The moisture reduction in fuelwood of Japanese cypress (Chamaecyparis obtusa) and evergreen oak spp. (Quercus glauca) was evaluated under some conditions differentiated in split sizes (one quarter or one eighth), drying area (paved or unpaved, roofed or unroofed), and season (winter or summer). Japanese cypress dried out more rapidly than oak. Splitting enables the acceleration of drying rate and size effect was more enhanced in oak with higher wood density. Any benefits of natural seasoning were realized within the first one or two month. Under natural seasoning with uriroofed condition, there was little benefit in longer drying period of fuelwood in terms of rainfall.
