Dependences of vibrational properties of wetwood of Todomatsu (Abies sachalinensis Mast.) on moisture content were compared to those of normal part whose moisture content was not so high. Specimens were cut from the wetwood and normal part, and matched in the R-direction. After oven-dried at 105 deg C, a free-free vibration test was conducted at room temperature and various relative humidity conditions. Changes in moisture content with relative humidity of the wetwood were similar to that of the normal part. There were no serious differences of changes in vibrational properties between the wetwood and normal part.
