Changes in the moisture content of Japanese cedar (Cryptomeria japonica D. Don) green wood for columns with the dimensions of 110 x 110 x 1000 mm during drying in environments of over 100degC and 1 atm were measured. Temperature and mass were measured in an airtight chamber. The set temperature and gauge pressure ranges were 110 to 140degC and 0.01 to 0.24 MPa, respectively. The experimental measuring system was suitable for understanding whether or not the mass of the specimens was stable. The change in the temperature of a specimen was roughly divided into 4 ranges. At lower temperatures and pressures, the equilibrium moisture content was similar to previous estimates and measurements, while at higher temperatures and pressures it differed from the previous values.
