Master painter and founder of an eponymous school in New York City where she educated generations of students in sumi-e (“black ink painting”) from 1974 to 2010, Masako “Koho” Yamamoto (b. 1922) continues to work and teach privately as she approaches her ninety-ninth year. Because of her deep association with sumi-e and veneration as a teacher, her art has been almost totally unrecognized outside of that context. These dark abstract paintings suggest sublime interior landscapes, which she describes as coming “from nothingness”—from an empty mind.
