Tawaraya Sotatsu, who emerged from Kyoto's merchant class, was one pioneer of the Rimpa School in the early Edo Period, and Ogata Korin consolidated it in the mid-Edo Period. The school is not hereditary but is propagated by artists, who admire Sotatsu and Korin, and follow their styles. Rimpa is characterized by a notable use of space; abstract, vibrant designs; and creative playfulness. The works of Kyoto-based Nihonga artists continue the Rimpa style 400 years after its inception.
