PROBLEM TO BE SOLVED: To provide a method for preventing the occurrence of wood breaking which can prevent the breaking during a wood drying process without forming a break or a groove in the wood and improve the commercial value of a wood product. SOLUTION: First, the surface layer 1a of lumbered wood 1 is heated and softened. Next, the surface layer 1a is pressed to be compressed/deformed, and the compressed/deformed surface layer 1a is cooled to solidify the compressed part. In this way, during the drying process, since the surface layer 1a of the wood 1 is contracted in advance, the texture of the surface layer 1a is swelled when heated, and tensile stress is absorbed by the elongation of the surface layer 1a by the recovery from the deformation during drying so that the breaking of the wood 1 in the drying process is prevented.
