Abstract

A market-oriented industrial structure is required to stimulate the forestry and wood industry in Japan. Such a structure is necessary to develop the system of stable timber supply and appropriate forest management. We surveyed sugi (Cryptomeria japonica D. Don) plantations in Akita Prefecture to clarify the available timber volume based on current use and application. We also estimated the currently available and usable timber resources. The highest proportion (40%) of total timber volume was that of currently available timber. The total volume of forest stands was classified as available for harvest if the stands occurred on slopes with an incline of less than 20° and were less than 50 m from a road; these stands occupied about half of the total volume in all age classes. Judging from our results, we are convinced that present resources should be sufficient to meet demand for a decade from wood industries in Akita Prefecture. The sustainability of a long-term stable supply, however, is uncertain and additional studies would be needed. We anticipated that constructing the datasets of wood resources is conducive to implementation of appropriate forest management to meet demand for the forestry side. Such datasets are also conducive to the demand growth and new demand reclamation that is designed with the future of quality and quantity of resources for wood utilization in mind.
