Born in Edo, name Motonaga. At 18 years old, he became an apprentice to Sakai Hoitsu, and after the death of Hoitsu’s apprentice Suzuki Reitan, married Reitain’s sister Riyo. He became a retainer of the Sakai family. Hoitsu had great confidence in Kiitsu, and often entrusted him with painting in his stead. Faithfully inheriting his teacher’s style, he then pursued his own style after his teacher’s death. He specialized in paintings of flowers and birds, and established a new kind of Rimpa-style expression with his sharp senses in drawing from nature, backed by observation of the natural world. He also left behind pieces such as e-byoso (a kind of trick painting in which the mounting itself was painted on). He died at 63.
