Mr. Tomohisa Iida
Kurume-shi Government Office3,560 kWThe Miyanojin “Manabino” Biotope was completed in April 2016 at Miyanojin Clean
Center in Kurume. We created the facility’s basic design with the goal of having it becomea new symbol of Kurume and serve as a place where people could learn about the environment and spread what they learn while coexisting with the area’s scenic natural landscapeand as a place where people could learn about the plant and animal life that inhabits thecommunity. We built a space with water, plant life, and soil to foster a variety of plant andanimal species that live and reproduce in the basin’s rivers, waterways, and surroundingareas. Going forward, we will work with Kurume High Trust to ensure that the facility willserve as a place where people can learn about the natural environment so that Kurume’s
exceptional environment can be passed down to the next generation by using the biotope
to host classes and events.
We held an experience-based learning event entitled “Mission: Find Aquatic Life” inAugust as the first environmental learning activity we proposed in FY2016. During thatevent, we caught fish living in rivers in the Chikugo River water system, released them into
the biotope, explained the ecology of the captured fish, and considered the implications
together with participants. The second activity took the form of a parent-child class
entitled “Learning How Fireflies Live” in March, where we explained that thinking about
how fireflies live means thinking about the local environment. Going forward, we will help
author the Miyanojin Biotope Newspaper, which is published by Kurume High Trust eachseason, by proposing new lifestyles to help ensure Kurume will have a rich future while
communicating information about plant and animal life as well as seasons from theMiyanojin “Manabino” Biotope.

TAKUMA CSR REPORT 2017

Feature: Strivingto Coexist withLocal Communities

The Kurume Northern Municipal Solid Waste Treatment Plant Development and Operation Project is being implemented asa DBO-style program that integrates facility design, construction, and operation in order to facilitate the proper processing ofmunicipal solid waste from the Kurume City. Under the project, Takuma Co., Ltd. was responsible for designing andconstructing the plant building, and Kurume High Trust Co., Ltd. took over operation of the plant following its completion inJune 2016.
The company’s goals in operating the facility include giving top priority to safe and stable operation, working to reduce its
environmental impact, ensuring that area residents feel secure living close to the plant, and utilizing it as a place wherepeople can gather to learn about the environment and related topics.
The facility has also been designed to help form a low-carbon society
and realize a recycling-oriented society. The incineration facility is designedto utilize energy effectively by using surplus heat from incinerated waste
to generate electricity and selling surplus power remaining after plant
operation to power companies. Metals in the crushing and sorting
facility’s output stream are sold and recycled, while incineration ash isused effectively as a raw material in the production of cement.

The Kurume City built Miyanojin Clean Center, its second municipal solid waste intermediate treatment facility, so that it could promote the development of a recycling-basedsociety and carry out safe, stable waste processing over the long term.
With an incineration facility, crushing and sorting facility, and recycling facility as well as
the Environment Interchange Plaza, which is designed to serve as a place for environmental
awareness-raising and learning, Miyanojin Clean Center will not only process and recycle
waste, but also facilitate learning about the environmental field in general while revitalizing
the local community and creating a sense of excitement and activity in the surroundingarea by fostering social interaction through citizens’ activities.
To achieve these goals, I believe that it will be important for the facility to earn the trustof city residents so that it becomes a familiar presence to them and to contribute to thecommunity. We expect Kurume High Trust to pursue an active program of community
initiatives, for example by creating a sense of excitement by hosting environmental
awareness-raising events and exhibits that take advantage of the facility and cooperatingwith events conceived to revitalize the local community even as it gives top priority toreducing environmental impact and operating the facility in a safe and stable manner.

In the area around Clean Park Hokutan, there were a series of satoyama sites (including
terraced fields, rice paddies, bamboo groves, and forests) that had not been maintained over along period of time. In order to protect and restore these areas while utilizing them as places forlearning about coexistence with nature, studying the importance of resources and the environment, and gathering to foster rich sensibility, we took advantage of the opening of Clean Park
Hokutan to develop a plan for restoring these satoyama spaces, and we have offered assistanceto environmental learning projects that utilize them after the facility began operation.
Starting with information about satoyama spaces that we provided during the facility’s opening event in August 2016, we have planned and orchestrated a variety of events at which a large
number of area residents have participated and enjoyed themselves, including an acorn craft
session at which people made tops and traditional balancing toys with acorns that had beengathered in the satoyama; a parent-child soba-making and rice cake-making party where people
could experience those traditional techniques, which have been passed down in the community;
and a spring plant gathering where participants viewed and tasted flowers and mountainvegetables that can be found in satoyama spaces in spring. Going forward, we will continue tooffer operational assistance to ensure that Clean Park Hokutan can revitalize nature in this new era
and encourage regional interaction while fostering these satoyama spaces together with local
residents, for example by maintaining bamboo groves and forests and managing cultivation fields.

Clean Park Hokutan was built as a DBO project under the provisions of the Act on Promotion of Private Finance Initiatives
with the goal of protecting the living environment in the Hokutan region, improving public health, and moving away from asocial paradigm founded on mass production, mass consumption, and mass disposal to advance the 5Rs of waste (refuse,reduce, reuse, repair, and recycle) in a comprehensive manner by facilitating the proper processing waste generated day inand day out by the city of Toyooka and the towns of Kami and Shin’onsen. Designed and built by the TakumaKabumoto-Kawami-Nishiyama Designated Construction Joint Venture, the facility was completed and began operation in July2016.
In addition to ensuring safety and inspiring peace of mind in the future on the part of area residents by reducing thecommunity’s environmental impact, the facility is dedicated to serving as a designated evacuation center in the event of adisaster and to functioning effectively as an area center of environmental learning and awareness-raising.
The facility also combats global warming through effective use of energy by using surplus heat produced when theincineration facility burns waste to generate electricity and then selling the surplus power that remains after facility use to apower company (Takuma Energy Co., Ltd.) under Japan’s renewable energy feed-in-tariff program. In addition, generated
power is supplied to public facilities such as elementary and middle schools in Clean Park Hokutan’s member towns and cityin the spirit of “local production for local consumption.” The crushing and sorting facility also helps advance the 5Rs byrecycling processed materials.

The process leading to this project’s successful completion in July 2016 involved many twists
and turns over more than 18 years since the Hokutan Regional Waste Processing Plan wasformulated in December 1998. This success despite numerous challenges—for example, changes
in the height of the foundation during the earthwork phase and a reassessment of the project
design—due to the project’s reliance on a financing plan that utilized a jointly issued bond anddeadlines that were extremely demanding was made possible by the tireless efforts of thepartners in the Takuma Group Joint Venture, for which I am deeply grateful. When our association formulated the basic policies that would guide the construction of the facility, we asked
that it protect and revitalize the surrounding environment, that it foster coexistence and mutual
prosperity with nature, and that it serve as a dynamic and exciting place where people can learn
about the importance of resources and the environment through waste and enjoy interaction
with their fellow residents. We are pleased that the joint venture was able to construct a facility
that conforms to the construction policies that were put in place by our association.
One year has passed since Clean Park Hokutan began processing waste as part of its trial
operation phase in April 2016. Maintaining equipment reliability and operational stability is anextremely important part of continuing to operate the facility in a safe and stable mannergoing forward, and despite various issues, Hokutan High Trust is working hard to do just that.
We trust that it will continue to work hard to resolve the remaining issues. The facility began
hosting tours and environmental learning events in September 2016, and by March 2017 it
had hosted 1,373 visitors at a total of 51 tours and events. Hokutan High Trust has provided
assistance with planning events and explaining the facility to visitors, and the feedback that ourassociation has received through surveys and other means indicates that visitors are pleased
with the polite and accommodating reception they received. Going forward, we fully expect
Hokutan High Trust to operate the facility in a safe, secure, and reliable manner over the20-year period ending in July 2036.

the Lake Administrative Affairs Association and its member cities and town.
I believe that the most important aspect of these operations over the long term iscoexistence with the local communities, which is also a priority of the Association and its
member cities and town.
Although intermediate processing facilities have not enjoyed a particularly favorable imageto date, we look forward to striving daily to operate, maintain, and manage the facility in a waythat will endear it to everyone in the local communities. In doing so, our goal will be to involve
everyone in the process of “raising” eco-Poppo while visualizing the status of facility operations
and disseminating information in an accessible manner (via digital displays, the facility’swebsite, etc.), disclosing information about those operations to local communities by holding
participatory events for residents (including operational briefings and facility tours), and actively

Suwako Koshu Clean Center was constructed as a DBO project with the goal of facilitating the smooth implementation ofmeasures related to waste processing and the development of a recycling-based society through the joint, regional processing of waste by the cities of Okaya and Suwa and the town of Shimosuwa, all of which lie in the lakeside district. The
Takuma-Okayagumi Designated Construction Joint Venture designed and constructed the facility, which began operation inDecember 2016.
To operate the facility in a way that achieves the goals of safeguarding nature,
educating residents, and connecting communities, Suwako High Trust is dedicatedboth to operating the facility in a safe and environmentally friendly manner so as toinspire peace of mind among residents and to coexisting with local communities
over the long term as a facility of environmental creativity where large numbers ofpeople gather.
In addition, the facility is helping to form a recycling-based society as part of theTakuma Group by recovering as much heat from waste as possible and converting it
efficiently into electricity and then selling surplus power remaining after facility useto Takuma Energy Co., Ltd. under Japan’s renewable energy feed-in-tariff program.

The Suwako Koshu Clean Center was successfully completed in December 2016 following aseries of twists and turns as the embodiment of the Lakeside District Waste Processing Basic
Plan that was formulated in 2005. The project’s goal is to jointly process waste from thelakeside district that includes the cities of Okaya and Suwa and the town of Shimosuwa on theshores of Suwa Lake, which is located in roughly the center of Nagano Prefecture. Thanks to thetireless work and constant effort of Takuma, we were able to overcome the many challenges
and unexpected problems that continued to arise until the project was completed. I’d like toexpress our deep gratitude to all of your workers, along with my respect for their enthusiasm
and commitment. The completed facility provides functionality worthy of being calledstate-of-the-art, and it is also equipped to disseminate information as a symbol ofenvironmental protection. In particular, the center will help form a recycling-based society byreducing CO2 emissions through the generation of electricity from heat, which it accomplishes
at an efficiency of close to 20%, highlighting its performance. Once the electricity has beenused locally, surplus power is sold. Concerning the concentration of exhaust gases, an area ofhigh interest to local residents, we required the facility to generate emissions that do not exceed
legal levels, but your company submitted guaranteed levels that are even lower than thoselevels as part of its focus in operation and management of reducing the facility’s impact on theenvironment of the surrounding area. Your employees have served as volunteers at a marathon
held near the facility, and they’ve cooperated with cleanup and other activities. You’ve also
earned trust by treating customers who bring waste directly to the facility in a meticulous andconsiderate manner. Going forward, we fully expect you to continue to operate the facility withan even greater focus on safety, peace of mind, and reliability over the next 20 years.
