Mr. Okamoto worked actively during the 1970's and 1980's, but did very little work during the 1990's. His technique is very painstaking as he applies the color to the copper plates which have been etched. He uses one plate for each of the different colors in the composition. He sometimes uses various sections of the plates to utilize the copper plates to the fullest extent.
His work is of the highest quality and he is known throughout the world for fine textured, colored etchings, which are completed in a totally Japanese manner (one plate for each color in the composition)
