Haru" Opus #1305, Saga Prefecture, Japan. Rape blossoms on the riverbed of Kasegawa River, Saga Plain, Saga Prefecture. (Oil crayon (oil pastel) on watercolor paper The original drawing method (KOOSAIHO) uses nine colors of oil crayon (oil pastel), adding white to the eight colors of the rainbow (rainbow + red/purple), and focusing on the colors of the rainbow that permeate the natural world, rubbing each color on the belly of the finger, layering them in a unique order, then smashing, rubbing, and scraping with oil. The artist rubs one color on the belly of the finger, overlaps the colors in a unique order, and then rubs, rubs, and scrapes with oil to create overlaps of color and approach the deep colors of the natural world. The red bridge that crosses the northernmost point of Nagasaki Prefecture in Kyushu, Japan, is the Hirado Bridge. The Ikitsuki Island is across the sky-blue bridge that comes into view when crossing the Hirado Island. I fell in love with the nature of this Ikitsuki Island and am currently in the process of opening a gallery in the northernmost part of the island (2024.9). All of his works are one-of-a-kind. The impression changes depending on the place (light source) where you look at them due to the rainbow color layering effect.
