Iemitsu enjoyed painting and sometimes gave his works to retainers, museum officials said. Less than 10 drawings by Iemitsu survive. They are all executed in a simple style, according to Nobuhisa Kaneko, curator of the museum. "I cannot tell if Iemitsu intentionally painted badly, but it was his style," Kaneko said.
"Horned Owl" depicts a bird with an innocent-looking facial expression. It has been stored at Yogenji temple in Tokyo's Bunkyo Ward. "Rabbit" was discovered in Kyoto several years ago. It depicts a hairy animal perched on a stump with big black eyes. The drawing is mounted on a hanging scroll with a crest of hollyhock that symbolizes the Tokugawa clan. It was kept in a heavy box and handed down through generations with great care.
