Seminar objectives

The forested area in Japan has been miraculously and consistently kept at the constant level of 67% of the land area (about 25 million hectares) for a long time despite pressure from an increasing population and industrialization. Simultaneously, wood products have always supported Japanese culture and civilization. A lot of wooden temples and structures built several hundreds years ago still exist in amongst modern buildings. In addition to the traditional forestry plantation areas, coniferous trees have been planted every year since the 1950's and incredibly, those from this plantation have since occupied about a quarter of the land (over 10 million hectares). Conifers requiring thinning occupy the majority of the existing plantations.

However, the Japanese forestry industry has been in economic difficulty trying to survive in the global market. In spite of the potential timber production, the domestic production supplies only 20% of the demand mainly due to the high production cost caused by a gradual rise in labor wages and steep mountainous terrain. This is why Japan is one of the largest importers of timber and timber products and is sometimes criticized as an excessive consumer of natural forests outside Japan in both the tropical and the boreal zones.

In the new century, the severe demands for forest resources including not only wood materials but also for the environment and various public benefits will increase more and more in the world. Tending and harvesting plantations will soon be given the priority over protection of natural forests. Forestry operations especially in young stands will have to meet economic and environmental conditions to implement sustainable forest management.

The objectives of this seminar are to exchange our accumulated knowledge, experience and technology, and to discuss philosophically and technologically how we can approach the issues of tending and harvesting operations of plantation forestry against the increasing cost while giving consideration to the environment and human factors. Various kinds of small forestry machines and narrow strip roads playing an important role in Japanese forestry will also be shown on the field trip of this seminar.
