Tomb Mounds for Requiem

・Shore Scape for the Requiem“Disaster Wave to the Hope Wave”“Requiem for the Spirits of the People, still
floating in the sea, after Tsunami’s drawn out”
“Take Energy from the Nuclear Polluted Sea”
to the Requiem by making the Mounds by theDisaster Waste.
Each mound can be made by the InternationalDonation, 20m high, 300m wide, waving mounds
・Souma- Futaba Area: 1,303 death +21 lost・Souma- Futaba Area had many ancient Tomb
Mounds in 3~6 century.
・Wind Power generation on the Sea wall
・Medium Wave Power plants on the 5m shore
・Big Wave Power Plant on the off shore line,
Ocean Wind Power Plants on the 30km

・FINAL TARGET： To create the most Sustainable City and most Respectable Society of the World,by creating the Low Carbon, Recyclic and Multi Biodiversity Society.
2-1 Principle① Purpose
・To give hope to the escaped People to be back home in the future.
・To present the value of the land to the villagers, being evacuated long period, in order togive them peace of mind and economy.
・ To break through from the Nuclear and Fossil Energy.
・To Break through from the normal living standard.
・Every waste materials, disaster rubbles, living waste, energy and thermal abolition, will
be recycled as treasures.
Air; Wind, Light; Photo voltaic energy, Heat; Solar heat
Timber; Forest Timber, Forest Waist, Construction Timber, Disaster Waist Timber
Water; Rain Water, Pond, River, Sea, and Wave
Waist; Home Waist, Industrial Waste, Agricultural, Cattle farming Waste, Sewage etc.
Ground Source Heat ; Hot Spring Water, Water, Circulation Water drawing heat
・To Create splendid society for the village people to be a leading character and live with
their own pride.
to hold their history more valuable, to love the nature, to bereave their community
friends, people, and to help, give, share with the family of the community.

■Basic Concept for Ideal Environmental City■

②Proposal
1．To Propose 3 term recovery plan for Short(3y), Medium(10y), Long(20y).

Ground Level Dose Rate（April 29, 2011）

2-1．Short term plan for Tsunami sea water covered area, to recover supply water anddrainage water channel and pump stations for 3 years.
2-2．Short term plan for the preparation of the methods and system of Dis-contamination of
the Radioactivity for 3 years.
2-3．Short term plan for the temporary Housing and to develop the preparation estates, andto recover East-West road network for 3 years.
3．Medium term plan for the recovery of the regional economy, by industrialization of thenatural and renewable energy and the recover activity.

Hopeful Wind

4．Long term plan for the land use of radiation contamination area, to convert to Biomass
Agriculture Field and/or Natural and Renewable Energy Plant, with Smart Energy Grid System.
5．Biomass Power Plant to use Biomass Agri-Products and/or Urban Waste, converted fromexisting Thermal Power Plant and Nuclear power generation system, or to construct dispersed
medium size power plant in the area of between30 ~50km.
６．Wind Power Plants on the hilly area and on the shore

Seamen missed their sea,
Farmers missed their land,
Merchants missed their market,
not by their own will.
Families separated in several houses,
Communities separated in some areas.
Still130,000 people lived apart from home.
Still Namie Town/ shore area clean up.
Still many people lived in emergency house.
Government only manage their wills.

Many constructional demand increased, thedevelopment babble occurred.
The construction cost has been higher, lack ofworkers, rejection new work, etc.

beforeRecover housing development started in public,
very few in private houses.
Because of their lost/ smelled property
by Tsunami and Nuclear Accident.

11,March 2011, Tsunami attacked and Plant
Stopped by emergency electricity stopped.
Melt down of the core happened and hydrogenburst destroyed No,1,2,3,4 plants.
In 2014, many tanks are set on the hills.
Nuclear contamination water is most difficult ,360,000tons stocked, 400tons/d increasing
30m Ice bar walls will be put around the plants(1500m) 30~40years needed to finish

Recovery Development Scheme

People’s Participation by work, things, money and wisdom

・Development Managing Council to be organized, distributing the individual benefit from the energy
development to public for every people, in order to encourage the Local Economy, and to avoid to makeany meaningless disparity.
・The Council evaluate the proposals from the SPCs of projects, adopt the SPC which will contribute tomake equity for people. To execute the projects, step by step with confirmation of the value on theprocess.

①Recover Living Standard 3
Proposal for the recover infra-structure, East-West road and Recovery Preparation Estate■■The 70,000 population of Minamisoma will be shrinking to 45,700 to32,500, whichis almost 65 to46%.

■■We have to plan for approx. 45,000 city, not for 70,000 city.
■It will need the Compact City reformation with economical and financial plan.
Three Districts, Haramachi, Kashima and Odaka, will be the centers for the activity.

■■The area is restricted in 2km diameter, in Haramachi and Kashima district, and■500m in Odaka District, where, 15,000 to 25,000 city will be planned.
■The City center has been osteoporosis in the urban diagnosis for its vacant situation.
■We propose to introduce the Walking, Bicycling and Demand Bas System in thecenter, and strengthen Educational, Cultural, Welfare and Medical functions, with its
Historical Features, rather than Commercial activities.
•■■The conversion from the right of the land■ownership to the right of the land use will be■planned, for making more fluid and vitalize theeconomy and peoples’ activities.
•■The medium size housings will be constructed
for the elderly and young family, and to growthe population in the center/•■Commercial facilities are gathered along theby-pass road, the neighbor hood commercialand communication spaces for the central area.

Central area of Haramachi District., many vacant houses and lands are observed.

•■Buildings are kept the Basic Environmental
Quality for the Zero- Emission buildings.

•■Community Living with dining and bath withmulti-generation is based to help each other.

zero emission quality is needed even for the temporary houses—■The Zero Emission Quality is needed even for the temporary houses■The temporary houses have many problems, such as narrow, they are wasted after2years life,
low quality of the environmental conscious, etc.
■I propose prefabricated Rack-Joint Method System, which is dismantled smoothly after therole of the temporary houses, and reconstruct for the second story houses with double
materials.
■It has a high performance quality of the basic environment with low energy consumption.

Fresh air is coming through under ground pipe and heat exchanged by the waste air under the floor. Highefficient (4~6cop) air compressor equipped in the under floor, heighten the intake air, which will make warm
the concrete mat slab, and then finaly take into the room. These air circulation using the passive method
make the heat loss smallest, and to store the heat in the skelton, then the energy consumption to be smallest.
