Basics of Japanese Forest

Let's get it started!
Oh, before anything, as I have no experience of writing, please be patient even if the composition is difficult.

At first, I will show you the very basic data.
Japanese land area is about 380,000 m2.
66% of it is covered from the forest, which is the second highest percentage in the world.
Japanese precipitation, humidity, temperature and soil are easy for trees to grow.
So naturally the land becomes the forest if no one takes care of the land.
Japan is long vertically and holizontally. So we have many vegetation place by place.
(Like the plant in Hokkaido is different from those in the main land)
Natural forest has Oak, Beech, Maple or Birch(Normally broadleaf/evergreen tree grows in the south and coniferous/deciduous grows in the north.)

40% of whole forest is artificial.
The main species are Japanese Cedar, Cypress, Pine, and so on.

30% of whole forest is owned by Japnaese government.
Big companies like Toyota, Mitsui Bussan, Oji Paper, Nihon Paper, Asahi Beer, Sumitomo Forestry have more than 40,000 ha of the forest (maybe).
But mainly forest is divided by so many small owners.

The annual comsumption of timber per Japanese person is between 0.8 and 1.0 m3.
The main ways to use timber in Japan are the construction materials and the paper.

Many things are left to write down but this is enough for today!
