(Nagano) -(2002) @Sabo Engineering (Erosion Control Engineering) The goal of the Sabo Engineering is the mitigation and prediction of natural disaster from the aspect of sediment producton and transport systems. Recently the Sabo Engineering turn the attention to the riverine and aquatic environments linking with channel works and dams. @Revegetation Engineering Restoring and improving the natural environment of the earth, which keep devastating recently, the functions of vegetation can provide the first aid develop the sustainable landscape. Our research goal called as Revegetation Engineering are both establishing the plant society and understanding the plant influences on the devastated earth surface. Today our research activities expand to desert land, arid land, and steep land in the world. Our research experiences can be utilized for technological development of natural rehabilitation based on the plant succession.

(Okayama) -(1999) We are pursuing the environmental contribution through Manufacture and sale of vegetation products, Sale of construction materials and products for Environmental safeguards, Engineering and construction work for erosion control, and Design and installation of sports facilities.
