Mt. Fuji Manabi no Mori Project

We are continuing the Mt. Fuji Manabi no Mori Project which began in 1998 to commemorate the 50th anniversary of the Company's establishment, setting out to restore the vitality of the rich national forest cloaking the foothills of Mt. Fuji that was extensively damaged by a typhoon. Today, this project visualizes the progress of tree growth in survey areas of planted regions and oversee natural forest recovery of Mt. Fuji Manabi no Mori.

In fiscal 2019, the Mt. Fuji Manabi no Mori was used for volunteer activities, environmental education programs as well as opened to NPOs and other organizations. A total of 1,554 people visited Mt. Fuji Manabi no Mori from inside and outside of the Company with a total of 29,818 people visiting the project between fiscal 1998 and 2019.

Volunteer Activities in Forestry Development

Since the start of the project in 1998, up until now, a cumulative total of 28,000 volunteers have helped to plant approximately 30,000 region-specific saplings and conduct other forestry efforts.

To date, reforestation efforts of national forest damaged by typhoons were completed as the first phase by removing the hexatubes. In fiscal 2019, a tree survey began as a monitoring survey necessary to comprehensive forest management activities. As the first year of this tree survey, 189 volunteers took part in creating a database from records of 495 trees planted on approximately 1,800 m2 over four days under the guidance and cooperation of arborists and other tree experts.

The Manabi no Mori project will shift to a more suitable forest for learning by visualizing the growth of the trees that have been cultivated by the volunteers.

Environmental Education Program

Sumitomo Forestry has been implementing an Environmental Education Program for local elementary and junior high school students since fiscal 2006 in collaboration with the NPO Whole Earth Institute. Activities include nature observation and games incorporating the five senses. The aim of these opportunities to rediscover the natural world is for the students to learn about the importance of nature and encourage them to consider new ways in which people can coexist with nature in the future. In fiscal 2019, a total of 1,101 students and children from 13 schools were invited to the program. A cumulative total of more than 10,000 students and children have been invited as of fiscal 2019.

Vegetation Monitoring and Wildlife Habitat Survey

We have been conducting vegetation surveys since fiscal 2000 to monitor the recovery of the natural forest under the guidance of Vegetation Management Science Laboratory, Tokyo University of Agriculture and Technology. From the same year, we have been conducting wildlife habitat surveys with the cooperation of the Minami Fuji Branch of the Wild Bird Society of Japan.

The vegetation monitoring has been able to confirm the gradual growth of beech, Japanese zelkova, and other trees that were planted as well as dogwood and amur cork trees that grew naturally after the damage caused by the typhoon. Over the last 20 years, the survey revealed that the planted trees had not only gotten larger but entire species in the forest also recovered.

The environment where the ground was bare after the removal of fallen trees gradually transformed from grasslands to forests. With this, on the wildlife habitat survey, the population of pheasants and shrikes is declining, and in their place, the population of such birds of the forest as narcissus flycatchers and varied tit is increasing with opportunities to view them becoming more frequent, indicating that the forest is steadily recovering.

In fiscal 2019, we started a three-year entomological survey with the cooperation of Tokoha University professors. This monitoring survey will identify and list over 80% of the insect species living in Manabi no Mori with a large behavioral range.

Cultivating a forest is a never-ending job and Mt. Fuji Manabi no Mori, too, is a 100-year project. To ensure that the project is still running 100 years from now, forest management and environmental activities will be continued as a way to communicate the importance of nature to as many people as possible.

Advocating the Kanagawa Zero Plastic Waste Declaration

In February 2019, the Sumitomo Forestry sales offices in Kanagawa (Yokohama Branch, Yokohama North Branch, Kanagawa West Branch, Shonan Branch, and Tokyo South Branch of Housing and Construction Division) pledged their support for the Kanagawa No Plastic Waste Declaration. In the future, we will continue the beach cleaning activities that began in fiscal 2018 as well as providing environmental education for local communities about plastic waste.

Development of Technology to Pass Down Heritage and Precious Trees to the Next Generation

Sumitomo Forestry uses the most cutting-edge biotechnology in addition to conventional grafting and cutting based on the request of owners to pass down heritage and precious trees to the next generation. We are also putting our strength into breeding seedlings that provide the properties in the flowers and leaves of heritage and precious trees as a way to pass down both heritage and precious trees to the next generation. In addition, we are building a DNA database for trees to further advance a sophisticated program to identify individual varieties.

Successor Trees to the Miracle Pine Return Home:
-Rikuzentakata City, Takatamatsubara Tsunami Memorial Park Tree-planting to Commemorate the Opening of the Park-

The successor trees of the Miracle Pine cloned through grafting returned to their homeland in Rikuzentakata City for the first time on September 22, 2019. The “Miracle Pine” was the sole surviving pine tree from the tsunami caused by the Great East Japan Earthquake. Sumitomo Forestry attempted to cultivate successor trees to the Miracle Pine and, in 2011, was successful in using grafts and seedlings to propagate new trees. Three of these successor trees were planted for the opening ceremony of the Takatamatsubara Tsunami Memorial Park. It is hoped that these successor trees propagated from the Miracle Pine will become a symbol of protection against disaster and remind those to come of the Great East Japan Earthquake. These successor trees, together with Rikuzentakata City that recovered strongly from the disaster, will live on to a new tomorrow.

Sumitomo Forestry's Endeavour to Cultivate Successor Trees of the Miracle Pine

April 2011 Japan Landscape Contractors Association Iwate Division Manager Yoneuchi launches the Miracle Pine Rescue Project. Cuttings, graftings, tissue cultures and seedlings are all examined as possible methods of propagation.
December 2011 Three grafted saplings and 18 seedlings germinate
September 2012 Approximately 1,000 pine cones are harvested when the Miracle Pine is felled. Breaking down all of these pine cones, 75 seeds are collected
March 2013 Seeds collected in September of the previous year are planted.
June 2013 The 18 seedlings that germinated in 2011 all wither and die nine seedlings are successfully cultivated from the 75 seeds collected in 2012.
Present Three grafted trees and nine seedlings are growing well.

Start of the Oku Matsushima Natural Recovery Volunteer Planting Activity

Sumitomo Forestry entered into a partnership agreement on restoration property development coordination and cooperation with Higashi Matsushima City, Miyagi Prefecture in July 2012 after the Great East Japan Earthquake to make every effort toward restoration. Higashi Matsushima City aims to revitalize tourism by bringing back the wetlands in the Susaki district near the Nobiru coast devastated by the tsunami. As part of this effort, Sumitomo Forestry began trial tree planting activities in fiscal 2017. A soil investigation discovered a high concentration of acidity, which needed considerations about the tree species and techniques for planting. We then formulated a tree-planting plan taking into account third-party insight from the Tohoku Research Center of the Forestry and Forest Products Research Institute.

We could check and make sure the seedlings had been growing with support by local community, so that the Higashi Matsushima Nature Recover Volunteer Planting Activity started near Oku Matsushima “Kizuna” Solar Park along the Nobiru coast of Higashi Matsushima City In fiscal 2019.

On October 23, a total of 136 people from the local community, students from Miyanomori Elementary School in Higashi Matsushima and Sumitomo Group employees took part in planting 630 botanical plants, such as Japanese black pine and evergreen shrubs indigenous to Japan. This is a medium- to long-term plan executed together with the local community.
