Enriching life through trees grown in forests

Aiming for a future in which cities and nature coexist in harmony

The Mitsui Fudosan Group is cultivating about 5,000 hectares of forests in Hokkaido and is striving to create sustainable forests that will last into the future. Here we will introduce the forests we are growing.

Our forests

View data about Group-owned forests and our reasons for cultivating these forests.

Location of Group-owned

We own forests in 31 cities, towns, and villages concentrated in northern Hokkaido.

Forest area


We own and manage roughly 5,000 hectares of forest in 31 cities, towns, and villages in Hokkaido (especially northern Hokkaido).

Area of 1,063 Tokyo Domes

※Tokyo Dome is roughly 4.7 hectares

Our reasons for cultivating forests

Our reasons for cultivating forests are deeply connected to the situation of Japan’s forests and global environmental destruction (such as illegal logging). Japan is a heavily forested country, with about 70 percent of its land area covered by forests.
About 40 percent of these forests are planted forests, which are artificially cultivated mainly for wood production. Proper management through manual labor is essential in order to keep planted forests healthy.
However, since the liberalization of wood imports, the price of domestically-produced wood has remained stagnant. This has caused people to shift away from the forestry industry, leaving many planted forests in an unmaintained state.

Creating “never-ending forests” for the future

Planting saplings, cultivating them appropriately, and using the trees harvested from these forests.
Through this cycle, we are working to create sustainable forests that will last into the future.

Helping to mitigate climate change

Forests help to mitigate climate change by absorbing CO2 and supplying the oxygen that we and other living organisms need to live.

Biodiversity conservation and creation

Just under 40 percent of our forests are natural forests dominated by Mizunara oak and other species. We strive to preserve these forests in their natural state with minimal management.

About 40% of Group-owned forests

Natural forests

Forests created by nature that support a wide variety of tree species.These forests are left in their natural state, without much human intervention.

About 60% of Group-owned forests

Planted forests

Forests made up of saplings planted by humans, predominantly coniferous trees. These forests require appropriate management by humans, such as underbrush clearing and pruning.
