Overview of■Forest creation as a collaborative effort
Composting

The compost necessary for theplanting base of Umi-no-Mori ismade from pruned branches andleaves from park and roadsidetrees in Tokyo's 23 wards. Thismethod was taken to eﬀectively
use resources and reduce costs.

The Tokyo Metropolitan Government is turning land in Tokyo Bay, which has been reclaimed with waste
and construction-generated soil, into a beautiful lush forest by planting tree saplings. Based on thefollowing two concepts.

RTokyo Umi-no-Mori Club membersare companies and organizations
that support the Umi-no-Moriproject. Various attracti ve events
are hosted by the members tointroduce Umi-no-Mori to as many
people as possible.

Soil created with compost
1.5 meters deepIn the center of Umi-no-Mori is a field for various
events and relaxation, and woods for enjoying
outdoor recreation. As protection from the strong
and salty ocean breeze, priority is placed on
mounding earth around these spaces anddeveloping the Forest of Breezes with evergreens
resilient to powerful offshore wind and salt
damage. Serving as a wind break and sea wall, thisforest protects plants in the field and theenvironment, and makes it easier to hold eventsand facilitates citizen participation.

Wildlife

Afforestation by coastal tree species, such as Chinquapin and Machilus, is underway on the slope facing
the sea, which is exposed to strong sea breezes. Only tree saplings indigenous to the Kanto region are
selected to ensure genetic integrity. Once grown, salt-tolerant trees provide shelter for other plants togrow, and over time, become habitats for a variety of life, including insects and birds. The site has alreadyattracted many living organisms, and is gradually transforming into an ecologically rich forest.

Umi-no-Mori offers habitats for a variety of life.

Activities from growing and planting
tree saplings to nurturing forests are
conducted with Tokyo citizens andprivate businesses. Tree saplings are
pur c ha s e d w i t h dona t ions f r o mresidents and companies. Elementary
school children and volunteers raise
the tree saplings from acorns. Treeplanting and management are alsodone with the support of residents,companies, and other organizations.

Main types of trees
The goal is a mixed forest, mainly salt-tolerant evergreens, such as Machilus, and deciduous trees,
including Oshima Cherry and Mulberry. The wildlife-friendly "Woodland Sanctuary" has many trees thatfeed birds and insects, such as Bayberry. With the help of nature, this will become a biologically diverseforest.

Umi-no-Mori was created from 1973 to 1987 from 12.3
million tons of alternately layered waste, excess
soil, and other materials. In order to turn the30-meter high mountain of waste into a forest, a
1.5-meter deep planting base was built from top
soil, which is a mixture of compost, soil amendment,
quality soil, and construction-generated soil.
Compost from pruned branches from roadsidetrees was used until completion of construction.
Both resource recycling and cost reduction wereachieved in this way.
