Koho Yamamoto is a master of Sumi-e, the traditional Japanese art of ink painting, known for its expressive brushwork and philosophical depth. Her artwork spans from minimalist abstractions to evocative landscapes, often rendered in black ink with subtle tonal variations that convey emotion, movement, and atmosphere. Her later works include bold, abstract compositions that maintain the meditative quality of Sumi-e while pushing its boundaries. These pieces often explore "nothingness" and presence, as she puts it: “My paintings come from nothingness.”
