●About this driftwood
This is a driftwood at Kiso River. This kind is Japanese cypress, and it is representing Kiso River.
As for it, the climate and the geology of a local area are concerned deeply.
This quality of the material has little distortion and white, fragrant, mothproof.
This tree has more 260 annual rings, and probably it was passed at the dry river bed for about 20 years, after it was flowed.
And Japanese cypress have many historical things. It is the best material for Japanese archtecture.
After period warring staes(early17th Century), By the rushes of city foundation, the mountain at Kiso went to stark.
Then Shogunate gaverment covered with severe protectionism "One tree, one head".
It is this reason that the forest of beautiful Japnanese cypress remain in the Kiso valley even now.
However, it forced the local people severe life. It was only the purpose to protect treasure cypress.
At Kiso valley, felled trees were poured to the middle stream of Kiso river, log by log..
But forestry also changed a lot for Electric Power Development. The dam was built and the forest railway was built.,
It replaced the forest load before long.
Forestry was prosperous by the bequest of the past cypress before 40 years. But now Kiso valley is going to desorate with the cheap wood from foreign country and decrease in population. Japanese cypress forest is going to ruin, too.
