I am producing lithographs of all the　print works. Technically speaking, I use traditional stone plates, zinc plates, and aluminum plates polished with emery and dressed. I draw by hand only, using crayons and India ink. Although they are often mistaken for photolithographs, they are all hand-painted and, of course, I do not use a computer. I usually use about 8 to 10 plates. The works and the techniques are inseparable, and as someone who started from the old techniques, I treasure those old techniques for creating my work.
