To optimize a crushing and transportation system, branches and tops, short stems, and mixture of branches and short stems of sugi (Cryptomeria japonica) were crushed to chips at the site using a mobile crusher or at a plant using a stationary crusher with screens of round holes of 30, 50, and 70 mm. The productivity and energy consumption during crushing were measured. The productivity of crushing short stems using the mobile crusher was lower than that using the stationary crusher, while the productivity of crushing branches and top-end using the mobile crusher was higher than that using the stationary crusher. The energy consumption of crushing for the stationary crusher was lower than that for the mobile crusher. In terms of screen hole size, the productivity was higher and the energy consumption was lower with the larger hole.
