Japanese ink painting, known as sumi-e, is a traditional art form that emphasizes simplicity and the beauty of nature. Artists use black ink, made from soot and water, to create expressive brush strokes on paper or silk. The technique focuses on capturing the essence of subjects, such as landscapes, flowers, and animals, rather than detailed realism. The practice of sumi-e dates back to the 14th century and is influenced by Zen Buddhism, which values mindfulness and the spiritual connection to nature. Artists often use a limited color palette, allowing the ink's varying shades to convey depth and emotion in their work.
