In view of the pattern of world distribution of forest and their utilization, it may be reasonable to anticipate increasing international pressure to interject forests of Japan for domestic use of timber. And the cutting-activity in the private forest must not be increased for the sustainable use without institutional support. However it is not easy to identify the factors that contribute to the cutting-activity for utiligable purpose so, it is also difficult to take measures to cope with the situation. This study was done in order to identify the factors that determine the cutting-activity. First, we grouped fifty-four cities, towns, and villages in Gifu Prefecture into several types by "factore analysis" and "cluster analysis" with eleven factors related to forestry such as forest timber volume, infra-structural facilities, labour and groups, the industry of /sawing logs, log price, and volume of timber cut, in each combination of two species; Sugi (Cryptomeria japonica), Hinoki (Chamaecyparis obtusa), and two methods of cutting tree. Next, volume of timber cut was analyzed by "multiple regression analysis" with eleven factors to see if there is a correlation. The results show that three factors, the industry of sawing logs, labour and groups, and log price determine the volume of timber cut. This relationship was clearly observed in the Tono district and its outskirts. I may be concluded that the quality of production center eventually determine the cutting-activity.
