"Recently concern about the forest amongst general citizens is becoming very high in Japan. Despite this interest, over 80% of artificially planted forests which make up 41% of forest area lie unmaintained. Proper management techniques such as thinning out tree densities have not been maintaind leading to stunted tree diameters to heights, Iack of sufficient sunlight in forest stands and unhealthy condisions. As a result of this tree is a low expectation that tree forests can be of use for future wood production, and the possibilityis of the occurrence of disaster exists. The comditions discribed are also conspicuous in naturally regenerated broadleaf tree forests. The causes of these problems are caused by a lack of sufficient maintenance and use. These days, forests are recognized as not only the place for wood production to be carried out, but are soon as place carrying out various functions. These functions are indispensable for safe and comfortable life for general citizens. This author proposes the introduction of new technology for forest maintenance. A heavy thinning of tree densitis to bitween 30%-60% is recommended reading to a number of factors. The expected outcomes include an increase in tree health and growth in diameter to height. Forest tree root systems and undergrowth will develop leading to improved soil and water conservation functions. Furthermore, the landscape of forest stands and habitation environment of various wild animals and plants will be improved. Improvements in the wood production functions of forest stands can be expected leading to long rotation and large diameter management techniques."
