Abstract
The purpose of this research is improvement of Japanese forestry. So I decided to consult the following two. The first is German forestry. The second is the enterprise which succeeds in Japan. By this,improvement of the productivity and safety are enabled.
In present Japanese forestry,About 90 % runs the business on a small scale. Therefore large heavy industry machinery and high-performance equipment can't be introduced. So I think an enterprise is helped by a low-price application development.
