Ink painting and oil painting, literally water and oil, are opposites and should be expressed naturally. East and West, if you analyze them, it's troublesome, but as my teacher, who was an ink painter, said, I think it's okay to say that what the Japan painted is Japan painting.
His teacher, Katake Murakami, called the painting a "prayer behind closed doors." The child with paper and crayons in his hands forgets himself and is immersed. At the root of all of them is the work of life, its joy, and the method of expression. Draw what you want to draw as you want to draw, that's all.
