The moisuture condition of Shiitake (Lenitinula edodes (Berk.) Peglar) bed-logs is important for mycelium growth. Incubation of bed-logs is commonly carried out at cutover in Oita prefecture, but me effective water sprinkling for incubated bed-logs was not done out in the fields.The effect of moisture content of bed-logs and spawn were studied for incubating at artificial spawn run area. Quercus acutissima Carruth.and plug spawn was used for Shiitake bed-logs cultivation in this study. The optimum moisture content for growth of Shiitake mycelia from plug spawn ranged from 33.8% to 53.0%. Mycelia could not grow when moisuture content was less than 20% in plug spawn. On the other hand, the moisture content of inoculated plug spawn suddenly decreased in fine days. It fell down below 20% after 4 days. Incubated bed-logs was physically changed by growth of Shiitake mycelium. The effective water sprinkling for bed-logs between spring and summer was considered to be twice a week (2hr per each time). It was very important to con-torol moisuture content directly after spawn inoculation.
