PROBLEM TO BE SOLVED: To provide the grain emphasis method of woody material of inexpensive manufacturing cost, for impregnating a pigment even into a thick woody material. SOLUTION: The grain emphasis method includes: a decompression process 100 for putting the woody material with bordered pits not completely closed, such as radiata pine, into a pressure vessel and for decompressing it; an injection process 200 for filling an aqueous solution with the pigment consisting of particles capable of passing through the bordered pits of the woody material added thereto into the decompressed pressure vessel, pressurizing the pressure vessel, and injecting the pigment into the woody material; a drying process 300 for drying the woody material with the pigment injected thereinto; and a working process 400 for cutting off the front surface or the front and rear surfaces of the woody material after drying.
