations, boundaries, management and potential in the market. What exasperates the situation more is that of the 14,440 hectors comprising the private forests, approximately 90% of forest owners have less than 10 hectares of forest.4 This creates a tremendous amount of forest boundaries and co‐ordination issues. MAFF is currently tackling this issue with three methods which need enforcement5: Mandatory forest notification system: The “Forest Act” in 2011 announced a notification system that necessitates new forest owners to register with the local authorities, with the additional intention to promote the sharing of information within relevant forestry organisations. Availability of Forest Management Planners: Private forests are becoming increasingly neglected with the age of forest owners rising and owners moving away from the forest location. The government have introduced Forest Management Planners who can coordinates forest owners and unite forestry practices. Promotion of production management for forestry contractors: To increase the utilisation of wood stock and encourage using the forest for profit, management schemes are being offered to forestry contractors which many private owners intrust the management of their forests.
National Forest Association The second largest portion of forest ownership belongs to the National forest association with 30% of the total forest area.6 These National Forests not only contribute to round wood production but play vital roles contributing to the country’s ecological functions of forests, including watershed, land and biodiversity conservation. All of Japan’s need to be consolidated in order to establish a forestry practice which balances the country’s need for raw material and environmental welfare.

Forestry Stock 4.9 billion m3 of forest stock is available in Japan and over 51% of Japanese forests, naturally occurring and especially those forests planted after World War II have reached the matured harvesting age (figure 9). Around the age of 50 years, trees are matured (figure 11), whereby afterwards, growth is reduced and the aging forests can risk a variety of environmental issues such as fires, landslides and soil erosion7. Now is the ideal time of selective logging. Figure 9: Growing forest stock

Environmental Benefits Forests and their regeneration through thinning, play a multifunctional role in contributing to people’s lives as well as national economy. In relations to the environment and people’s wellbeing, forests are essential for activities such as water resource and soil, landslide and fire prevention, health preservation and recreation, culture, biodiversity and global environment conservation. Planned thinning of forests (figure 12) and felling of mature trees not only provides raw material for construction demands but is essential for forest health.
Figure 12: Forest Management Cycle A few of the benefits of thinning include the encouragement of new growth and strong root development of remaining trees which allows the forest to become more weather‐resistant from natural elements such as strong winds and heavy rain. 8 Gaps in forest canopies allows sunlight to reach deeper into the forest, providing opportunity for lush greenery to grow below which in turn prevents soil erosion. This rich environment attracts encourages of various plants and attracts animals to live and breed, resulting in greater biodiversity. 8 Forest Agency.

Chapter III Government Incentives
Ministry of Forestry Plan to Create Dynamism through Agriculture, Forestry, and Fisheries and Local Communities In December 2013 the Government established a plan for “creating new wood demand”9. The ideas promoted in this plan align to ideas explored in this report’s proposal for a new improved distribution strategy. The key three points outlined in the plan were: • Promotion of new engineered wood products and technologies such as Cross Laminated Timber. • Update guides, regulations and plans to develop cities with more wood construction. • Utilise the country’s rich supplies of natural resources and new technologies
Roadmap for Disseminating CLT The following year in November 2014, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) publicized the Roadmap for Disseminating CLT. The document laid out the steps and schedule in relation to popularising the use/ production of CLT with an ultimate goal by 2024 of pushing the ‘annual production capacity to 500,000 m3 of CLT.’ 10 Figure 13: CLT Road Map 9

The MLIT is particularly encouraging the use of sugi and hinoki for CLT panels11 through the roadmap, promotions and a number of incentives: Compile data on the properties of CLT and develop CLT‐related building standards by FY2016 (which has been already completed) Increase construction of exemplar CLT projects and wood use in commercial and public buildings with a 6% share of buildings up to 4 stories Construct new Laminated lumber mills providing subsidies to offset costs up to 50% of the investment Set a target of 500,000 m3 CLT production capacity by 2024 Overall aim to reduce CLT production cost by over 50% from ¥150,000m3 to ¥70,000m3 by increasing demand and production Yearly targets to increase CLT production capacity by 50,000 m3 As seen through these plans, publications and incentives, the Japanese government are committed to advancing wood culture and associated technology. What is required now is co‐ordination and awareness of these situations.

Chapter IV Infrastructure and transport Introduction of Efficient Log Production System With over 70% of Japan’s area being mountainous12, being able to cut and move these steeply located trees efficiently is an essential part for making forestry profitable. Logging is positioned at the forefront of the supply chain, emphasising its importance. The forestry agency is currently tackling this issue through two methods13:
1. Developing second‐generation cable‐yarding forestry machines which essentially utilise cables to vertically move logs in steep forest sites. 2. Training people and equipping them with techniques to operate the newly developed cable‐yarding devices.
Development of Forestry Road Network With both national and private forests widely distributed across the country and along mountainous regions, developing a road network which can reach all these areas is crucial for the supply chain. With no transport link, the idea of commercialising these small scattered forests becomes unfeasible and they will be left unused. A well planned out road network the key infrastructural component to enable efficient forestry practices and distribution. Currently the Forestry Agency is working on developing three types of forest road14: 1. General traffic forest roads 2. Heavy truck and forestry exclusive roads 3. Forestry machinery and forestry operation roads This approach not only develops infrastructure for the wood related industries but allows access for the public to reach more remote areas which can encourage people to make a living in rural areas instead of moving to the urban cities.

Chapter V Wood processing and Products Lumber Production The percentage of domestic forests used in the raw material inputs for lumber mills is over 70% (Figure 14). If this strategy keeps momentum, it could be possible to see complete self‐ sufficiency in raw food supply in the near future, acting in line with the proposed supply chain strategy.
Figure 14: Material inputs for lumber production
Timber Products Wood supply self‐sufficiency (including raw timber and wood products) was 31.2% in 2014 which was a benchmark of Japanese wood supply since it was the first time to exceed 30% in 26 years15. Since then, the ratio has been rising in recent years as domestic stock and demands are increasing. The reason behind this are that planted forests are getting mature and use of domestic wood for plywood has become popularised (the second largest wood export behind round wood Figure 16). The plywood industry has been flourishing in recent years and uses more domestic timber than every recorded, combined with improved processing technology. As forest co‐ordination is gradually improving, recently, large processing mills are constructed closer to available forests in the vicinity (Figure 15). With the effectiveness of the supply chain being proven, it is possible to do the same with CLT. Over recent years MAFF has been trying to emphasise that point that ‘In order to strengthen the competitiveness of the wood products industry, it needs to supply wood products in a way that it meets consumers’ and demanders’ requirements in terms of quality, quantity and time of delivery, while securing stable procurement of roundwood.’16 The culture, associated costs and construction standards linked with wood needs to rise over well‐established materials such as concrete. 15

Figure 16: Japan’s wood exports The total value of wood exports reach 22.9 billion yen in 2015 which is almost a 314% increase in fourteen years (figure 16). Round wood, sawn wood and plywood dominate this market, however to further increase export and profit; exporting more processed wood products in key. Potential target countries could include China and South Korea. With dramatic projected increases in GDP (Nominal) Rankings for 2030 (1st and 7th world wide ranking respectively)17 and sharing cultural similarities in their architecture, these countries have great potential. Exporting laminated wood products and wooden housing components to these countries which have already popularised views of Japanese wood architecture, is one strategy. MAFF already has taken several steps in starting initiatives to promote exports of wood through exhibiting wooden houses, products and components at housing exhibitions abroad. In addition to this, the government is participating in the revision work of Chinese wooden building standards as a platform to introduce Japanese wood products into the market.18 This would however require further opening of foreign branches for distributing and promoting wood products. Figure 15: Newly constructed large mills
The supply chain proposed in this report is targeting 100% domestically supplied wood for laminated lumber mills. The share of domestic wood inputted for laminated lumber mills has been rising, but it still a low figure at 16% in 2014. Plywood production is leading the way with utilising domestic wood supply for its factories with the supply being 70% in 2014. 19 However when the figures for imported plywood are included in the sum, the domestic share of wood is reduced to 30% (figure 16). There is still a high reliance on foreign wood products. 17

Figure 17: Major wood products
Figure 18: Newest CLT wood product
The newest addition to the wood products is Cross Laminated Timber (CLT‐Figure 18). CLT is similar to plywood in terms of layers of wood being glued together in odd numbers and at alternating at right angles. The main difference is that CLT uses dimensional timber rather than thin veneers in its layers and the panel thickness has a much greater range from 50mm to 500mm panels.20 In 2015 there were six laminated lumber factories operating in Japan. Three of them currently have to converted/ adapted for CLT production.21 If demand for this product can be increased, then other factories can be built or converted for CLT production near maturing forests.

Chapter VI Prefabricated wooden housing Wood in Housing In reference to the use of standard dimensional timber and plywood, there is still a large demand for these products in the construction of new dwellings. Almost 40% of wood demand and over 50% of domestic wood demand are for building construction.22 Timber frame construction is still the cheapest form of construction in Japan, resulting in half of new housing starts in Japan created from wood. Even though new house builds are decreasing, the utilisation of wood as a building material is increasing. The table below shows a 10% increase in wooden construction from 2010 to 2015 (Figure 20). The streamlining process of using standard wooden construction in housing has drastically reduced cost and time, resulting in its popularity. If this popularity could be transferred to laminated wood products, the market could greatly expand.

From the 1970s, wood prices declined while forest management costs increased, crippling profitability of forestry causing forests to go neglected and unused (Figure 21). To meet wood demand, the volume of imported wood increased, peaking in 1996. The volume of imported wood products overtook that of imported round wood in 1987. Previous incentives and government plans explain in previous chapters have resulted in positive effects with around a 10% rise in the share of wooden houses from 2002 (figure 22). Similarly imports, particularly of round wood are being gradually reduced.
Prefabricated Homes From the 1970s to the modern day, demand and construction of prefabricated homes have remained stable relative to other detached houses and dwelling units (Figure 23). There has been a 9% increase in prefabricated homes from 2010‐2015 (figure 20). Proven a stable industry, the prefabricated housing market makes a suitable target for implementing CLT construction to increase its demand. There are five major reputable pre‐fab housing builders (Figure 24), however Sekisui Heim has the largest production of modular housing rather than panelized housing. A modular construction system has more potential benefits in relation to finished product quality and simple implementation of CLT for the modules. However, in the future, CLT could be used by other companies for panelized construction methods too with the benefits that it is easy to transport (especially abroad) due to the flat‐ pack style approach.
Figure 23: Construction type and housing built in Japan 1970‐2002
Figure 24: Largest Japanese house builders
Sekisui Heim has been selected as a possible exemplar company to begin the application of CLT into their prefabricated homes. The main reasons for this are that the wooden modular production utilised by Sekisui Heim could be adapted to assemble CLT modular wooden units instead. This would greatly reduce startup costs and allow for a much quicker implementation of new design and construction.
17
Figure 25: Types of prefabrication in the Japanese prefab housing industry
Sekisui heim currently has two different models for modular design. One utilises a steel frame, while the other, a wood‐frame. (Figure 25) CLT suits modular construction because the panels are already large and strong enough to make individual walls of the modular without any intermediate connections. Modular housing also allows for airtight and stronger construction in factory, providing greater quality housing (Figure 26‐27).
Figure 26: A sample modular unit created from CLT
Figure 27: Illustration of the layers comprising a CLT panel
18
Prefab capable factories Sekisui Heim claims that nearly 80% of housing components used for building a house can be assembled at their factory.23 With its current eight factories in Japan producing wood‐ and/or steel‐frame modular homes they process expert knowledge on modular production and have one of the highest mechanised assembly lines in Japan.
Of the factories which Sekisui heim possess, five have wooden modular production facilities: Tohoku Sekisui Heim Industrial Co., Ltd. Kanto Sekisui Heim Industrial Co., Ltd. Chubu Sekisui Heim Industrial Co., Ltd. Medium Shikoku Sekisui Heim Industrial Co., Ltd. Kyushu Sekisui Heim Industrial Co., Ltd.
Figure 28 shows a summary of a typical production line for producing steel modular units by Sekisui Heim. A very similar production approach can be taken when utisling CLT panels instead of a framing method. In fact, the production line would be shorter as the wall panels need less finishing and openings can be quickly pre‐cut. Figure 28: Factory production line of a Sekisui modular steel home When these factories are aligned with the location of CLT producing facilities, a potential starting point for the supply chain becomes obvious. The meiken kogyo CLT factory and the Sekisui Hemi Shikoku modular producing factory are in close proximity (Figure 30). Therefore, with improved forestry co‐ordination, management and utilisation, local forests can be utilised in the Shikoku region and then processed in the neighbouring factories. This is just one potential supply link, but it shows the opportunity for an efficient process. 23

Marketing Strategy Japanese affinity with wood and the culture surrounding its use, is still apparent and alive in modern day Japan. By appealing to Japanese tradition while adhering to modern day fireproofing/ earthquake resistance regulations with modern lifestyle luxuries, an effective branding strategy can be formulated. Comparing the images of an edo‐period, traditional town house to a modern day, prefabricated CLT house produced in Austria by Bruno Klomfar, one could see the potential of merging a design into a Japanese style CLT house.
Figure 31‐32: Interior and exterior of traditional town house in Nara
Figure 33‐34: Interior and exterior of modern prefab CLT house in Austria
Figure 35: Modern and traditional mixed style house by architecture Kengo Kuma 21
Target Market Generally in Japan, pre‐fabricated housing targets the upper‐middle, upper wage classes. A prefab house constructed by Sekisui Heim is about ‘16% higher than conventional post and beam traditional housing’.24 However, what is offered in return is supreme quality, service, convenience and customability. A survey conducted in 2008 shows how reliability and superior product quality and performance are the highest motivational factors for purchasing such as house (Figure 36). In this sense, although CLT as a product is more expensive that standard wood frame, the superiority of the product and the marketing from a reputable company such as Sekisui Heim is a plausible strategy.
Figure 36: Japanese Buyer’s motivation for buying prefabricated housing
Prefabrication approach Using the facts provided in the survey, the solid wood modules would be marketed as traditional style Japanese home with the additional benefits of: • Structural strength • Durability • Resource saving and generating • Amenities • Customization and design

Summary Benefits of a Stable Supply System of Wood Below comes an elaboration on the benefits of the suggested wood supply chain, which are important in relation to convincing, stakeholders, government committees and the public in the need to drive these changes.
Figure 37: Proposal for supply chain targeting the production of laminated lumber for prefabricated housing It has a threefold impact on the demand side, supply side and environmentally. Figure illustrates a focus on local raw material use and high end‐ engineered wood for high end housing products to be used domestically and exported. The benefits affect the following entities: 1. Lumber mills It provides lumber mills in the demand side, with opportunities to procure timbers in a stable amount with specific requirements, assisting the optimized operation and cost reduction of the selected mills. 2. Forest owners and log producers Such a system also helps forest owners and log producers as supply side to secure stable clients contributing to their stable management.
23
3. Environmental benefits Necessitates the maintenance and replantation of forests, reduces natural disaster risk and promotes a healthy landscape for long‐term operation of the supply chain. 4. Building contractors and housing makers Building contractors and housing makers also benefit from procuring building materials, within a specified period and at a specified cost. They have potential new marketing strategy and new generation housing model with export potential. 5. Public Public can celebrate their culture of wood without sacrificing modern luxuries of homes and enjoy a superior home.
Figure 38: Placement of prefabricated hotel room modules for a hotel in Austria
Figure 39: Exposed wooden interior of the modular hotel room
Figures 38‐39 show a precedence for CLT modular construction for a hotel in Austria. The Alpen hotel Ammerwald by Oskar Leo kaufmann and Albert Ruf is a 16 meter tall building stacked with 96 units all constructed from CLT.25 The speed and quality of manufacture is one to be admired. On the factory line 96 units were constructed in only 31 days. This equates to a rate of about 3 a day. If government associations and ministries such as MAFF continue to promote an improved and updated wood supply chain, then such projects can be realised in Japan with great benefits to the country.
