Forests create the timber resources that are vital to our daily lives.
However, we need to care for them for many years
to produce stable supplies of timber.
Planting, clearing undergrowth, improvement cutting, thinning, and final cutting,
all done using the knowledge and techniques of Japanese forestry
that we are heir to, are some of the ways
we work to ensure that rich forest resources remain intact.

Forests we manage and operate

The approx. 188,000 ha of forests we manage and operate covers about 86% of the total area of Tokyo Metropolis (220,000 ha), making us the largest private-sector owner of forests in the country.

Forestry Management

To achieve sustainable forest management, the Oji Group has set out a Management Plan for Company Forests, and carries out forest creation and timber harvesting according to this plan, working to protect the environment and maintain biodiversity. In addition, we use the techniques we have learned from our company forests for creating forests and harvesting timber for both state and private forests.

Forest Regeneration

Much of Japan’s plantation forests are reaching their harvest period, but timber production is stagnating due to the pressure of cheap wood from overseas. We aim to regenerate the forests of Japan, expand their scale through links with forest owners, and bring in high-performance forestry machinery to help us improve productivity.
