Initiatives for environmental protection

The tree grows slowly over a long period of time. Nothing reaches the logging season in a single year.
We believe that it is also our role to convey these value and precious resource given by nature to the society.
We are also working to promote the use of planted trees,such as Merksi Pine, Radiata Pine, and Rubber wood, and to supply sustainable forest resources.
In addition, illegal logging and destruction of the forest environment are regarded as problems. Our basic concept is to handle products made from legal woods, and we are also certified as a legal timber company.
