  • Reforestation Activities


Forests are essential for watershed conservation, preventing mountain region disasters, health culture, and preventing global warming. Forests give richness to our lives and are vital for our souls. An important role of the organization is to exercise stewardship over the region's forests to ensure that future generations can enjoy their benefits.

For generations, the forests have provided people with resources such as fruits, mushrooms, and timber, bringing enrichment and a sense of peace. The forests also provide a wide variety of other important services, including the protection of our water source, minimizing disasters in mountain regions, nurturing overall good health, and mitigating global climate change. The Onshirin Regional Public Organization has been working as stewards of the region's forests to ensure that future generations can continue receiving the same benefits we enjoy.


The forests spread across the base of Mt. Fuji has been re-forested and maintained through countless generations. These forests are the Onshirin Regional Public Organization’s invaluable legacy and treasure. Each and every tree in these forests has been carefully planted and maintained by the preceding generations. The mission of our afforestation efforts, therefore, is to protect and value these trees and the land at the base of Mt. Fuji.


Afforestation is essentially an act of raising a forest. It starts from preparing the grounds in deforested areas so that new trees can be planted. After the seedlings are planted, it is important to remove excess brush and control undergrowth in order to maintain an environment with good air flow and sunlight for the young trees. Regular thinning of the threes is important in order to improve growth. Effective management of the forests is therefore essential in order to receive the wide range of benefits the forests provide.


Appropriate conservation and management of the land and timber production efforts continues on the north slope of Mt. Fuji, in the forests that have been passed down through generations. We are also increasing our efforts to provide healthcare and recreational opportunities for the public community. Through developing more creative and original afforestation practices to include forest environmental education and experiential educational opportunities, we are working towards expanding the possibilities of the forest as a truly communal resource.




Site preparation
Tree planting
After the felled trees are cut into logs, the branches, brush, and roots are gathered together so that they can be easily removed. The seedlings are planted from April through May. Removing the surrounding wood chips and weeds, each and every seedling is carefully planted.
Undergrowth Removal
Improvement Cutting

To ensure healthy seedling growth, the surrounding brush is removed. This helps to promote efficient water and nutrient uptake and protection from pests and diseases. This work is done during August, and is continued for the first 5 years after the tree seedlings are planted.

Unwanted species such as invading trees and ivies are removed to make sure the young trees have access to sufficient sunlight, air flow, water and nutrients. This work is typically done four times in the 10 to 30 years after the trees are planted.
Tree thinning ensures that the trees are provided with proper space and sunlight for them to grow healthy. This is done in order to produce high-value timber, and it is done several times once the trees are 15 to 30-years old.
